Question - server example

[spawn451]

Based on gortsplib/examples/server/main.go is there a way to allow multiple client to publish a stream instead of a single one ?

Hello, if you want to support multiple streams, you have to save those streams somewhere, index them by some parameter (for instance, the path name) and serve them by using this chosen parameter, like was done in MediaMTX.

Example:

// called when receiving an ANNOUNCE request.
func (sh *serverHandler) OnAnnounce(ctx *gortsplib.ServerHandlerOnAnnounceCtx) (*base.Response, error) {
	log.Printf("announce request")

	sh.mutex.Lock()
	defer sh.mutex.Unlock()

	stream, ok := sh.streams[ctx.Path]

	// disconnect existing publisher
	if ok {
		sh.stream.Close()
		sh.publishers[ctx.Path].Close()
	}

	// create the stream and save the publisher
	sh.streams[ctx.Path] = gortsplib.NewServerStream(sh.s, ctx.Description)
	sh.publishers[ctx.Path] = ctx.Session

	return &base.Response{
		StatusCode: base.StatusOK,
	}, nil
}

where streams and publishers are respectively a map[string]*gortsplib.ServerStream and map[string]*gortsplib.ServerSession.
