FFmpeg (Win32, GPL static variant, 7.1 release branch)

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. A static Windows (x86) FFmpeg build from Defisym based on the 7.1 release branch with all dependencies, even those that require full GPL instead of just LGPL.
