Firefox HTML 5 Ogg Theora playback

Apparently, playing 320x200 15 FPS native HTML5 (Ogg Theora) video in Firefox on FreeBSD takes less than 1% of a CPU core, and that's with X11 compositing enabled (translucent window), but not AIGLX. Nice. However, the "same" video at 640x480 at 30 FPS takes around 10%. It looks like audio is unsynced with video in both cases.

Surprisingly, even though the video drivers are presumably vastly better on Windows XP, playing the bigger video takes almost 80% CPU cycles of a CPU core. I have no idea why.

Unlike with your blog comments, Opera actually plays that video without issues.

Opera sucks big time. Among other things, Opera 10 doesn't play Ogg video by default.

I do see noticable more cpu usage on Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.5pre) Gecko/20091013 Shiretoko/3.5.5pre, but not enough to discourage me from writing a web font-end for it: http://github.com/dpavlin/HTML5TV


I'm betting that support will be better with time, basically...
