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: - snapshot outgoing base timestamp before rewriting each unit - compute NTP from (outgoing packet timestamp - outgoing base timestamp) This keeps RTP<->NTP mapping coherent for sender reports and prevents random absolute-time offsets in WebRTC loopback with useAbsoluteTimestamp. --------- Co-authored-by: aler9 <46489434+aler9@users.noreply.github.com>
MediaMTX is a ready-to-use and zero-dependency real-time media server and media proxy that allows to publish, read, proxy, record and playback video and audio streams. It has been conceived as a "media router" that routes media streams from one end to the other, with a focus on efficiency and portability.
Features
- Publish live streams to the server with SRT, WebRTC, RTSP, RTMP, HLS, MPEG-TS, RTP, using FFmpeg, GStreamer, OBS Studio, Python , Golang, Unity, web browsers, Raspberry Pi Cameras and more.
- Read live streams from the server with SRT, WebRTC, RTSP, RTMP, HLS, using FFmpeg, GStreamer, VLC, OBS Studio, Python , Golang, Unity, web browsers and more.
- Streams are automatically converted from a protocol to another
- Serve several streams at once in separate paths
- Reload the configuration without disconnecting existing clients (hot reloading)
- Serve always-available streams even when the publisher is offline
- Record streams to disk in fMP4 or MPEG-TS format
- Playback recorded streams
- Authenticate users with internal, HTTP or JWT authentication
- Forward streams to other servers
- Proxy requests to other servers
- Control the server through the Control API
- Extract metrics from the server in a Prometheus-compatible format
- Monitor performance to investigate CPU and RAM consumption
- Run hooks (external commands) when clients connect, disconnect, read or publish streams
- Compatible with Linux, Windows and macOS, does not require any dependency or interpreter, it's a single executable
- ...and many others.
