Re: x264 and Intel 4500MHD said by Matt:The G45 was released in mid-2008. So if Intel was asked to provide the spec in September and there was something working in March, I'd say that's pretty damn good. Especially since nVidia won't open source their drivers at all. The page you linked to details that an Intel engineer himself fixed the problem. No if you read them carefully. 1st post is MPCHC open source people asking for technical details to get the hardware to work in Sep 2008. Also again Nvidia and ATI disclosure has been more open that why open source has gotten h264 to work correctly.
"So my question is : does Intel use a specific protocol for bitstream decoder, and if so is it possible to have the specifications?"
Feb 2009 is when a Intel person finally responded to that request, and March 2009 is when Eric of Intel with the help of the open source MPCHC people got it working. NOTICE: It was Eric of intel doing all the work, while the open source people just provided technical help in regards to open source MPCHC, and not the other way around, again to what I suspect to keep Intel "trade" secrets.
So September, Oct, Nov, Dec 2008, January, February 2009. Several months of idle in 2008, 2009, finally a response in 2009? Not exactly responsive, the same MPCHC people coded ATI and Nvidia h264 hardware stuff for their open source player months ahead of time. If open source people can do Ati and Nvidia that fast and they aren't paid, then why can't Intel be more responsive. In fact if for Eric's generosity and whim, there would be no non commercial 264 acceleration.
Also the fact, that intel person said XP wouldn't be supported, limits the options of people who has issues with Vista. I don't know the technical details, but my daughter XP machine with the nvidia integrated runs h264 acceleration fine and that chip was released earlier than the 4500 mhd so I don't think it a technical. I suspect HDCP rules again.....Intel and Microsoft with HDCP can be scary. And yes, there were people like me trying to get h264 to work right without luck in 2008 and even now because the 4500 mhd h264 is far from perfect.
I have not installed windows 7 RC on the labtop b/c I don't like the hassle of switching or dual booting a computer. But if windows 7 runs h264 acceleration well for the 4500 mhd like some people posting on forums say, then Intel has a real double standard on how they treat their commercial (Microsoft, cyberlink) and open source counterparts in regards technical disclosure. I don't know why you are defending Intel or doubting what I am saying because they you sticking it to you and me. So yes I am frustrated with intel. |
