Perian was fine(though far from perfect), and open source has a time and a place. But in my opinion Perian showed how bad it can be. Slow updates, abandonment, lack of competition, of the top of my head. I think a commercial solution to mkv/avi/flv/etc support in Mavericks would have the potential to be much better, more constantly updated, and more supported if large rewrites were needed(albeit with another purchase required probably). Anyone agree? clearly there's not enough interest to get perian development going again, just look at the google group for it. Anyone have any ideas about which dev in particular this project would be suited for? I was thinking Yazsoft maybe. Could we set up a kickstarter or something?
