Static Windows Builds of ffmpeg master and latest release branch.
EXPERIMENTAL Linux-Builds. Do not expect everything to work on them, specially anything that involved loading dynamic libs at runtime.
Shared Linux builds come without the programs (hopefully just for now), since they won't run without musl.

Shared Linux builds need musl installed to run the programs. YMMV when trying to use the libraries.
Please report any issues you encounter with those builds!
