Hello,
I am trying to stream the video as AVTP packets using video.mp4 file stored in a memory as source. I want to send the AVTP packets at 33 ms interval (considering 30 fps rate). My pipeline is as below,
Interface=eth0.129
VideoFile=/home/pi/project/video/H264_NAL/testimages_1600kbps.mp4
StreamID=0x0402010300004001gst-launch-1.0 clockselect. (clock-id=tai
filesrc location=$VideoFile ! qtdemux ! h264parse ! decodebin !
videoconvert ! videoscale ! videorate ! video/x-raw,framerate=30/1 ! autovideoconvert !
avtpcvfpay processing-deadline=20000000 mtt=2000000 tu=125000 streamid=$StreamID !
avtpsink ifname=$Interface address=02:00:00:00:00:80 priority=3 processing-deadline=20000000 )
The video file information from the discoverer tool is as follows,

After running this on raspberry pi 4, I am facing below error,
Setting pipeline to PAUSED …
Pipeline is PREROLLING …

If I use below pipeline then I can atleast play the input,
gst-launch-1.0 -v filesrc location=$VideoFile ! qtdemux ! h264parse ! decodebin !
videoconvert ! videoscale ! videorate ! video/x-raw,framerate=30/1 ! autovideoconvert ! autovideosink
Not sure what goes wrong after I replace autovideosink with avtpsink.
Your help is highly appreciated !
