Using sources from LE, I built a version of FFMPEG with support for hardware decoder v4l2-m2m.

When install the package on Armbian version 20181205 with kernel 4.19.6, i’m run a test check.
ffmpeg -c:v h264_v4l2m2m -i Test.mp4 -f null /dev/null
The system shows that the decoding in FFMPEG is working.
I tried to perform a decoding check using GStreamer using this instruction.
gst-launch-1.0 filesrc location=Test.mp4 ! matroskademux !
h264parse ! v4l2h264dec ! videoconvert n-threads=4 ! kmssink
driver-name=meson force-modesetting=true connector-id=29 sync=false
But I receive an error. Maybe I’m doing something wrong or now I need to use other options ?
