Perian is shutting down
This is a shame. I absolutely love Perian and it has made it much easier to just play content without having to download VLC as well, and it just worked.One thing I have noticed is that support for MKV/VP8/WebM has always been pretty bad. It uses a LOT of CPU time and in general was really slow. When YouTube put me in the HTML 5 beta it was unbeknownst to me sending me WebM content because I had Perian installed and it was causing HUGE spikes in CPU usage and overall lag because it was trying to decode and render WebM, whereas h264 requires almost no CPU power on my older MBP.I hope that the community as a whole picks up the project and helps it succeed, it would be fantastic to still have it around.
