When enabling the youtube html5 video player on a openSUSE PowerPC
Firefox 4.0b10 build, the video is distorted. It plays, sounds is fine, just the displayed video is incorrect.
Steps to Reproduce:
1. enable html5 video on youtube
2. play a youtube video
video looks badly displayed
video displays correctly.

This doesn't seem to be a problem with Firefox 4 final (thouh I'm on intel, not ppc).
Is Firefox 4 final available from wherever you got your b10 build from?
i updated to firefox 4.0 today, same effect still.
any idea how to debug this?
Karl, Matthew, any ideas? I wonder whether this is a PPC issue in the webm code...
Marcus, do you see similar problems if you play an Ogg Theora video instead? That'll help narrow down where the bug is. I suspect it's in the gfx/ycbcr code, which is shared between all of the video decoders, so if I'm right I'd expect Theora playback to exhibit the same bug.

Out of band discussion suggested this might be bug 640588, which is fixed in the trunk nightly builds. Can you please test a nightly and report the results?
xine u6sdgeu4t8gq.ogg is ok and shows the testvideo.
firefox u6sdgeu4t8gq.ogg shows the video distorted like above.
I will see if I can get a nightly build up, the bug 640588 looks like the same distortion, although I am running a 32bit visual
(bitmap unit, bit order, padding: 32, MSBFirst, 32)
Have you had a chance to test a nightly build?
I tried Wolfgangs provided 5.0a-20110427
but it does not build on powerpc 32bit anymore.
--disable-ipc no longer seems to work, and I run into ppc related errors during build.
any specific magic to build for Power?
--disable-ipc was removed in bug 639754 :-(
I'm looking into finishing bug 587188
i tested wolfgangs build now, and youtube html5 videos render fine.
So this is fixed I think.
Great, thanks for confirming.
