python3-av binary package in Ubuntu Mantic riscv64

 PyAV is a Pythonic binding for the FFmpeg libraries,
 aiming to provide all of the power and control
 of the underlying library,
 but manage the gritty details as much as possible.
 .
 PyAV is for direct and precise access
 to your media via containers, streams, packets, codecs, and frames.
 It exposes a few transformations of that data,
 and helps you get your data to/from other packages
 (e.g. Numpy and Pillow).
