FFmpeg has been forked by some developers after their attempted takeover two months ago did not fully succeed. During these two months their repository was listed here as main FFmpeg repository. We corrected this now and list the actual main repository and theirs directly below. All improvements of their fork have been merged into the main repository already.
Sadly we lost a not so minor part of our infrastructure to the forking side. We are still in the process of recovering, but web, git and issue tracker are already replaced.
