DirectShowSource with GRF and MPC Video Decoder SA Filter

[moviefan]

Hi guys,

I would like to take advantage of my graphics card that supports HA for AVC/VC1 material. Therefore I disabled all post-processing, installed the MPC Standalone filter package and created a simple graph consisting of the source file (m2ts) and the MPC Video decoder. If load the graph using DirectShowSource (in the avs-file) into VirtualDub for testing purposes, it takes some time until VDub responses with a massage "Timeout ... waiting for graph to start". Why does this happen? If I use DMO WMVideo Decoder, it works.

Regards,

P.S.: Not sure, if this is the right subforum, but I didn't quite know where it fits better.

Did you consider using MPCHC for playback - which supports DXVA video acceleration (if your content is compliant) ?

I intend to reencode using graph edit... I am using MPCHC for playback and then got the idea of using the SA filters to have hardware accelerated decoding for the reencoding process... How can I build a graph using the MPC SA filters?

You can't use hardware acceleration during re-encoding. The DXVA decoder can only be connected to a video renderer.

Partially correct: You can use DXVA using DGAVCDecNV. neuron2 plans on supporting VC-1 properly in time too.

Uh, that's CUDA, not DXVA - it's using the card's shaders, not the separate video decoder...

But it should be possible to write a custom renderer that just grabs the images from DXVA's decoding from video ram instead of displaying them - but that would need support beyond DirectShowSource...
