Any opensource MPEG-2 decoder with DXVA

[gowthamhk]

Hi,

I did some search to come up for nothing on any open source MPEG-2 decoder with DXVA support as well. I was wondering MPC supports DXVA for H264 but not for MPEG2.

If anybody knows any open source MPEG-2 decoder with DXVA support, Please reply.

Thanks

Mpeg2 is so relatively easy to decode in software that no-one has done this yet.
only a small sampling of videocards actually have hardware mpeg2 decoding.(most of it is assisted decoding which no open source application supports)

the Microsoft decoder that comes with Vista and Windows 7 uses DXVA. but hardware acceleration is a bit useless for MPEG2...

Hi tetsuo55 and Mangix, Thanks for your info

Even though its a relatively simple decoder, I wanted to use it to take off the load from CPU as much as possible. For that I thought of referring one if available.

Hi,

DXVA1.0 spec talks about Slice Control Buffers for off-host VLD processing. But I use nVidia Quadro FX 540 which does not support MPEG2_VLD (as from DXVA checker).

That means, I can't pass Slice Control Buffers to process VLD on my machine right?

Anybody has idea regarding which card supports MPEG2_VLD mode?
