It's interesting to note the parallel, but there are a few differences between ecgs vs gcc and libav vs ffmpeg.
Perhaps the most important is that the ecgs fork announcement [1] was very diplomatically worded, intended to put an end to any bad feelings on either side, and recognized that FSF was completely in their right to be conservative when it came to developing gcc. Another difference is that ecgs really took off and eventually became the official gcc; libav doesn't look like it's doing the same.
