Default Re: No XVMC with 8500 and 100.14.03 Beta

There's actually a lot of powerful dedicated video hardware on these cards - apparently the 85/600 models can offload 100% of HD-DVD and Blu-ray. Of course, it's possible that they've dropped mpeg2 support, but I'd be a bit surprised.

Now, how willing they are to expose this hardware - even in binary-only drivers in unclear - due to all the stupid security paranoid around the HD formats. So, that may be a source of problems.

The other problem is that XvMC is a dead end that cannot be effectively adapted to formats other than mpeg2. But perhaps there is hope for the future.

See here: http://lists.freedesktop.org/archive...ch/022893.html

If the usable acceleration architecture gets implemented, then we can have genuine hope that nvidia will hook their hardware up to it.

can you point to a page or thread that still lives? Last post was at march's end.

As DRM mostly is "security by obscurity", it needs a suitably obscure environment to work in. This means Windows Vista, period. Even Windows XP is too accessible for DRM to remain working, see the HD-DVD AACS debacle.

I think it is very, very unlikely that there will ever be HD playback support in Linux and other systems (all systems except Windows Vista).
And because the media industry is very powerful, they probably have enough influence on NVIDIA to make them phase out all video support features in due time. XvMC apparently was the first to go.

Maybe it's up to a nouveau like project to fill the gap with reverse engineering. It's a challenge but clearly not unsolvable.

What does the drm in hd disc formats have anything to do with hardware video decoding? Accelerating unprotected mpeg2/h264/vc-1 video decoding is what should/could be done, and that's all that Linux users need anyway since there won't be any hdcp support for Linux, ever, because it's not crippled with drm malware like Vista. Not that it matters since there won't be any (licensed) software hd-dvd/blu-ray players either, for the very same reason. Free software will eventually support playing them anyway.

Yes. Let's stick to the topic, which turned out to be Nvidia not planning XvMC for it's 8xxx cards' linux drivers...

XVMC was not removed from any GPUs (for Linux). The architecture of G8x GPUs is such that the driver's XVMC support does not work at all (as several have reported here) with G8x GPUs. XVMC support for G8x GPUs needs to be effectively written from scratch, and that task is currently prioritized behind other driver work (for Linux).

There is no direct relation, but there is the reality that media companies try to "enforce" rules like "there shall not be any high-resolution video playing without DRM".
Of course they want to protect their own property, but they don't seem to mind hurting others just as well.

I don't know about you others, but I'm perfectly capable of playing back mpeg2 1080 material. I'm much more interested into getting accelerated playback of x264 or get core avc for linux. MPEG2 is on the way to be replaced by x264 anyway.

Personally, if I had a 8xxx card I wouldn't mind that they skipped MPEG2 hardware acceleration for eg. x264 acceleration.

XvMC hw acceleration is very rare and one of strong selling points of Nvidia chips in Linux world. Via has XvMC acceleration but lacks 3D. ATI has good 3D but no XvMC at all. Nvidia wins because XvMC and great 3D are both supported in Geforce drivers. (Another great selling point of Nvidia products is fantastic tech support from Nvidia employees on this forum )

Ha Ha, Soon my Brothers and Sisters, soon.

First step:- Fix current driver issues.
Second step:- Add some more hardware support.
Third step:- Fix added hardware support.
Forth step:- Start working on XVMC, or create better HD support compared to what you get with Windows Vista (No DRM) (You never know...)

In your face M$
