Hello all,
I have never compiled FFmpeg and have zero knowledge nor experience with the process; I use 32bit FFmpeg version 4.1.6 on a 32bit raspberry pi, I wanted to use h264_v4l2m2m for hardware-accelerated encoding using 64 bit FFmpeg v4.3 instead of the 32bit h264_omx, my steps were as follow:
I updated the PI to 64bit, now running:
Linux Dev 5.4.79-v8+ #1373 SMP PREEMPT Mon Nov 23 13:32:41 GMT 2020 aarch64 GNU/Linux
I then cloned the FFmpeg:
git clone --depth 1 --branch release/4.3 https://github.com/FFmpeg/FFmpeg.git
and lastly, I have configured and ran the script with the following parameters:
sudo ./configure --prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --extra-libs="-lpthread -lm" --bindir="$HOME/bin" --enable-gpl --enable-gnutls --enable-libaom --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree --arch=aarch64 --enable-libxml2 --enable-libwebp --enable-libdrm

What is it that I miss in the process that prevents the make from running without those errors?
Thank you all in advance!
