[vlc-devel] Switch OFF reconnecting in RTSP over HTTP

[Jan Olszak]

The problem seems to be here in the continueAfterOPTIONS function - it
doesn't take into consideration we are using RTSP over HTTP.

Live555 passes an error from the HTTP GET request and VLC interprets as an
error from RTSP OPTIONS request.

Here's the function.

static void continueAfterOPTIONS( RTSPClient* client, int result_code,
                                  char* result_string )
{
    RTSPClientVlc *client_vlc = static_cast<RTSPClientVlc *> (client);
    demux_sys_t *p_sys = client_vlc->p_sys;
    p_sys->b_get_param =
      // If OPTIONS fails, assume GET_PARAMETER is not supported but
      // still continue on with the stream.  Some servers (foscam)
      // return 501/not implemented for OPTIONS.
      result_code == 0
      && result_string != NULL
      && strstr( result_string, "GET_PARAMETER" ) != NULL;
    client->sendDescribeCommand( continueAfterDESCRIBE );
    delete[] result_string;
}


Cheers,
Jan
