> Did something like that happen with ffmpeg a few years back? A huge amount of the dev work was being done by one at-the-time abrasive guy. They booted him, he forked, the ffmpeg mainline went moribund while the fork line kept getting better. No, that’s not what happened with ffmpeg. Multiple developers forked ffmpeg in a somewhat abrasive way because they disagreed with the rest of the team. They wanted to focus on…
I mean it kinda depends on who you consider the abrasive guy. In my experience just like with linux a lot of the ffmpeg/mplayer folks were abrasive. Sometimes it bothers me sometimes is doesn't. Michael Niedermayer was the maintainer and a guy who did crazy amounts of work on ffmpeg. But he was also what seemed to be the BDFL. I'm not entirely sure what happened, but it seems like there was sort of a coup that took o…
Once again, no, it’s not what happened. A team forked but failed to gain significant traction and the original project is now the only one remaining.
The email you quote comes from just before the fork. Niedermayer was the main maintainer of ffmpeg and as stated there was disagreement between him and what became the libav developers about the possibility of adding new features while improving the code.
The libav team wanted to fully focus on code improvement and left in a very vocal and really obnoxious way. As anyone could have predicted history showed the they were wrong. It was completely possible to do both new features and code improvement at the same time.
Niedermayer resigned in 2015 because the way the fork was handled had made things painful for him which I fully respect.
