OK @crackwitz, I saw the avresample line in the log.
After:
sudo apt-get install libavresample-dev
I’ve got a YES at the end of the line of “avresample” in the log, but I still have a NO on FFMPEG.
I try to find a way to install libmmal_core in a static way (libmmal_core.a) but I only have the .so one and I am not able to find a way to install the .a file …
