FFMPEG BENCHMARK 
----------------

git clone https://github.com/FFmpeg/FFmpeg 
cd FFmpeg 
./configure 
make -j8 
sudo make install 



TL;DR 
-----

ffmpeg-current from git is optimized for riscv64 and encoding a video is roughly 20x slower on DC-ROMA II Pad than on M2 MacBook Air (arm64) 
Still the best current performance is from the latest git cloned ffmpeg on the riscv64   

COMMMAND 
--------

ffmpeg -benchmark -i input.mp4 output.mp4
