Hi there,
When I play a video with VLC 1.1.0 pre2, and DXVA is enabled, which decoder is used? Is it the excellent decoder from ffmpeg VLC has, or some no-name decoder from ATI/NVIDIA nobody has tested in terms of quality?
Thanks,

So, the decoding is done by ffmpeg code, but it uses the GPU instead of the CPU?Decoder source code is from FFMPEG, but it uses DXVA API to do the decoding steps.
No, decoding is done by GPU manucturer, not ffmpeg.So, the decoding is done by ffmpeg code, but it uses the GPU instead of the CPU?Decoder source code is from FFMPEG, but it uses DXVA API to do the decoding steps.
I was under the impression that DXVA was a decoder embedded to the video card, and the player's decoder wasn't used at all.
This is exactly why I'm more excited about the possibility of multicore decoding than GPU decoding in VLC. I think it is more in VLC's tradition that the CPU (therefore the tried and true ffmpeg backend) does the work. I also think there are less variables to worry about in CPU-land.No, decoding is done by GPU manucturer, not ffmpeg.So, the decoding is done by ffmpeg code, but it uses the GPU instead of the CPU?Decoder source code is from FFMPEG, but it uses DXVA API to do the decoding steps.

Yes.Just to be sure ... we are taking about DXVA2, not DXVA, right?
DXVA is not supported, only DXVA2, correct?
You cannot. You can just hope.How can I be sure that the manufacturer's GPU decoder will be as good as the ffmpeg's decoder?
So I guess I should wait for 1.2 which will have multicore support. This will be the best, IMO, because the trusted ffmpeg decoder is used, while even a CoreDuo T2400 should be able to handle the load of 1080p h264.You cannot.
