I can’t find my answer in older posts on this forum : is the FFMPEG version available in hass.io compiled with GPU hardware acceleration options turned-on, i.e. either MMAL or OpenMAX (OMX) or both? This is not clear from the dedicated page.
If neither MMAL nor OMX are activated in the ffmpeg binary provided with hass.io, is it possible to delete that provided version located at /usr/bin/ffmpeg then download source and finally compile our own version of ffmpeg with the appropriate option-arguments, directly in hass.io?
This community really lacks some HA developers answering around and helping its users…
Many topics like this finish down the tubes with people asking for help in the void. This is very sad.
Also, the random “You were logged out” from this board when you are typing a lengthy message really pisses me off.
Self-answer:
the ffmpeg version in hass.io is not compiled with GPU acceleration.
it is not possible to compile ffmpeg from source in hass.io, whatever the container you’ve ssh into (user or system).
Solution: I erased the SD card and installed Hassbian instead. I compiled latest ffmpeg with appropriate flags there.
Not received by USB cam yet, but will make tests with either vaapi, omx and mmal.
It seems that developers are only available on discord which makes finding solutions on the forum a lot harder as many of the discussed solutions don’t ever appear here.
