The VAAPI for GPU accelered video decoding on Linux is really interesting. I don't know enough about video to understand how low-level it is from the MPEG2 exemple on their web site: does it have to be a codec already supported by your video card as I understand, or can you code new ones with existing building blocks?
- ars 16y agoIt needs to be a codec supported by the video card. See http://en.wikipedia.org/wiki/Nvidia_PureVideo#Table_of_PureVideo_.28HD.29_GPUs http://en.wikipedia.org/wiki/Nvidia_PureVideo#Table_of_PureV... for a list of Nvidia GPUs and which codecs they support.
- plesn 16y agoOh, so that's a disadvantage for VP8 against h264 on current cards. I wonder how well such a decoding can perform implemented on OpenCL/CUDA vs the pure "supported" version..
