I am trying to play back mp4 video (venerable Big Buck Bunny at this time) on RPi3.

I added gstreamer1.0, gstreamer1.0-omx and the plugins to the image.

libgstomx.so is installed in usr/lib/gstreamer-1.0 on target.

However, gst-inspect-1.0 | grep omx does not return any results.

Consequently,

gst-launch-1.0  filesrc location="/home/root/kiosk/kiosk/videos/bunny.mp4" ! qtdemux ! h264parse ! omxh264dec ! kmssink
WARNING: erroneous pipeline: no element "omxh264dec"

I guess I am missing something somewhere but I don't know what.

Thanks,
Rudi
