MPEG2 Video Decoder Filter with DXVA Support

gowthamhk · 31st July 2009, 13:37

Hi,

I am writing MPEG-2 filter with DXVA support.

I have called BeginFrame() with surface Index, Execute() with necessary buffers and EndFrame() with the same surface Index. All these functions returned status S_OK. Still when I called DisplayFrame() with the same surface index and IMediaSample pointer, I am not getting any output.

Now, the question is, before calling DisplayFrame(), do I need to call any function to know the status of actual decoding operation or the return status itself indicates that the decoding operation has been done successfully.

Please reply if anybody is aware of this,

Cheers,
Gowtham

we've been toying with the idea of adding MPEG2 DXVA too MPC-HC.

Casimir says documentation is lacking though, he might be able to answer your question. Or even better, maybe you could work together? (assuming your solution is open-source and GPL compatible)

OK, I should wait when he ll ans to my question then.

I can definitely support and contribute for MPEG2 DXVA support for MPC-HC, but not with whatever I am writing right now. (since it is not open source and GPL compatible)

Cheers,
Gowtham
