Build ffmpeg from master

[matteocontrini]

Hello, it is my understanding that this script currently takes the latest ffmpeg release source code.

However, since ffmpeg releases only contain cherry-picked commits and do not include all the fixes and features, there should be a way to instead build ffmpeg from master, which is by the way the official recommended way to use ffmpeg.

Could this be allowed with an option, perhaps?

Thanks!

The "master" branch of ffmpeg source don't always stay as "stable" as the "release" versions. They are "developer-known stable" so to speak.
And that's the reason of versioning them.

I personally don't build ffmpeg either from the "release" tarball or the master branch, but from the occasionally-updated "release head" from their git source. You can say they contain "user-known stable" changes.
The main advantage of this method is I get almost all the changes from the master branch while keeping the minor version intact.

I suggest to use the git release head snapshot, https://github.com/FFmpeg/FFmpeg/archive/refs/heads/release/4.4.tar.gz instead of the tagged release snapshot, https://www.ffmpeg.org/releases/ffmpeg-4.4.tar.gz for getting stable as-well-as latest changes.
