Thanks. I'll be looking into those examples ASAP.
// FIXME use direct rendering
I need to know how to fix that FIXME.
This is not related to va-api at all.
I selected that //FIXME because it specified "direct rendering", which I
took to mean "handled by the GPU". It seems I was mistaken there.
My conceptual understanding of va-api thus far, within the ffmpeg
framework, is that libavcodec will read an encoded video frame, then use
va-api and the GPU to perform decoding of that frame instead of
performing decoding in software.
The end result will probably be a frame in YUV. I'll need to run the YUV
to RGB conversion on each frame if I'm running OpenGL and this will
still be CPU intensive. I would benefit from the hardware frame decoding
though, and that alone should make a significant difference.
Is this correct?
