rtspsrc to v4l2sink

[Russell]

Hi,

I am trying to read from an rtsp stream, and write it to a loopback device
created by umlaeute/v4l2loopback <https://github.com/umlaeute/v4l2loopback>.
The command I run is:

gst-launch-1.0 rtspsrc location=rtsp://
192.168.100.211:554/ISAPI/streaming/channels/101?auth=YWRtaW46MTIzNDU= !
v4l2sink device=/dev/video1

And it prints this error message:

ERROR: from element
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc1: Internal data
flow error.

I can do the same by ffmpeg, and it works ok:
ffmpeg -i rtsp://
192.168.100.211:554/ISAPI/streaming/channels/101?auth=YWRtaW46MTIzNDU= -f
v4l2 /dev/video1

It is quite possible that I missed some elements before the v4l2sink, I
just don't know what they are. Is there anyone can help? any online tourial
regarding Gstreamer video processing (demuxer, muxer, encode, decode, etc)
is appreciated.


Thanks,
Russell
