no (maybe CPU performance again ???)


Wikimedia files do play for me in Firefox 3.6, although apparently
only (JS off) in the "raw" mode (small 320 x 240 1 MiB example):

I will.

No speakers connected. And from the testsuite, only 1

RATIO.OGV "pixel_aspect_ratio.ogx" 1'909'943 1.82 MiB
Theora+Vorbis | 28.28 s | 540 Kbps | ffmpeg2theora 0.10.2 | 352 x 288
16:9 25 fps
libTheora 3.2.0 2004-03-17 + libVorbis 1.0.1 2003-09-09

example has sound at all.

The IMHO better approach would be to get it working (in Firefox and Opera) down
to those 233 MHz, even if a 30 fps 1 min movie evolves into a 1.5 fps
20 min movie
then. The priority of the player should be reduced, and the sound suspended as
necessary if the video gets behind the sound. Also frame dropping should be
optional at most, otherwise the effect is "100% CPU used and 0% video visible
on the screen" (same trouble with VLC).
