New major features

WebRTC

• support publishing multiple video/audio renditions (https://github.com/bluenviron/mediamtx/issues/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 (https://github.com/bluenviron/mediamtx/issues/5307) (https://github.com/bluenviron/mediamtx/issues/5333) (https://github.com/bluenviron/mediamtx/issues/1726) (https://github.com/bluenviron/mediamtx/issues/5585)
• add user field to RTSP, RTMP, SRT, WebRTC conns and sessions (https://github.com/bluenviron/mediamtx/issues/5104) (https://github.com/bluenviron/mediamtx/issues/5565)
• add RTSP reported lost packets (https://github.com/bluenviron/mediamtx/issues/5198) (https://github.com/bluenviron/mediamtx/issues/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 (https://github.com/bluenviron/mediamtx/issues/5581)
• add new stats (https://github.com/bluenviron/mediamtx/issues/5582) - RTSPSession.outboundRTPPacketsDiscarded - Path.inboundFramesInError - SRTConn.outboundFramesDiscarded - WebRTCSession.outboundFramesDiscarded - RTMPConn.outboundFramesDiscarded - HLSMuxer.outboundFramesDiscarded

Fixes and improvements

General

• avoid buffering HTTP response body in loggerWriter (https://github.com/bluenviron/mediamtx/issues/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 (https://github.com/bluenviron/mediamtx/issues/5569)
• metrics: add two missing SRT stats (https://github.com/bluenviron/mediamtx/issues/5580)

API

• add deprecated fields to the OpenAPI definition (https://github.com/bluenviron/mediamtx/issues/5575)
• add missing enums and move all enums in dedicated components (https://github.com/bluenviron/mediamtx/issues/5576)

RTSP

• fix rtsps scheme not being used in requests (https://github.com/bluenviron/mediamtx/issues/5236) (https://github.com/bluenviron/mediamtx/issues/5544)
• support unwrapping MPEG-TS tracks (https://github.com/bluenviron/mediamtx/issues/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 (https://github.com/bluenviron/gortsplib/issues/1009) (https://github.com/bluenviron/mediamtx/issues/5304) (https://github.com/bluenviron/gortsplib/issues/1014)
• allocate a rtp sender for each server session (https://github.com/bluenviron/gortsplib/issues/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 (https://github.com/bluenviron/mediamtx/issues/5198) (https://github.com/bluenviron/gortsplib/issues/1023)

HLS

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

WebRTC

• fix panic with WHIP POST authentication failures (https://github.com/bluenviron/mediamtx/issues/5566)

Security

Binaries are compiled from source code by the Release workflow, which is a fully-visible process that prevents any change or external interference in produced artifacts.

Checksums of binaries are also published in a public blockchain by using GitHub Attestations, and they can be verified by running:

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
