I have managed to build FFmpeg with Cedrus on Armbian and it seems working.
It would be nice to see some benchs and how would be the best use for this AW Encoder.
I have not much experience with FFmpeg.
You can test it:
To grab video stream from the CMOS camera:
sudo ./ffmpeg -f v4l2 -channel 0 -video_size 640x480 -i /dev/video0 -pix_fmt nv12 -r 30 -b:v 64k -c:v cedrus264 test.mp4
