  • media center with HD 2400?

    I'm running an old laptop as a server, and it works great. Recently I was hoping it could double as a media center, and installed xbmc on it. It works great, but the performance on 720p is not usable.

    I've only tried the fglrx driver so far, and I couldn't get mplayer's xvmc working. Is there any way I can get hardware acceleration with the gpu from either fglrx or the open source driver?

    OK, IANAMCS (Media Center Specialist) but here goes.

    A few ideas/questions:
    -Are you sure that the graphics card is the problem? (could it be a cpu bottleneck?)
    -Does xbmc use the graphics card a lot? (openGL > Xv > raster) if not, see point number one.
    -What are you trying to play (H264 is expensive to decode, and on linux only the NVidia Blob currently has support for gpu assisted decoding).
    -What chip do you have in that card (r300: you could try the open drivers since they're faster than Catalyst under some workloads).

      - It's defenatly a cpu bottleneck, hence the need to offload to gpu.
      - Valid point, I might be able to reduce some load there. I'll check this out.
      - There was some work with galium3d to do gpu assisted decode atleast, this is basically what I'm looking for. But I have no idea in what state it is currently.
      - I think it's a R600 chip.
