RTSP stream to webrtcbin

[Ottawa Boy]

Hi Matt,

Thanks for your reply. I tried the following pipeline as per your
suggestion but the video still continues to allude me.

gst_parse_launch("rtspsrc location=rtsp://10.51.52.115/h264 ! rtph264depay
! rtph264pay ! application/x-rtp,media=video,encoding-name=H264,payload=96
! webrtcbin name=sendrecv", &error);

I also tried replacing rtspsrc with urisourcebin but that hasn't worked
either.

gst_parse_launch("urisourcebin uri=rtsp://10.51.52.115/h264 ! rtph264depay
! rtph264pay ! application/x-rtp,media=video,encoding-name=H264,payload=96
! webrtcbin name=sendrecv", &error);

Do both of these pipelines look reasonable? Perhaps I missed some
intermediate element/plugin.

The only way that I have managed to get video is to decode the H264 frames
and re-encode them in H264 format, which is redundant and undesirable.

gst_parse_launch("rtspsrc location=rtsp://10.51.52.115/h264 ! rtph264depay
! h264parse ! decodebin ! videoconvert ! queue ! x264enc ! rtph264pay !
queue ! application/x-rtp,media=video,encoding-name=H264,payload=96 !
webrtcbin name=sendrecv", &error);

Thanks!
Talha
