Trying to get video/x-raw from rtsp stream

[Jim Ruxton]

I am running gstreamer in Ubuntu 19.10 and having troubles getting a pipeline to work.
This pipeline :

gst-launch-1.0 videotestsrc ! v4l2sink device=/dev/video2

works as expected and sends the videotestsrc to my /dev/video2 device however I want to send a rtsp stream to /dev/video2.

I have tried the following which I expected to work but it doesn't work.

gst-launch-1.0 rtspsrc location=<a class="moz-txt-link-freetext" href="rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa">rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa ! decodebin ! videoconvert ! video/x-raw,width=640,height=480,format=RGB ! v4l2sink device=/dev/video2

Output of the command is:

Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Progress: (open) Opening Stream Progress: (connect) Connecting to <a class="moz-txt-link-freetext" href="rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa">rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa Progress: (open) Retrieving server options Progress: (open) Retrieving media info Progress: (request) SETUP stream 0 Progress: (open) Opened Stream Setting pipeline to PLAYING ... New clock: GstSystemClock Progress: (request) Sending PLAY request Progress: (request) Sending PLAY request Progress: (request) Sent PLAY request Got context from element 'vaapipostproc0': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayX11\)\ gldisplayx11-0"; Got context from element 'vaapipostproc0': gst.vaapi.Display=context, gst.vaapi.Display=(GstVaapiDisplay)"\(GstVaapiDisplayDRM\)\ vaapidisplaydrm1";


How can I get the same video/x-raw output format from rtspsrc as I did from videotestsrc? I would really appreciate any pointers. I have tried a bunch of things with no good results.
Thanks,
Jim

Hi,

I think you need to use rtspclientsync to send media to rstp.

I use this for audio:

gst-launch-1.0  filesrc location=ogg.ogg ! oggdemux ! rtspclientsink
do-timestamp=1 debug=true latency=0
location=rtsp://127.0.0.1:8554/test/record

Thanks  Eric. In my case rtsp is my source not my sync.  /dev/video2 is my sink.

Following up on this I got the rtstp stream into /dev/video2 to work using this pipeline:

gst-launch-1.0 rtspsrc location=<a class="moz-txt-link-freetext" href="rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa">rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa ! rtph264depay ! avdec_h264 ! decodebin ! videoconvert ! "video/x-raw,format=YUY2" ! v4l2sink device=/dev/video2
