The state of mainline hardware decoding
#12
The example you posted doesn't decode the stream at all. It stream copies the mjpeg into an mp4 container. This is not a valid way to test whether you are hardware decoding.

What you want is something like

ffmpeg -i video.mp4 -hwaccel drm -f null -

This will decode the intput video.mp4 with the hwaccel, and just throw away the output (decoded) data. (note the - at the end, that's required)
