    Just because Transmageddon / gstreamer has loaded your va-api driver doesn't mean its being used and in your case it won't be getting used because you have transcoded to ogg.

    To encode in a format that should use vaapi, choose AVI for the output format then it should choose h264 as the default codec.

    However, there is no point in trying unless you have the required gstreamer encoding plugins. What distro are you running and what output do you get when you run:

    Code:
    gst-inspect-1.0 | grep vaapi
    Also, make sure you are running at least Transmageddon 1.3. It seems your previous test used 1.2 and 1.3 fixed a bug that disabled vaapi.

    I use matroska + h264 and vaapi and omx works fine.
    How do you explain the difference in time and CPU load on screenshots?
    Special video for you, look carefully at what happens after 0.49s-0.50s


    Any questions?
