Hardware video codec

When I do this:
ffmpeg -benchmark -c:v h264_rkmpp -i file.mp4 -f null -
CPU clock speed stays at 408 MHz.

When I do this (omit -c:v h264_rkmpp):
ffmpeg -benchmark -i file.mp4 -f null -
CPU clock speed jumps to 2 GHz.

And it looks like VLC will play like the last one.
Do we need a custom compile of FFMPEG, VLC, or both?

The video doesn't play with the h264_rkmpp codec specified. ffmpeg stops with

Code:
Unknown decoder 'h264_rkmpp'


When I play the video fullscreen with mpv, clock speed jumps between 600MHz and 1.2 GHz

Did you build your ffmpeg on your own or did you use the one which comes with the Default Debian Mate  image?
