Multiple channel identification when frame is receeived

Hello!

Is there any way to handle if two audio channel are in the stream? It is ok, that the sdp file handles it if the dynamic payload type is different. But when I receive the frame for example RawAACFrame in the rtspClient.FrameReceived += (sender, frame) => method I can’t get the channel id so in that case I don’t know where it comes from.

Thanks!

Hello!

I have made it locally. Can I get a branch to commit it and you will check it?

Thanks!

Temporary in my code that use Dimigergo/RTSPClientSharp with the “mediaId” in upper level I have made it similar to your suggestion, and I haven’t got any performance issue with it.

I have made a class which made from hardcoded code. new CMediaInfo(1, 25) It’s only contains FPS, because I only need it.

    public class CMediaInfo
    {
        public int MediaId { get; set; }
        public int FPS { get; set; }

        public CMediaInfo(int mediaId, int fps)
        {
            this.MediaId = mediaId;
            this.FPS = fps;
        }

        public override string ToString()
        {
            return "MediaId: " + this.MediaId.ToString() 
                + " FPS: " + this.FPS.ToString();
        }
    }

When the first RawFrame is received with a MediaId I query this CMediaInfo reference from a private list and initialize my code with the saved FPS.

So according to your suggestion if these media info class come from the RtspClient class and filled from SDP the performance is the same as mine with the hardcoded temporary CMediaInfo list.

In my opinion your suggsestion is a good solution. 😃 I think it is good if every media line creates a new instance with a string list, which contains the attribute lines, and referenced in the frames. In this case I think don’t need to parse every line (FPS etc.), it should make in upper level if need.
