RTP/RTSP Disconnect on IP camera

Trying to play the RTP/RTSP h264 video stream from an IP camera.

VLC works but gstreamer does not. I have narrowed it down to the camera seems
to be misrepresenting its capabilities and VLC continues while
gstreamer errors out
and resets the tcp connection when the second SETUP fails.

How do I tell gstreamer to ignore the camera response and only play
the video stream?

Re: [gmail] RTP/RTSP Disconnect on IP camera

> Trying to play the RTP/RTSP h264 video stream from an IP camera.

1/ specify the make and model of the IP camera: most of them have their
own quirks.

2/ see what happens with

gst-launch rtspsrc location=rtsp://... debug=1 ! decodebin2 ! autovideosink
