SimpleRtspPlayer has no sound, what is the reason?

Doyle-net commented 5 years ago

I pull the source demo code, and there is no sound when playing RTSP stream after compiling. But playing RTSP streams with VLC is correct

Hi, sound player is not implemented

Hi,BogdanovKirill But I did not receive the audio stream when debugging the source code. ` private void OnFrameReceived(object sender, RawFrame rawFrame) { if (!(rawFrame is RawAudioFrame rawAudioFrame)) return;

        FFmpegAudioDecoder decoder = GetDecoderForFrame(rawAudioFrame);
        if (!decoder.TryDecode(rawAudioFrame))
            return;

        IDecodedAudioFrame decodedFrame = decoder.GetDecodedFrame(new AudioConversionParameters() {OutBitsPerSample = 16});
        FrameReceived?.Invoke(this, decodedFrame);
    }`

@Doyle-net Please debug sources by yourself or give me access to your RTSP server

Hi,BogdanovKirill I tested this address source (rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov) and it has audio. But I did not receive the audio stream by setting up the RTSP stream with VLC, but it is normal for me to play with VLC.

In "ConnectAsync" "parser.Parse(describeResponse.ResponseBody)" was not received, parsed into audio

ResponseBody： v=0 o=- 16196963941712269368 16196963941712269368 IN IP4 DESKTOP-CUMSTFP s=Unnamed i=N/A c=IN IP4 0.0.0.0 t=0 0 a=tool:vlc 3.0.7.1 a=recvonly a=type:broadcast a=charset:UTF-8 a=control:rtsp://127.0.0.1:8554/vlc m=audio 0 RTP/AVP 96 b=RR:0 a=rtpmap:96 mpeg4-generic/44100/2 a=fmtp:96 streamtype=5; profile-level-id=15; mode=AAC-hbr; config=1210; SizeLength=13; IndexLength=3; IndexDeltaLength=3; Profile=1; a=control:rtsp://127.0.0.1:8554/vlc/trackID=0 m=video 0 RTP/AVP 96 b=AS:1947 b=RR:0 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1;profile-level-id=64001f;sprop-parameter-sets=Z2QAH6wkiAUAW7ARAAADAAEAAAMAMI8YMqA=,aO4yyLA=; a=control:rtsp://127.0.0.1:8554/vlc/trackID=1

I found the reason, the audio is lost when parsing in "SdpParser" Lead to problems m=audio 0 RTP/AVP 96 m=video 0 RTP/AVP 96 “96” repeat How can I solve it?
