  • VAAPI or VDPAU?

    Using the open source radeon driver- which of the above video acceleration is the best to use?

    TIA,
    Caveman.

    Whatever you or your app need i would say, just like choices for encoding OMX or VAAPI.

      So if the app supports both apis there is no lib which is better supported by the driver?

        Support for either is equal in the driver, but there can be differences in the application. For example, VLC supports zero-copy VDPAU, but only copy-back VAAPI. Copy-back is more resource intensive, as decoded frames are copied back into system RAM. With zero-copy, the frames are displayed directly.

        So if VLC is your player of choice, go with VDPAU. But if you use mpv, the API doesn't matter, mpv has zero-copy with both.
