Re: Will the H.264 decoding have a linux driver?
There are other more recent threads about this, but there is still no news. That is correct.
There probably won't soon be any news either. Someone from NVIDIA said that there are no plans to improve the XvMC support in the Linux driver (which is where this could be added in), and someone else said that when we want an H.264 decoder, we should go and write it ourselves in GLSL.
