How to use hardware accelerator through DirectShow

[sourabht]

Hi, I am trying to build a software decoder DirectShow filter which can use the video acceleration blocks like Motion Compensation or IDCT. I got no information other than a document from Intel which is not suffitient for uderstanding the complete implementation. Can any body help me in this and provide some information by which I will be able to use the acceleration blocks.

Thanks and Regards,
Sourabh

hello, Sourabh.

Today i discover Intel IPP library. I'm interesting in trying to make software with intel optimization. I'm going to have a look on this library. My idea if possible, will be to translate gplmpeg2decoder with intel optimization. But gplmpeg2decoder is already optimized for SSE2, so perhaps no need with this, but why not.

Have you tried this:

That's as complete as you'll get in terms of what the hardware can do and how to do it. I doubt Intel has a better internal document.
