In Kodi it is simple, just press the O key.

The CPU usage is a very good indication and this is ultimately why you use hwaccel…

There should be a lot of v4l2-request info in the debug output.

At the moment I cannot try myself to check my output

Try something like this:

ffmpeg -loglevel debug -hwaccel drm -hwaccel_output_format drm_prime -i journal.ts -f null /dev/null

I think I remember you also need to add -hwaccel_output_format to enable v4l2-request.

Edit:

Does it work now?

Actually, for newest ffmpeg v4l2-request, it (already) has 4.4.1, so use this instead:

git clone https://github.com/jernejsk/FFmpeg
git checkout v4l2-request-hwaccel-4.4.1-Nexus-Alpha1
git merge --no-edit v4l2-drmprime-v6-4.4.1-Nexus-Alpha1

Yes it works for ffmpeg command-line, thanks. Had no time to build and check kodi.

Btw, is merging the drmprime branch a mandatory? what is the functionality there?

Yes it is, you need the output format to handle the buffers output directly in memory.
