Restreaming Live stream

[rtspuser]

Hi,
I use libvlc to restream a live mjpeg stream using rtsp broadcast. My client is live555 proxyserver. The live555 proxy client sends play and receives video feed but after about 60 secs receives RTCP bye message. Now the input is not a file but live stream itself. I have tried --sout-keep, gather and loop enabled. It seems that RTSP session timeout is hardcoded to 60 secs and no way i can change that. The VLC RTSP server does support GET_PARAMETER and PAUSE as shown in OPTIONS. But when live555 sends it a GET_PARAMETER the response is a 451 client error and on sending PAUSE sends backs 405 error. Fyi, I use LIVE555 proxy server to tunnel over http as VLC doesnt support it yet at the server end.

libvlc_vlm_add_broadcast(VLC.Instance, "STREAM 1","http://10.0.0.23:8084","#gather:transcode{venc=x264{keyint=60,profile=baseline,level=3.0,no-cabac,vbv-maxrate=2000},vcodec=x264,vb=2000,scale=1}:rtp{sdp= ":5554/test.sdp"}",
0,null, 1, 1, ref ex);
Thread.Sleep(1000);
libvlc_vlm_play_media(VLC.Instance, "STREAM 1", ref ex);

Those are not vlc logs

[rtspuser]

How do i capture logs since i use libvlc and if I'm not mistaken libvlc logging is not supported in latest releases.

[Jean-Baptiste Kempf]

Run the app from the command line.

It seems that this particular line in rtsp.c under modules/stream out is causing an issue for me, didn't quite understand its purpose here. Is there a way my live555 client can avoid this by formatting the GET_PARAMETER in a different way and not get a 451 error. Thanks

Code: Select all

case HTTPD_MSG_GETPARAMETER: if( query->i_body > 0 ) { answer->i_status = 451; break; }

Similar problem here. I use VLC as rtsp server, and live555 proxyserver to proxy the rtsp stream. From the log generated by live555 proxyserver, every about 20s, VLC will send a "BYE" signal to live555 proxyserver, this will cause the rtsp proxy process broken.

I still can't figure out why VLC send "BYE" signal to its client
