IPv6 doesn't fix most of the problems with IP, in fact it makes some worse (routing tables are now bigger because of bigger addresses and there can be more of them). If IPv6 actually did attempt to fix issues in IP it might have seen faster adoption.
You can't view it on youtube either from Norway, the UK, and many other countries. "This video contains content from Channel 4 s/f, who has blocked it on copyright grounds."
While Libav left with the server, bug tracker, etc., the FFmpeg project was restoring itself, with the help of some VideoLAN people (the FFmpeg sources are now hosted on git.videolan.org). Michael also started to merge the Libav changes back into FFmpeg every 1-2 day, with a lot of forgotten, previously rejected, sometimes controversial features, or in stand-by such as ffmpeg-mt.
The main point here is that the fork stimulated the competition, and FFmpeg became a way better (IMHO) and more complete project. Also, I must say the leader's attitude completely changed, in a very good way. This is certainly one of the most positive thing that came out of that war.
