[0.16.19] - 2026-08-24

If you are upgrading from v0.16.x, replace the binary (or run docker pull). If you are upgrading from v0.15.x and below, please read the upgrading documentation for more information on how to upgrade from previous versions.

Added

• WebUI: oauthClientId setting in Application, which allows the WebUI to use a different OAuth client than the default.
• Sieve: env.spam.score and env.spam.is_spam variables, which expose the spam filter result to system scripts running at the DATA stage.
• CalDAV: vCardVersion setting in AddressBook, which allows the default vCard version to be specified when the client does not request a specific version.

Changed

• MySQL & MariaDB: Key columns are now VARBINARY(255) with a full-length primary key instead of TINYBLOB. Note: Existing deployments should run, once per table, for each of the tables a, d, e, f, g, h, j, k, l, m, n, o, p, q, r, s, t, u, w, x and y the command ALTER TABLE a MODIFY k VARBINARY(255) NOT NULL;.

Fixed

• ACME:
  • Order and authorization failures are never logged, so an order rejected by the CA.
  • An order rejected by the CA marks the renewal task as permanently failed.
• CalDAV:
  • Attendee addresses whose mailto: URI percent-encodes a full name-addr are silently dropped from the scheduling snapshot.
  • Attendees whose calendar user address cannot be parsed should be flagged with SCHEDULE-STATUS=3.7.
  • The RSVP link in an iMIP invitation stamps PARTSTAT on the organizer's copy of the event only, leaving a local attendee's own copy at NEEDS-ACTION and sending the organizer no reply.
  • MKCALENDAR, MKCOL and PROPPATCH store the display name, description, time zone and the other per-user properties under the authenticated account rather than the account that owns the collection.
• Directory:
  • An empty column, attribute or claim returned by an external directory is synchronized as an empty string rather than a missing value.
  • /api/discover splits the account name on @ without accounting for the % master user separator or the recovery administrator.
• FoundationDB: Older chunked entries are not deleted.
• IMAP: SETACL and DELETEACL fail to resolve an identifier spelled with uppercase characters.
• iMIP: Invitations, replies and cancellations reference a TZID parameter with no matching VTIMEZONE component whenever the event was stored without one.
• JMAP:
  • AddressBook/get: A new account's default address book is never recorded.
  • Email/get and Email/parse with fetchAllBodyValues return body values only for the parts listed in textBody or htmlBody, omitting every other text/* part in bodyStructure.
  • Email/set writes display names as an RFC 2047 encoded-word wrapped in a quoted-string, which RFC 2047 forbids.
  • Mailbox/set, AddressBook/set and Calendar/set store isSubscribed and the other per-user properties under the authenticated account rather than the account named in the request.
  • Principal/query returns no results when the name or email filter is spelled with uppercase characters.
  • FileNode/set: File nodes created over JMAP are returned with a <D:href> holding the raw name over WebDAV.
• Meilisearch:
  • Queries return at most 1000 results, as the maxTotalHits pagination setting is left at the Meilisearch default.
  • Searches combining several terms return documents that match only some of them.
  • A task confirmation timeout is reported as a success when failOnTimeout is disabled.
• Import: --import always aborts with the target database already containing data in the key range being imported.
• MTA:
  • A domain catchAllAddress pointing to a mailing list or a sub-addressed mailbox is accepted at RCPT TO and then rejected at local delivery with 550 5.5.0 Mailbox not found.
  • is_local_address() and is_local_domain() expression functions do not match an address or domain spelled with uppercase characters.
  • Relay routes are rejected with host resolves loopback address, which prevents relaying through a local proxy or tunnel.
• MySQL, MariaDB & PostgreSQL: Range scans, range deletions and store purges run as a single unbounded statement, so on servers that enforce a statement timeout they abort on large accounts and tasks such as account deletion can never complete.
• Network: local_port and local_ip report the address Stalwart is bound to rather than the address the client connected to when the connection arrives through a trusted proxy.
• Task manager:
  • totalDeadline is not enforced on tasks that fail with a specific retry time.
  • Indexing tasks are dropped after maxAttempts failures, so a search store that is unavailable or overloaded leaves messages permanently missing from the index.
  • Indexing tasks are dropped when the document metadata read returns no data, which can happen on SQL read replicas that have not yet caught up with the primary.
  • The DNS management task republishes the DKIM records of retired keys that the DKIM rotation task had already removed from the zone.
• Sieve: spamtest returns only 1 or 10 (and spamtest :percent only 0 or 100), so scripts cannot act on intermediate spam scores.
• Spam filter: MIME_BAD is tagged whenever the declared Content-Type of an attachment is not byte identical to the type detected from its magic bytes.

Fixes and improvements

General

• prevent spamming of 'stream is closed' error during shutdown (#6062)
• impose a minimum value to clock rate of always-available tracks (#6086) Clock rates below 10 caused the emission of empty samples. Fix the issue by imposing a minimum value of 8khz, that rises to 22khz in case of AAC.
• fix race condition during sub-stream creation (#6075) (#6095) When a stream with always-available turned on switches from offline to online, or from a publisher to another, the reader mutex was not acquired during writing of codec parameters. This is now fixed.
• restore ability to run the server in a read-only file system (#6098) This was temporarily lost after the introduction of the native MoQ QUIC listener.
• fix deadlock when changing configuration through file and API (#6077) (#6101) When changing configuration in parallel by editing the configuration file and calling the API, the server could get into a deadlock that prevented any further action. This is fixed.
• change default value of authHTTPExclude (#6103) by default, do not exclude any action from HTTP authentication. Old value triggered several security warnings.
• add destFingerprint parameter (#6106) this allows to validate self-signed certificates of forward destinations.
• pmp4: fix panic in case of bad input (bluenviron/mediacommon#354) the stsc box was not checked properly. This is now fixed.
• pmp4: fix panic in case of bad input (bluenviron/mediacommon#355) The parser was not checking that the MP4 was properly sending addresses of samples, resulting in samples with invalid addresses. This is now fixed.
• pmp4, fmp4: do not emit empty payloads (bluenviron/mediacommon#353)

API

• redact password in responses (#6110) passwords are not exposed anymore through the API. They can only be set, not read.

Media-Over-QUIC

• support pulling streams from other servers (#6111)
• do not accept empty payloads (#6085)
• limit maximum amount of published tracks (#6087) this prevents clients from consuming an excessive amount of memory.
• make /moq URL suffix optional (#6107) In order to establish a MoQ session with WebTransport, a /moq suffix was required until now. This is now optional in order to allow connecting to the server with the standard MoQ URL format.
• impose maximum size on pending reordered bytes (#6112) Decrease the maximum memory that clients can take by imposing a maximum size of 100MB on the pending reordered bytes.

RTSP

• accept relative digest URI (bluenviron/gortsplib#1118) RFC 2617 section 3.2.2 allows the digest URI to be either an absolute URI or a relative path. Some clients use the latter, which was rejected with "wrong URL" since urlMatches only accepted an exact match against the absolute request URL.
• send initial RTCP sender report without waiting for a period (bluenviron/gortsplib#1052) (bluenviron/gortsplib#1111) (bluenviron/gortsplib#1120) Reports were emitted only on the ticker, so the first one arrived Period after Initialize (10s by default) and later still when no RTP packet had been sent by that first tick, since report() returns nil until then and the next opportunity is another Period away.
• ensure that decoders can produce only output that does not crash encoders (bluenviron/gortsplib#1123)
• discard empty Opus and G722 RTP packets (bluenviron/gortsplib#1131)
• improve error message when setting read buffer fails (bluenviron/gortsplib#1133)
• server: fix race condition when recording (bluenviron/gortsplib#1134) state was not protected.

RTMP

• inform about authentication failures (#5657) (#6072) Reply with NetStream.Play.Failed or NetStream.Publish.Unauthorized when a client is not authorized to play or publish. This makes clients like OBS to stop recreating the connection in case of authentication failures.

• reader: do not emit empty frames (bluenviron/gortmplib#106)

• parse video PTS delta as signed (bluenviron/gortmplib#88)
  HLS

• prefer hls.js on iOS too (#6090) In the embedded HLS reader, use hls.js on iOS, that was previously disabled due to compatibility issues that should have been solved.

• unlock the session-in-query+iOS combination (#6088) this was previously blocked because the session in query was meant to be dynamic, therefore incompatible with static playlists required by iOS. It is not anymore, so we can support that.

• stop using cookies with plain HTTP (#6089) in case of plain HTTP, fall back to query parameters, which are safer than HTTP cookies because they are not shared between different pages/domains, although they are visible in the URL.

WebRTC

• support forwarding streams (#6099)
• fix warning when IPv6 is disabled (#5733) (#6048)
• improve performance by ignoring mDNS candidates (#4963) (#6064) mDNS candidates sometimes require a large CPU portion, they are not involved in any connectivity method mentioned in the documentation, they work in local networks only.

SRT

• apply UDP read buffer size from configuration (#6069) Use upstream datarhei/gosrt's ListenerControl config field (datarhei/gosrt#144) to set SO_RCVBUF on the SRT listener's UDP socket.

RPI Camera

• fix crash when secondary stream is enabled (#6060) (#6061)
• prevent invalid MJPEG sizes (#6080) width and height of MJPEG frames must be multiple of 8 and less than 2048, otherwise they cannot be routed with RTP/RTSP.

[0.16.18] - 2026-08-17

If you are upgrading from v0.16.x, replace the binary (or run docker pull). If you are upgrading from v0.15.x and below, please read the upgrading documentation for more information on how to upgrade from previous versions.

Added

• Reporting: inboundReportMaxSize setting, which bounds the size of a decompressed inbound DMARC or TLS report (default 25MB).
• RocksDB: cacheSize setting, which bounds the total memory shared by the block caches of every column family (default 128MB).

Changed

• ASN & GeoIP: Default data source URLs now point at the ip-location-db GitHub releases, as the previously used npm packages are no longer updated. Existing installations keep their configured URLs and should update them following the ASN and GeoIP documentation.
• JMAP: Identity/get keeps identities in sync with the account's e-mail addresses.
• MTA: Queue scheduler no longer rescans the queue from the earliest pending event and coalesces bursts of delivery completions into a single scan.
• RocksDB:
  • Column families are tuned for the access pattern of the data they hold.
  • Range iteration uses bounded iterators and no longer reads values when only keys were requested.

Fixed

• JMAP:
  • Setting uploadTtl to 1ms triggers panic.
  • CalendarEvent/set does not assign organizerCalendarAddress nor send scheduling messages when an event is created with participants.
  • CalendarEvent/get omits isOrigin when it is listed explicitly in properties.
  • CalendarEventNotification/changes and FileNode/changes reject with cannotCalculateChanges the state that /get returned for an account with no change history.
  • CalendarEvent/set and ContactCard/set do not write a vanished tombstone for the previous CalDAV/CardDAV href when calendarIds or addressBookIds moves an item between collections.
• CalDAV: Attendee addresses that percent-encode a display name into the mailto: URI are queued verbatim.
• Calendar: Recurring events disappear from CalDAV time-range REPORTs and JMAP CalendarEvent/query results a few years after their first occurrence.
• WebDAV:
  • When a file node references a parent folder that no longer exists, any request on a file collection panics.
  • MOVE on a folder honors a Depth header of 0 or 1 instead of always moving the whole subtree.
• MTA:
  • DSN bounces are emitted with a malformed Message-ID wrapped in doubled angle brackets.
  • Delivery to any MX host whose name is an IDN A-label fails permanently.
  • Queue strategy and quota expressions that branch on source never match at enqueue.
  • MTA-STS:
    • Policies in testing mode are enforced, turning any TLS error into a permanent failure.
    • mx patterns published as U-labels never authorize the MX host they name.
  • DMARC:
    • Alignment compares identifiers in their A-label form.
    • External reporting addresses published as U-labels are rejected as unauthorized.
• Spam filter:
  • Some rules misfire on internationalized addresses when the envelope and the headers spell the same domain in different label forms.
  • Punycode labels that do not re-encode to the label they came from are no longer decoded.
• WebPush: Validate push URL and use application/octet-stream as Content-Type for encrypted payloads.
• Directory:
  • Local group membership is cleared when the external directory is configured with a group claim or attribute that it does not return.
  • LDAP: Directories that store aliases as additional values of the primary address attribute provision no aliases.
  • Mail addressed to a domain alias is rejected with 550 Relay not allowed, unless the domain's primary name happened to be resolved earlier and is still cached.
• RocksDB: bufferSize setting was applied to the unused default column family and had no effect.
• Sieve: include statements fail to find system and user global scripts whose name contains uppercase characters.
• Task manager: totalDeadline is measured from the time a task was created instead of its first failed attempt.

If you are upgrading from v0.16.x, replace the binary (or run docker pull). If you are upgrading from v0.15.x and below, please read the upgrading documentation for more information on how to upgrade from previous versions.

Added

• IMAP:
  • UIDBATCHES extension (RFC 10022).
  • UIDONLY extension (RFC 9586).
  • MESSAGELIMIT and SAVELIMIT extensions (RFC 9738).
• WebDAV: Range and If-Range header support on file downloads (RFC 7233) (#2377).
• Spam filter: url_original expression variable for Url rules.

Changed

• Memory allocator: Replaced the unmaintained jemallocator crate with tikv-jemallocator (contributed by @checkraisefold).
• ACME registry: Use description as label property.

Fixed

• MTA:
  • Certificates for domains publishing an enforcing MTA-STS policy are always validated, even in the fallback TLS strategy.
  • DSN delivery date uses wrong timestamp.
  • FUTURERELEASE HOLDUNTIL uses Unix timestamps instead of RFC 3339 date-times.
• JMAP:
  • EmailSubmission/query filtering on undoStatus contradicts EmailSubmission/get, reporting held FUTURERELEASE submissions as final instead of pending.
  • EmailSubmission/get requests without an ids argument iterates the wrong index.
• CardDAV: Accept: text/vcard version negotiation is ignored whenever another parameter such as q or charset follows version=.
• Calendar: Server-side scheduling messages place the text/calendar part outside the multipart/alternative and disposed as an attachment.
• Sharing: Accounts holding the impersonate permission never have their ACL grants collected, so shared items are never listed in JMAP sessions, CalDAV/CardDAV discovery or IMAP.
• IMAP:
  • COPY/MOVE into a shared folder fails with NO [ALREADYEXISTS] when the destination account already holds the message, leaving the message in the source mailbox and clients in a retry loop.
  • BODYSTRUCTURE and ENVELOPE return MIME parameters, Content-Description, subjects and display names as raw UTF-8 even to sessions that never enabled UTF8=ACCEPT.

New major features

General

• support forwarding streams natively (#5558) It is now possible to define forward destinations for each path configuration. For each destination, the server will create a client that will forward the stream to the intended destination. Supported protocols are RTSP, RTMP, SRT. API and metrics have also been improved to allow monitoring the new forwarding system. Documentation: https://mediamtx.org/docs/features/forward

Media-Over-QUIC

• support publishing and reading through native QUIC (#6039)
• support draft-17 (#6040)
• support draft-16 (#6045)

Fixes and improvements

General

• docs: add missing MoQ ports (#5983)
• Add OpenAPI definition of the Playback server (#5546)
• fix support for regexp groups greater than 10 (#6033)

Media-Over-QUIC

• increase max namespace field count to 32 (#6043)
• link primitives to draft-17 sections (#6044)

RTSP

• fix inability to read some AV1 streams with RTSP (#6001) (#6006) Since v1.16.0, temporal unit delimiters were not stripped from AV1 streams anymore. This has been restored, healing AV1 streams read with RTSP.
• log write errors (#6023)
• make multicast errors on single interfaces non-fatal (bluenviron/gortsplib#1115) (#5574) When writing multicast packets to several interfaces at one, a write error to a single interface was fatal and prevented writing to the other ones. Fix this.

RTMP

• server: fix parsing URL from multitrack OBS (#6007) (bluenviron/gortmplib#93)
• client: change mapping between URL and tcURL, app, streamKey (bluenviron/gortmplib#94) (#4676) URLs passed to clients are now mapped into RTMP-native fields (tcURL, app, streamKey) in this way: tcURL contains URL without credentials and without fragment, app contains path and query of tcURL, streamKey contains the fragment.
• client: fix compatibility with YouTube (#5558) (bluenviron/gortmplib#95)

HLS

• muxer: fix goroutine leak during part rotation (bluenviron/gohlslib#372) (bluenviron/gohlslib#373)
• muxer: remove lower limit on AAC access unit count in MPEG-TS segments (bluenviron/gohlslib#329) (bluenviron/gohlslib#377)
• muxer: recompute PTS of MPEG-TS AAC (bluenviron/gohlslib#379) iOS requires a precise timestamp that is often not available in AAC streams. Recompute timestamp from scratch.

WebRTC

• sort tracks in a deterministic way (#5988) (#5989) When ingesting tracks with WebRTC, track order was randomized, preventing multi-track always-available streams from working reliably, since they require tracks to be ordered in a precise way. WebRTC tracks are not ordered by MID, RID, trackID and streamID respectively.
• fix packet corruption when reading G722 (#6000)
• reset recomputed audio PTS if it drifts too much (#6021)
• fix "packet lost" error when routing streams from WebRTC (#6034) Chrome sometimes sends empty packets, that are discarded by the server, but the sequence number of following packets is not recomputed, leading downstream packet loss detectors to emit errors. This is fixed.

SRT

• improve log clarity (#5990) use message 'passphrase not provided by client' when clients do not provide passphrases.
• show stream ID in logs (#6018)
• close sources immediately when path is closed (#6038)

Dependencies

Added

• JMAP Email Delivery Push Notifications (draft-ietf-jmap-emailpush-03)
• MTA: Allow System Sieve scripts to access orcpt during the DATA stage.

Changed

• S3: accessKey can now be read from an environment variable or file.

Fixed

• Meilisearch: Verify index existence using GET instead of creating a new task which times out on busy servers.
• Branding: Stalwart logo flashes before the per-tenant logo is loaded on the login page.
• Calendar: iMIP and alarm notification messages embed the default logo using bare LF line endings, producing a single 4247 octet line that strict SMTP relays reject with line too long.
• DMARC: Failure reports state Identity-Alignment: none when a mechanism authenticated successfully but against an identity that is not aligned with the From domain.
• Redis: Task and queue locks are never released after a worker dies, because failed lock attempts refresh the lock expiry.
• Recovery mode: Download WebUI if missing.
• Logging: The systemd journal tracer omits the parent span's fields.
• MTA:
  • BDAT chunks sent without a valid MAIL FROM are answered with 552 5.3.4 Message too big for system instead of 503 5.5.1.
  • A maxMessageSize of 0 rejects every message with 552 5.3.4 Message too big for system instead of disabling the size limit.
• Windows: Listeners bound to the unspecified IPv6 address ([::]), including all defaults, refuse IPv4 connections such as 127.0.0.1, since IPV6_V6ONLY is enabled by default on Windows.

Added

Changed

Fixed

• JMAP:
  • Email/copy should return alreadyExists when copying a message to a mailbox that already contains it.
  • Email/copy with onSuccessDestroyOriginal destroys the copy's creation id instead of the source Email id.
  • CalendarEvent/set does not generate a uid on create when the client omits it.
  • CalendarEvent/set does not refresh the updated property (iCalendar DTSTAMP) on create or update.
  • EmailSubmission/set rejects valid recipients whose domain is itself a public suffix (e.g. gov.in, co.uk).
  • Requests are rejected with notRequest when a method name contains a JSON-escaped solidus (e.g. Core\/echo).
• MTA: Panic when MTA-STS is disabled and a remote MTA fetched /.well-known/mta-sts.txt.
• Auth: Scoped credentials with SysApiKeyCreate or SysApiKeyUpdate permissions can regain its own account's full rights.
• Web Push: Valid VAPID keys are rejected when PEM-encoded with explicit EC parameters, in SEC1 (EC PRIVATE KEY) format, or with a leading byte-order mark.
• Encryption at rest: Appended messages are encrypted for accounts that did not opt in to encryptOnAppend.
• Cache: Account caches silently discard entries larger than a single quick-cache shard, causing constant database rebuilds.
• Registry: Id references (e.g. #certificate-...) fail to resolve on defaultCertificateId, defaultAdminRoleIds, listenerIds and publicKey.
• Search: reindex drops calendar and contact index tasks for accounts with fewer than a full batch of items.
• Migration: Abort --import when the target already contains data in the key range being imported.
• Cluster: Broadcast subscriber re-subscribes after every message, losing bursts of cluster broadcasts during the reconnect window.
• Enterprise: Per-tenant logo is not shown on the OAuth login password and OTP screens, which are served from the server's canonical host rather than the tenant domain.

Fixes and improvements

General

• fix error message (#5922) 'all' is a synonym for 'all_others'
• fix clearing lists with environment variables (#5410) (#5924) MTX_AUTHINTERNALUSERS_0_IPS, MTX_LOGDESTINATIONS and MTX_RTSPTRANSPORTS can now be used to clear their corresponding list by setting them to an empty value.
• add runOnOnline / runOnOffline hooks (#5399) (#5956) These are triggered and a stream is online (i.e. not just provided by an offline segment).
• rename runOnReady into runOnAvailable, runOnNotReady into runOnUnavailable (#5957)
• fix wrong PTS and wrong playback of alwaysAvailableFile (#5436) (#5960) PTS offset of samples was not properly considered, and sleep between samples was PTS-based instead of being DTS-based.
• avoid potential timing attack when validating SHA256 credentials (#5961) The == operator is vulnerable to timing attacks as it short-circuits on a mismatch. Use ConstantTimeCompare to avoid this vector. Co-authored-by: Tristan Matthews tmatth@videolan.org
• normalize authentication error messages (#5421) (#5959) Log authentication errors as soon as possible, use the "warn" level, use the same message whatever the author or protocol.
• adjust code to prevent security scan false positives (#5963) about string escaping.
• ask for credentials only in case of protocols that support it (#5966) When clients connect with some protocols (SRT, RTMP), they are unable to provide credentials even if they are asked to. In this case, it's useless to wait for credentials, and it's better to immediately log authentication errors and apply the anti-brute force algorithm.
• docs: add fail2ban integration (#5016) (#5967)
• add comment to prevent security scan false positives (#5973)
• pmp4: fix support for ctts version 0 (#5436) (bluenviron/mediacommon#343)

API

• generate most of OpenAPI automatically (#5918) enums and structs are now generated automatically. This eliminates some inconsistencies and makes development easier.

Media-Over-QUIC

• fix race condition during startup (#5965) allocate the HTTP server only after the MoQ server has been initialized.
• fix several panics and OOM errors (#5964) Check for limits before allocating memory by using sizes passed from the remote peer. Also add fuzzing to all MoQ primitives.
• support draft-19 of the specification (#5968) * support draft-19 of the specification * support subscribing the same track multiple times.
• prevent excessive CPU consumption in reorderer (#5976) do not iterate by maxGroupID (passed by user) but iterate by internal pending packets (uncontrolled by user).

WebRTC

• prevent cross-origin unauthorized access (#5975) when a user had previously inserted credentials into a MediaMTX instance through a browser, and AllowOrigins was set to a wildcard, third-party websites visited by the user were allowed to read streams without restrictions. This is now prevented by returning "*" in Access-Control-Allow-Origins when AllowOrigins is a wildcard, a behavior that prevents browsers from sharing credentials with third-party websites.

RTSP

• restore support for H264 packetization-mode 0 (#5846) (#5857) H264 streams with packetization-mode=0 cannot be routed with UDP since packets are too big. Inbound streams with packetization-mode=0 are blocked by the server since v1.19.0 but this caused compatibility issues with some cameras. The server is now able to receive such streams with TCP, and automatically remuxes them in streams with packetization-mode=1, which can be routed freely.

New major features

Media-over-QUIC

• support reading and publishing with Media-over-QUIC (#5815) Media-over-QUIC is a streaming protocol built upon cutting edge protocols (QUIC, HTTP3) and browser APIs (WebTransport, WebCodecs). It's slightly faster than WebRTC, has an advanced data recovery mechanism, it supports additional codecs (FLAC) and is less complicated to route. Check the documentation for instructions and details.

RTMP

• support reading and writing FLAC (#5778) (#5789)

HLS

• support reading and publishing FLAC (#5778) (#5791)

Fixes and improvements

General

• Add user agent field to RTMP, RTSP, WebRTC, and HLS (#5753)
• add --check-version command line flag (#5786) this allows to check whether a new version is available without upgrading.
• use file name suffix for OS-specific code wherever possible (#5787)
• fix two hot reloading cases (#5817) * reload SRT server when metrics server is reloaded * reload API server when RTMPS server is reloaded

RTSP

• client: trigger TCP timeout only if nothing is received (bluenviron/gortsplib#1002) (bluenviron/gortsplib#968) (bluenviron/gortsplib#1067) Previously, a data packet was required, now a keepalive response from the server is enough.
• sdp: support non-standard 'meta' media type (bluenviron/gortsplib#1068)
• forbid H264 packetization mode zero (bluenviron/gortsplib#1072) Packetization mode zero requires allowing inefficient and brittle fragmented UDP packets, which we are not.

RTMP

• client: add FLAC fourCC (bluenviron/gortmplib#73)
• do not exit in case of undocumented Flash control messages (#5512) (bluenviron/gortmplib#75)

HLS

• remove redundant JavaScript argument (#5806)
• muxer: fix race condition when generating playlist (bluenviron/gohlslib#359) (bluenviron/gohlslib#360) Max age of playlist depends on segments, so it needs to be covered by the segment mutex.
• muxer: use coherent version in all playlists (#5781) (bluenviron/gohlslib#363)

WebRTC

• make JavaScript internal variables private (#5804)
• fix connectivity after network changes (#5097) (#5818)

Fixes and improvements

RTSP

• fix compatibility with Verint.Vms.MediaGateway (#5292) (bluenviron/gortsplib#1061)
• fix crash when stream is closing (bluenviron/gortsplib#1062) when ServerStream.Close() is called, stream readers might have their setuppedTransport set to nil, causing the server to crash. Prevent this.
• fix race condition when tearing down connection (bluenviron/gortsplib#1063) ServerConn.session was not properly protected.
• fix leak in case of failure during multicast initialization (bluenviron/gortsplib#1064)

RTMP

• prevent nil / unconfigured tracks from appearing (bluenviron/gortmplib#66) (#5724) (#5729)

HLS

• fix error 500 caused by in-stream params (bluenviron/gohlslib#355) (#5728) (#5745) PR bluenviron/gohlslib#344 caused a regression. Many codecs (AV1, H264, H265, VP9) use in-stream parameters, that were not taken into consideration anymore when generating init.mp4 and playlists. This has been solved.

WebRTC

• fix checking POST responses (#5758)
• support interacting with servers with no trickle ICE (#5273) (#5757)
• support WHIP ICE restarts (https://github.com/bluenviron/mediamtx/issues/5183) (#5770)

Fixes and improvements

General

• prevent code injection in case of MTX_QUERY in hooks (#5707) When MTX_QUERY is used explicitly in hooks, for instance "curl http://something/?$MTX_QUERY", it can be used to inject arbitrary commands. MTX_QUERY is now url-encoded to prevent any abuse regardless of the configuration.
• use temporary redirects instead of permanent redirects (#5710) this prevents unwanted caching.

HLS

• prevent open redirect attacks (#5708)
• support reading and writing KLV (#5604)
• add hlsCDNSecret (#5716) this allows to serve HLS streams behind a CDN in a simplified way, compatible with the new HLS session system.
• add public attribute to cache-control header (bluenviron/gohlslib#349)
• allow caching non-low-latency playlists (bluenviron/gohlslib#350)

WebRTC

• prevent open redirect attacks (#5708)

RPI Camera

• Merge request->controls instead of overwriting (bluenviron/mediamtx-rpicamera#97) libcamera 0.7.0 is more strict about changing controls; assignment is no longer allowed since raspberrypi/libcamera@310cd8b Instead, we use the merge call with overwrite.

New major features

HLS

• track sessions (#962) (#5683) sessions are now tracked through cookies or query parameters. This provides the ability to inspect sessions through logs, metrics and API, allows more precise tracking of outbound bytes, decreases load on external HTTP authentication URLs since they are now called once per session and not once per request.
• support serving streams with a CDN (#5696)

Fixes and improvements

General

• improve listener labels (#5635) add a label after every "listener opened on :XXX" message that mentions protocols of every listener.
• dump unencrypted TLS sessions (#5624) when dumpPackets is true, embed TLS master keys into the dump, in a format which is natively compatible with Wireshark.
• use "token" as query parameter key to pass tokens (#5647) the legacy "jwt" query parameter key is still supported.
• deprecate authJWTInHTTPQuery and disable JWTs in query parameters (#5648) This fixes a long standing security flaw. Even though it's a breaking change, few users should be impacted since this feature has been discouraged for some time.
• expose token passed as query parameter to HTTP authentication too (#5649) this allows to parse tokens coming from RTSP and RTMP without additional effort.
• playback: return errors as JSON (#5656) this is aligned with all other HTTP-based services.
• prevent out-of-memory errors (#5674) impose a maximum size on body of incoming HTTP requests and responses.
• metrics: improve performance (#5663) use string.Builder instead of string concatenation
• metrics: add labels to the output (#5687) group metrics under visible, distinct labels.
• metrics: fix filtering by type=rtmp_conns and type=rtmps_conns (#5689)
• metrics: add readerType attribute to the path_readers metric (#5690) this allows to filter path readers by type.
• metrics: use an enum for parsing metrics type (#5692)
• metrics: fix race condition when reloading configuration (#5693)
• docs: add scaling page (#5695)

API

• sort path readers (#5691)

RTSP

• client: fix RTSP-over-HTTP tunnel request target (bluenviron/gortsplib#1041)
• client: support Axis SRTP variant (bluenviron/gortsplib#1033)
• improve SDP parser compatibility with malformed connection information (bluenviron/gortsplib#1025)
• support parsing responses with no status message (bluenviron/gortsplib#1043) (bluenviron/gortsplib#1050)
• client: don't block RTSP-over-HTTP tunnel startup on POST response (bluenviron/gortsplib#1047)

HLS

• return JSON with error message in case path conf is not available (#5655) this behavior is aligned with WebRTC one.
• improve muxer performance (#5660) use a mutex instead of a channel to get current instance.
• fix running linter when there are unstaged git changes (bluenviron/gohlslib#336)
• client: use redirected URL when reloading playlist (bluenviron/gohlslib#340) this allows to store and use tokens and signed URLs.
• client: support reading KLV (bluenviron/gohlslib#337)
• prevent out-of-memory errors (bluenviron/gohlslib#343)
• muxer: generate init segment once (bluenviron/gohlslib#344) Previously, the init segment was regenerated in case of codec parameter changes, but changing the init segment has been proved to cause video and audio discontinuities on iOS. Now the init file contains starting parameters only and never changes during the stream lifetime.
• client: increase size limit of segments and parts (bluenviron/gohlslib#345)
• return a custom error when body size limit is exceeded (bluenviron/gohlslib#346)
• muxer: store non-low-latency playlists and init files on disk (bluenviron/gohlslib#348)

Fixes and improvements

General

• prevent directory traversal attacks (#5602) Path names are used as part of paths in several components: in the recorder, in the playback server and in every HTTP-based component (WebRTC, HLS, API). Special characters that allow to escape from the intended directory are now forbidden in order to prevent directory traversal attacks.

RTSP

• client: fill server name indication (SNI) of TLS connections (bluenviron/gortsplib#1038)

RTMP

• implement AbortMessage (#4673) (bluenviron/gortmplib#59)
• client: fill server name indication (SNI) of TLS connections (bluenviron/gortmplib#63)

WebRTC

• fix random absolute timestamps with Opus, G711 and LPCM (#5597) When rewriting audio RTP timestamps in WebRTC egress, NTP was derived using regenerated packet timestamps minus the incoming RTP base timestamp. That mixed timestamp domains and could shift absolute time by an arbitrary offset while still exposing mapping as available. Fix by using a consistent outgoing RTP domain in rewritten audio paths
• strip TWCC extension of incoming RTP packets (#5146) (#5605) The TWCC extension is used as part of the WebRTC congestion control algorithm placed between the publisher and the server. If this extension is routed untouched from the server to readers, it messes with the congestion control algorithm present between the server and each reader. Remove it.

New major features

WebRTC

• support publishing multiple video/audio renditions (#5573) this allows to receive multiple video tracks from OBS Studio with the new WebRTC Simulcast feature introduced in v32.1.0.

API

• provide track details (#5307) (#5333) (#1726) (#5585)
• add user field to RTSP, RTMP, SRT, WebRTC conns and sessions (https://github.com/bluenviron/mediamtx/issues/5104) (#5565)
• add RTSP reported lost packets (#5198) (#5579) The new outboundRtpPacketsReportedLost property allows to track RTP packets that have been reported lost by readers. Furthermore, stats now have a "inbound" or "outbound" prefix to improve readability.
• rename WebRTC stats to match RTSP ones (#5581)
• add new stats (#5582) - RTSPSession.outboundRTPPacketsDiscarded - Path.inboundFramesInError - SRTConn.outboundFramesDiscarded - WebRTCSession.outboundFramesDiscarded - RTMPConn.outboundFramesDiscarded - HLSMuxer.outboundFramesDiscarded

Fixes and improvements

General

• avoid buffering HTTP response body in loggerWriter (#5552) loggerWriter was shadow-copying every response byte into a bytes.Buffer to report the body size, causing the entire response to be accumulated in memory for the lifetime of each request. Replace the buffer with a plain int counter since dump() only ever reported the byte count anyway.
• optionally validate JWT iss and aud claims (#5569)
• metrics: add two missing SRT stats (#5580)

API

• add deprecated fields to the OpenAPI definition (#5575)
• add missing enums and move all enums in dedicated components (#5576)

RTSP

• fix rtsps scheme not being used in requests (#5236) (#5544)
• support unwrapping MPEG-TS tracks (#5476) this allows to use MPEG-TS tracks with other protocols and with the recording system
• client: fix support for hostnames in source and dest headers (bluenviron/gortsplib#1009) (#5304) (bluenviron/gortsplib#1014)
• allocate a rtp sender for each server session (bluenviron/gortsplib#1021) this produces more realistic statistics and in the future will allow to implement per-session statistics and packet retransmission.
• store reported lost RTP packets in stats (#5198) (bluenviron/gortsplib#1023)

HLS

• muxer: support muxing KLS with MPEG-TS (bluenviron/gohlslib#327)
• client: fix deadlock when processing fMP4s (bluenviron/gohlslib#333) (bluenviron/gohlslib#334)

• fix MPEG-4 audio configuration not matching error (#5468) (#5533) This happened when using alwaysAvailableFile and a MPEG-4 audio track.
• fix corrupted video with alwaysAvailableFile (#5534) when alwaysAvailableFile points to a file with a H265 or H264 track, server is started, an online stream is published and then closed, video was getting corrupted since the online video was overriding the parameters of the offline video.
• fix audio from alwaysAvailableFile not being streamed (#5535)
• fix alwaysAvailableFile restarting when a publisher fails (#5536) when a publisher try to start an online stream and there's an error, alwaysAvailableFile restarted without any reason.
• revert to Go 1.25 (#5521) (#5538) It seems like Go 1.26 is causing segmentation faults, related to channels, on Windows.
• inherit MPEG-4 audio type from alwaysAvailableFile (#5539)
• mpegts: properly compute PTS of async KLV frames (bluenviron/mediacommon#291) (bluenviron/mediacommon#311) Store last valid PTS as soon as possible, by parsing PES headers in advance, then use this PTS as timestamp of KLV frames without PTS.

Fixes and improvements

General

• support X-Forwarded-Proto in playback server (#4970) (#5445) allow reverse proxies to change the schema of URLs returned by the server through the X-Forwarded-Proto header.
• make config file YAML 1.2 compliant (#5345) (#5456)
• replace YAML parser (#5461) switch from the unmaintained gopkg.in/yaml to goccy/go-yaml
• deprecate unix+rtp (#5318) (#4999) (#5351) (#5470) Unix socket are stream-based connections, while RTP requires packet-based connections. While packet-based Unix sockets exist (unixgram), no client supports them. Consequently we are forced to deprecate unix+rtp.
• fix codec parameters not being loaded from alwaysAvailableFile (#5484)
• warn when alwaysAvailableFile is not MP4 (#5483)
• suggest using JWTs in query parameters for RTSP and RTMP (#5267) (#5493) In case of RTSP and RTMP, JWTs cannot be used as passwords since there's a size limit. Therefore, documentation is updated to suggest passing JWT through query parameters, and authJWTInHTTPQuery is updated to act on HTTP requests only.
• fix error 400 with parallel describe and publish requests (#5095) (#5502) When a path is dynamic, and the path receives multiple describe and publish requests in parallel, describe requests might cause the path to be deleted, and this might cause pending publish requests to fail, since the path has been deleted. This patch improves the situation by checking for pending requests before deleting a path.
• add integrated packet dumper (#5488) this allows to dump any incoming and outgoing packet, to disk, in pcapng format.
• log packet sizes if UDPMaxPayloadSize is exceeded (#4668)
• improve video/audio sync of alwaysAvailable (#5443) (#5508) store elapsed time once for the entire stream and start PTS of sub streams from there.
• improve pmp4 and fmp4 parser robustness (bluenviron/mediacommon#299)
• mp4: fix H265 + iOS compatibility (bluenviron/mediacommon#290) On iOS, H265 requires the hvc1 box instead of the hev1 box.
• h264: prevent Annex-B from decoding more NALUs than MaxNALUsPerAccessUnit (bluenviron/mediacommon#303)
• improve H264 and MPEG-4 video performance (#4971) (bluenviron/mediacommon#304)
• mp4: fill reserved fields properly (bluenviron/mediacommon#307)
• mpegts: parse Opus channel configuration (#5002) (bluenviron/mediacommon#309)

API

• add conns to RTSP Sessions (#5454) this allows to find connections associated with a RTSP session.

RTMP

• prevent legacy clients from reading multiple video/audio tracks (#5478)
• fix marshaling H264 VideoExCodedFrames (#4996) (bluenviron/gortmplib#46) These messages were marshaled wrongly, causing errors when trying to read H264 tracks with an ID >= 1.
• support reading H265 with video codec id 12 (#5105) (bluenviron/gortmplib#48)

HLS

Security

Binaries are compiled from source code by the Release workflow without human intervention.

You can verify that binaries have been produced by the workflow by using GitHub Attestations:

ls mediamtx_* | xargs -L1 gh attestation verify --repo bluenviron/mediamtx

You can verify checksums of binaries by downloading checksums.sha256 and running:

cat checksums.sha256 | grep "$(ls mediamtx_*)" | sha256sum --check
