[SECURITY] Fedora 39 Update: ffmpeg-6.1.1-4.fc39

FFmpeg is a 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. No matter if they were designed by some standards committee, the community or a corporation. This build of ffmpeg is limited in the number of codecs supported.
