uvcsink using arbitrary sources

[Markus Fritsche]

Hello,

I have a Raspberry Pi Zero 2 W set up as an USB gadget. This is recognized on my host correctly as

ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture

        [0]: 'YUYV' (YUYV 4:2:2)
                Size: Discrete 640x360
                        Interval: Discrete 0.010s (100.000 fps)
                        Interval: Discrete 0.067s (15.000 fps)
                        Interval: Discrete 0.500s (2.000 fps)

If I start the pipeline

gst-launch-1.0 videotestsrc ! queue ! uvcsink v4l2sink::device=/dev/video0

on the RPI and then open the UVC device on my host, I can see the test video just fine. However, if I start

gst-launch-1.0v4l2src  ! video/x-raw,width=640,height=360 ! tee name="local"! queue ! jpegenc ! rtpjpegpay ! udpsink host=192.168.88.51 port= 5000

on my host and

gst-launch-1.0 udpsrc port=5000 ! application/x-rtp, encoding-name=JPEG, payload=26 ! rtpjpegdepay ! queue ! jpegdec ! uvcsink v4l2sink::device=/dev/video0

on the rpi, the run time counter on the rpi just stops (no other error is being printed) and vlc on my host cannot open the video stream.

Is this supposed to work?

What additional info should I provide?


Best regards,

   Markus
