This is a fork of ffmpeg that adds supports wz265 and nvv4l2 against ffmpeg 4.3.3.
wz265 support is taken from release V1.3.5.0-1-gf25103c
nvv4l2 support is taken from https://gitlab.com/switchroot/switch-l4t-multimedia/FFmpeg/-/tree/1d0dbfb7243a12b2941a23584a2dbed7cfb7077f
Compiling for the jetson nano is a bit annoying so build.nvidia is a precompiled version.
