Hmmmm. There's probably just one guy who wrote the ffmpeg code for that format. _Maybe_ one or two more who contributed fixes or enhancements?
The ffmpeg project need to get in touch and get then to assign copyright to the ffmpeg project, then delete that format/decoder from ffmpeg. Then go back to Google with an offer to licence then a commercial version of ffmpeg with the fixed SANM ANIM v0 decoder, for the low low price of only 0.0001% of YouTube's revenue every year. That'd likely make them the best funded open source project ever, if they pulled it off.
