Default Re: Vdpau video scaling quality?

As far as I can remember I read this on some of the various PureVideo Testing pages. Anyway you will likely know better what can be done with the GPUs (c:
It sounded like it was an option within the video processor, so it wouldn't require the high-performance GPUs. Anyway maybe you can keep this in mind for upcoming GPUs which would allow better options there?

Another thing which is slightly offtopic, but which I am thinking about for some time now: Would it be possible to extend VDPAU by an interface that would make it possible to write post-processing plugins with CUDA which can be applied to the image directly in the video memory? - This would allow community-extensions for different deinterlacing, scaling, whatever...
Just a though... (c:

FYI, beta driver 190.32 has been released, which does include a higher quality scaling option, although it is only available on a few newer GPUs, with "VDPAU feature set C" (see the README for a list)

Any plans to add this to other GPUs in the future or is there a hardware limitation?

There are no immediate plans to expose new scaling options on other GPUs. Beyond the immediate term, I can't comment on future features.

so mobile versions of gt2xx card are "C" capable cards but desktop version are only "B1" - nice

I'm not so sure, I think at least some of the OEM cards sold as "G 210" and "GT 220" should also support "C" (but they are not listed at all in current Appendix A). Perhaps somebody could test this? German wikipedia claims they contain the new GPU's GT216 and GT218.
Note that the GPU's in the other GT2xx cards (240 - 295) correspond to the GTX 260M and GTX 280M that are also not "C" capable.

Does anyone actually understand NVIDIA's product naming? sheesh, my brain melts trying to figure out what card may or may not be compatible.

@Stephen:

Is there a difference in hq scaling quality between the new feature set c enabled cards ?

Will the new ION2 platform include this feature set ? With which opengl version ?

Thanks for the info !

Code:
GTX280		- GT200-A2	- VDPAU A
GTX260		- GT200-A2	- VDPAU A
GTX260-core216	- GT200-103A2	- VDPAU A
GTS250		- G92-420B1	- VDPAU A
GTX280M		- G92b		- VDPAU A
GTX260M		- G92b		- VDPAU A
GTS260M		- GT215		- VDPAU C
GTS250M		- GT215		- VDPAU C
GT240M		- GT216		- VDPAU C
GT230M		- GT216		- VDPAU C
G210M		- GT218		- VDPAU C
Then if notebook chipset will be folowed by desktop card G210, GT220, GT230 and GT240 then it could be intersting since "VDPAU C" chips not only have hardware MPEG4 part2 decoders but better HQ L1 scaling.

http://www.guru3d.com/news/nvidia-gt...-gpus-surface/

But I wonder what TDP GT240 will have - GT240M have 23W TDP

No. At present, all GPUs use the same default scaling algorithm, and, if supported, the same L1 scaling algorithm.

I can't comment on unannounced or unreleased products.

VDPAU Feature Set C GPUs would be the 40nm GPUs like the desktop GT 220 and G210 GPUs. Retail versions of GT 220 and G210 which you can buy off the shelf and internet retailers will be out soon it seems.

http://www.nvidia.com/object/product...gt_220_us.html

http://www.nvidia.com/object/product...e_g210_us.html

GT 220 and I assume G210 does support bitstream decoding for all 3 HD formats, H.264, VC-1 and MPEG2. It exposes ModeVC1_VLD and ModeMPEG2_VLD as can be seen in this screenshot I found on another forum.



I wonder if the features like the higher quality video scaling algorithm & MPEG-4 Part 2, DivX 4, and DivX 5 video decoding can be made to work in the Windows open source MPC-HC player.

DSC, Neither of those two GPU marketing names are marked as announced, and hence do not appear in the current 190.xx driver release. Everyone should be careful to solely consult the driver README regarding features that NVIDIA guarantees of certain GPUs.
