[GMA X4500] GPU video decoding (VA-API?)
I have a laptop with this card (Samsung X360) and I'dd like to play 1080p x264 videos, is there any way to have enhanced video playback like through VA-API/VDPAU? I can pull latest git drivers if needed, I can also enable gallium3d if it works.
Does this GPU support 2560x1600 and 1920xYYYY (1080p) resolutions through HDMI? Under windows I have never been able to set a 1080p resolution.
Not this year, when you run
On a new Debian/Ubuntu distribution with libdrm 2.4 or newer then you can use vainfo and mplayer -va vaapi -vo vaapi. But ONLY for MPEG2 currently. Next year this might change - the script will be the same.
Why even develop VA-API any farther. I wish everyone would focus on Gallium3D.
Your comment shows you don't know what either of these terms mean.

The xvba-video wrapper fails because of ATI's inability to decode certain h264 videos and it does not work for MPEG1/2 with xvba.
Can Gallium3D not contain a video decoding state tracker? Now I have to take back not using VA-API, as I got it confused with VDPAU. VA-API can already use VDPAU as a backend, but why not restructure it to use a Gallium3D state tracker instead?

[No GMAX4500 inside! My motherboard sports a G33, e.g. the previous generation]
I upgraded all the xorg/mesa/intel/vlc files yesterday, and also libc6 (2.10.2-5), and after a couple of tests with a few FullHD videos I have been testing for a year, I witnessed a huge improvement: perfect fluidity (which was reached thanks to a previous upgrade of all these files a couple of months ago), and a surprising very low CPU usage (Core2Duo at 2.8 gHz).
I am happily astonished!
xorg and xserver-xorg: 7.5+3
libdrm2 and libdrmintel1: 2.4.17+git20100120 (got it thanks to Ubuntu sarvatt karmic)
I updated several packages, and CPU usage has increased enormously.
A very unfortunate regression.
Packages involed in this regression: the mesa 7.8.0-git20100210ubuntu-sarvatt-karmic related ones I guess.
If that really is a Mesa regression, now would be an excellent time to bisect it, with 7.8 soon to be released.
Any updates folks? How are things running these days for the GMA 4500MHD?
I am drooling for the Dell Vostro V13 with Ubuntu preinstalled. I don't need extremely demanding 3D Gaming but I'd really like it to play things like Flash video at 740p (1080p). I've been reading reviews, benchmarks and what not. I also own a much lower spec'ed Vostro A90, and from my experience the real issue is freakin' flash. Everything else is a pleasure.
Anyways, any thoughts, updates and or or pointers would be greatly appreciated.
