H.264 Support in upcoming nVidia driver

[gsellis]

Great news for 6200, 6600 and 7800 users.

nVidia driver 80 will accel H.264

Nice to see that PVP works when it works ("In Charleton Heston voice" arrgghhh darn you 6800 ) as planned. New codec, new code, presto! Sure makes these cards attractive for video and HTPC use! Who has the popcorn?

This is good news. Let me rephrase that. This is promising news, but seeing is believing.

Is the Inquirer running sub 2GHz machines? This is the 2nd article I've seen from them saying that HDTV h.264 playback is not possible with current CPUs.

Apple's implementation sucks on my dual Xeon, albeit "preview" software.

Sucks on my 2.5GHz Athlon 64 too.

The quicktime H.264 codec or whatever thats with QT7 runs fine on my system. I get the same FPS for both 480 and 720p.

I have the newest drivers from Nvidia, not the 80 beta or anything.

It runs fine.

So wtf are they saying when "we can't run it well on our setups"?

480 is DV. 720p is ok. 1080i is marginal and p (progressive) sucks.

I had a question about H264 performance last week, someone provided the following sample :
Serenity Trailer">http://images.apple.com/movies/us/hd_gallery/gl1800/serenity_1080p.zip</a>

That's a 1080p clip, so you can run that and see how it performs.

For what it's worth, I found videolan client's H264 playback to be considerably less CPU intensive than QT7s.

A question I'd have about H264 support in the nvidia drivers, is what player is actually going to take advantage of that ?

why does my amd64 3000+ setup with a 6800 GT struggle so much with h.264 and other HD clips?
I've tried multiple programs, and the best seems to be videolan player... but some clips like http://www.myhsr.com/storage/HD%20video/Bad%20Boys%202%20HD%201080i.mp4 is sooooo extremely choppy... but SiL from microsoft's site works 100% smooth with 70-80% cpu usage

I would think 1080i would be fine if 720p works. I'm pretty sure 720 progressive is more cpu intensive then 1080 interlaced.

1280*720 = 921600
1920*1080/2 = 1036800

Actually 1080i is more bits by a little. Not sure about TV standard, but HDV2 is 60 fps, so twice as much info, even if interlaced. That would be 2073600.
