    Default Ati Radeon or Intel for HD on Linux?

    I would like known if is possible use hardware acceleration for full HD video 1080p using exclusively open driver.

    The Intel driver are open, the ati driver are half open, but i don't known if this functionality is present and if is good.

    Thanks.

    Note:
    In particular i like known if a graphics card (integrated on a motherboard) using these chipset could be sufficient.

    I see this old post:
    Radeon HD2600 for HD in Linux? and i would known if the situation is changed.

    I can partially reply on my question after i see:
    Feature Matrix for Free Radeon Drivers

    I hope to find some information about intel graphics chipset.

    Well there is h264 accelleration for intel i3/i5 (dual) chips in experimental state. I could not test it yet however. It is very unlikely that you will get this for radeon oss.

    The Intel graphics drivers work great for displaying 720p on my Macbook. No hardware acceleration as my chipset is a GMA 950.

    Radeon. The ATI cards are MUCH more powerful. For video, the OSS driver seems to work the best, but if you enable v-sync and set your video output to OpenGL, that works too. You really don't need hardware acceleration.

    intel-gfx X.org & liva lists + source code at:

    This can only do 1 HD + 1 SD stream simultaneously. More may work but not in realtime. This is true for other vendors too (AMD, NVIDIA). Though, I believe some NVIDIA chips can do 2 HD streams simultaneously in realtime.

    Thanks for the link.
    Best Integrated GPU for Linux
    Now the DRI2 is supported.
    Intel chipset could be considered the best solutions for the driver open source present on linux?
    Or Ati have better feautures (even on old chipset)?

    Note:
    Naturally i speak about open driver.

    What do you mean, "ATi is half-open"?

    At the moment, there is no HW decoding on Radeon hardware, but some will likely be written for the Gallium3d infrastructure. No idea when.

    For example regarding the 3d.
