Thread: Is AMD ever going to fix the critical video playback issue with Radeon HD2600 cards?

    First round of testing:

    This took quite a bit of time.I've tried the drivers with different kernels and with various window managers and DEs (KDE,Gnome,LXDE,Openbox,IceWM,JWM,...) and Compiz Fusion.

    9.11 runs fine.Everything works: OpenGL,3D,Compiz effects,but the 2D performance (resizing and moving windows) is extremely slow,using massive amounts of CPU time.
    Unaccelerated 'Shadow Buffer' is 100x faster for
    these operations.


    Xine
    ----
    With Xine/gXine, the video still suffers from the zoom + fat scanlines issue.The player outputs this message when started from the commandline:

    Code:
    lacing: 0
    lacing: 3
    lacing: 0
    lacing: 0
    lacing: 0
    lacing: 3
    lacing: 0

    lacing: 0
    lacing: 0
    lacing: 3
    lacing: 0
    .
    .
    .
    and so on


    MPlayer
    -------
    MPlayer plays the videos perfectly (without errors). Tried it with Xv video and OpenGL/2 output. Xv seems smoother when Compiz effects are enabled. With OpenGL output (single and multitextured),the video has occasional stuttering and uses a bit more CPU. XvMC output is not supported on ATI cards.


    Coming up: Playback tests with VLC and tests with older versions of the Catalyst driver.

    I'll do some SP2 tests later.

    VLC
    ----
    VLC crashed with most of the videos I tried to play (unsupported formats/containers?),but I finally found some mp4 and flv videos that would run.
    Xv works fine. Nice and smooth playback without glitches.


    Xine/gXine (cont'd)
    -------------------
    There's another problem with Xine: visualizations (like the scope and spectrum) are broken as well and tend to lock up the system/driver,forcing a hard reboot.
    Strange,cause everything works fine with legacy cards (such as the R200 Radeons) and fglrx.


    Older drivers
    -------------
    There's no difference with older drivers such as Catalyst 8.7

    Conclusion:
    -----------
    Xv (and OpenGL) video is broken with Xine/gXine,but works fine with other players.

    The other issue is windows-specific: Broken WMV video acceleration with VMR9 (renderless) on WinXP (SP3)

    I've managed to fix the bad video colors/corruption in WinXP by installing the latest Windows Media Player runtimes. But that's only half of the problem.

    The real issue is still there:
    No WMV video acceleration with the Video Mixing Renderer. It's really bad - VMR is more than 2x slower than the 'Legacy Renderer' (CPU load goes up to 100%).

    I remember reading that there was a Control Center option to enable WMV acceleration. Not sure if it is still there but can you look ?

    Older versions of the Windows Media Player are also apparently missing some flag required for WMV acceleration, not sure of the details though.

    Yes,the option is still there and it's enabled by default.

    Just tried the latest opensource 'radeon' driver with this card and Xv playback with Xine works like a charm.
    No garbled video / stripes, no tearing and much better 2D performance than the bug-ridden fglrx/Catalyst driver.

    Looks like video acceleration on Windows is broken even with the EVR renderer.

    There's even a warning on the Media Player Classic Home Cinema page:

    http://mpc-hc.sourceforge.net/

    Warning for ATI users : VC1 acceleration has been broken since the Catalyst 8.6 release. If you experience such a thing, please revert to the 8.5 build.
