I know that OpenVideo is AMD specific, however further research leads me to find that OpenMAX AL/IL/DL will provide hardware accelerated decoding which could then be fed straight into x264 rather than using Directshow - which is only as good as the weakest link, and by that I mean it cannot get hardware acceleration as the whole process cannot use DXVA.

So .. just thought I through this potential method out there and see what the developer and others think about this process.

I have already seen this - and tested it as well, its pretty quick (but I'd prefer a similar method using x264 for end result); http://bluesky23.yu-nagi.com/en/index.html#AsVideoConv
I have been working on hacking ffdshow to allow DXVA during video encoding for about one year. See this thread. Compared to developing on a new and AMD-only architecture, DXVA is much easier for me.

I am about to integrate this into Direct264, so be patient.
