- Introduced a new RTSP relay server that allows WHIP streams to be served over RTSP.
- Added `RTSPRelayAddr` configuration option to enable the RTSP relay.
- Implemented methods for updating codec parameters and forwarding RTP packets to RTSP clients.
- Enhanced the WHIP server to handle RTSP connections and manage multiple clients.
- Added comprehensive tests for RTSP relay functionality, including OPTIONS, DESCRIBE, SETUP, PLAY, and TEARDOWN requests.
- Introduced a new Dockerfile for building the WHIP server with Go and FFmpeg.
- Implemented the WHIPHandler for managing WHIP publish sessions and generating URLs for clients.
- Added pionProvider for handling WebRTC sessions using the pion/webrtc library.
- Created the main WHIP server logic to handle SDP offers and manage active publishing streams.
- Implemented HTTP handlers for publishing, deleting, and retrieving stream information.
- Added support for SDP generation for FFmpeg consumption.
1. Allow variables in placeholders for parameter values, e.g.
{rtmp,name=$processid}. The variable starts with a $ letter.
The recognized variables are provided with the Replace func.
2. The template func recieves the process config and the name of
the section where this placeholder is located, i.e. "global",
"input", or "output".
If a process has some cleanup with purge-on-delete defined, the purge
has to wait until the process actually exited. Otherwise it may happen
that the process got the signal, files are purged, but the process is
still writing some files in order to exit cleanly. This would lead to
some artefacts left on the filesystem.
For the API endpoint /v3/process two new query parameter are introduced
in order to list only processes that match a pattern for the id and the
reference: idpattern and refpattern. The pattern is a glob pattern. If
patterns for both are given, the results will be intersected. If you use
other query parameters such as id or reference, they will be applied
after the result of the pattern matching.
If a value for a placeholder needs escaping, add the character to
escape with an "^" to the name of the placeholder, e.g. {memfs^:}.
This will escape all occurences of ":" in the value for {memfs}
with a "\".
If PUT /process/:id is called in order to replace an existing
process config with an invalid process config, the existing
process was deleted and an 409 was returned. A subsequent GET on
the previous process would then return a 404, which is not
what you expect. The previous process needs to stay in place.
