           Summary: html5 ogg video playback in firefox unusable
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: edwintorok at gmail.com
         QAContact: xorg-team at lists.x.org


Tried to playback some html5 video (using ogg fileformat), and its unusable: I
get maybe 1 FPS, or even lower, CPU is hogged 100%.
This is on a Intel(R) Core(TM)2 Quad  CPU   Q9550  @ 2.83GHz.

Oprofile shows:
 87534    72.0000  libpixman-1.so.0.16.4    libpixman-1.so.0.16.4   
fetch_pixel_x8r8g8b8

suokko on #radeon captured these fallback messages:
      Composite fallback: op Over,
      src 0x9578268:s fmt XRGB8888 (1280x678),
      mask None,
      dst 0x94c3538:s fmt XRGB8888 (801x423),


Test pages with html5 video showing bad performance:

HTML5 video pages with good performance:

With FGLRX I remember I was getting good performance on the dailymotion html5
testpage!

Sadly with the OSS radeon/r600 driver that is not the case, flash playback is
much faster than the html5 one :(

Xorg: X.Org X Server 1.7.5.902 (1.7.6 RC 2)

mesa - built from git master (but I don't think mesa version matters here, does
it?)
