libavutil58 binary package in openKylin Nile V2.0 loong64

 FFmpeg is the leading multimedia framework, able to decode, encode, transcode,
 mux, demux, stream, filter and play pretty much anything that humans and
 machines have created. It supports the most obscure ancient formats up to the
 cutting edge.
 .
 This library is a utility library to aid portable multimedia programming.
 It contains safe portable string functions, random number generators, data
 structures, additional mathematics functions, cryptography and multimedia
 related functionality (like enumerations for pixel and sample formats).
 It is not a library for code needed by both libavcodec and libavformat.
 The goal for this library is to be modular, small, efficient and useful.
 .
 This package contains the runtime files.
