@th0ma7 I'm not sure if this is of interest to you.
If you have the time, why don't we have --enable-vaapi --enable-encoder=h264_vaapi in synocommunity's ffmpeg?

on x86_64 you have the following which includes --enable-vaapi:

And you do have h264_vaapi:

...

Thanks, stupid me not checking encoders 😆

well, ffmpeg is a beast... ;)
