Hi! I bought my first mac last year, a late 2008 macbook 13'' alu, it's just fantastic.. I haven't upgraded to snow yet, and I have had absolutely no problem with flash, youtube, etc. in this year. Reading (partially) the thread I understand that the graphic card 9400M (which is inside my mac) is better than others and maybe that's the reason why I've had no problem with flash. My question concerns iMac. Are iMac going to have problems watching video on youtube and, since the entry 21.5'' has got a 9400M, is that one a better choice in this sense? I'm sorry, I'm a little confused :p
 
DXVA uses the Video Decoder of the GPU like:
- http://en.wikipedia.org/wiki/Unified_Video_Decoder (ATI)
"UVD currently only supports DXVA (DirectX Video Acceleration) API specification for the Microsoft Windows and Xbox 360 platforms to allow video decoding to be hardware accelerated"
- http://en.wikipedia.org/wiki/Nvidia_PureVideo (NVidia)

It should be more efficient (hardware decode in the gpu) instead of using the shaders, like OpenCL does.
Also you just use the API (DXVA -> Windows) instead to reinvent the wheel for every app.

Shaders are just one area you can choose to leverage OpenCL from on the GPU.
 
I can try on my G4 see if it runs the latest version properley on PowerPC.
Apparently MPlayer has controlls with this hack but not VLC. :S

Don't bother trying, there will be no PowerPC release.

Adobe has just apparently decided to leave FLASH forever broken just like Apple as done the same with Leopard on PowerPC. :(
 
German: no point in trying to convince coolbits with rational facts, he just will keep saying OpenCL is magic pixie dust that will solve all the shortcomings of Apple's poor graphics drivers.

Again, graphics chipsets from both ATI and NVidia have *dedicated* decoding hardware which is optimised specifically for this task. Apple has failed to support this for years, and even now can only support it on one card, supporting only a small part of their hardware!
 
I have a question.

Why does it seem that several people see their CPUs redline / fans spin out of control while playing HD youtube, while every new Mac I have access to doesn't exceed 75% CPU with even 1080P flash video??
 
Don't sweat it!

Honestly I wonder why I even post on this site. When did I EVER say that HTML5 could replace Flash tomorrow? Please quote me on this.

I've just about given up posting anywhere, this site included. It seems to me that there are a growing number of belligerent posters who are not only know it alls, but lack even a basic understanding of civility. One wonders how these folks get dates, keep friends and avoid from being fired from their jobs with the sort of puerile behavior they display on line. It reminds me of recess in fourth grade.

Cheers!
 
Just curious

I haven't had the problem with Hulu many are citing here, even on my 2007 iMac which has a whimpy nVidia 7600 graphics card. On my 2009 13 inch MacBook Pro and my 2009 Mac Mini, full screen, HD H264 video is as smooth as glass (the Flash pluggin grabs between 60 and 70% CPU cycles). Is this open CL at work using the nVidia 9400 M chipsets?
 
Processor and energy use is noticeably better with 10.1, but I have noticed multiple instances of Flash behaving unexpectedly with 10.1. Hopefully they'll fix the issues in the final version, and we won't have to wait for some 10.1.x.xxx.x update down the line.

So am I to assume h264 is the preferred video format that Flash uses on the internet? Or is it just a specific codec that they decided to add hardware acceleration to in this update?
 
this update seemed pretty good. but It doesn't work on any revision3 content (diggnation) so i downgraded.

Here we go again :rolleyes:. If you'd bothered to read the release notes it clearly states that Adobe are continuing to support PowerPC with the next version of Flash, but they haven’t in this specific beta release.

Everyone knows you resent Apple for the PowerPC > Intel transition (because you flooded the Snow Leopard discussions). That's fine. Letting that resentment run away with you to mislead others isn't. Next time check your facts.

True, but I've learnt a lot from German's posts (thanks German!). So rattle on coolbits :).

Ok lets go on :)
Do you think ATI or NVIDIA writes drivers for osx? They do for windows...
Do you think ATI or NVIDIA give all the detail on how to, to apple?
Do they give it to linux community? :)
No they just give a binary, closed source... :)

Ha, indeed! :)

coolbits: NVidia and ATI have made no secret voodoo pacts to hide their video decoding hardware from Apple AFAIK. NVidia and ATI appear to have a functional working relationship with Apple, for example the release of the 9400+9600 on the macbook pro. It doesn't take magic to get engineers to talk to each other. Apple has just never got round to supporting the hardware properly, and this detriments us OS X users. Apple makes a claim that, with only a limited amount of hardware to support, they can better tailor the software to their hardware. This is clearly untrue with graphics, where they lag substantially behind Windows machines; and this will sadly be a trend into the future by the looks of things...

Same with hybrid-SLI.

Same with OpenGL 3.x.
 
So if there are no secrets, where can i get full spec of ATI and NVIDIA chips to write a proper driver?
As far as i know NO ONE is able to make a proper driver but themselves and they do it only for windows so far.
ATI once said they will opensource for their driver, did they do it?

so true, so true... it is just a myth, that osx is optimised for the Mac (Hardware).
OS X also doesn't support Non-Uniform Memory Architecture (NUMA): http://en.wikipedia.org/wiki/Non-Uniform_Memory_Access
So the xServe and the Mac Pro (the systems with two cpus) can't use their full potential (till ~30 percent less performance compared to Linux/Windows on the same hardware).

Back to topic:
The lack of an API for video acceleration is nothing new:
"Mac OS X also includes MPEG-2 acceleration capabilities, but Apple has chosen not to expose that API for use outside their own DVD-Video player application."
http://en.wikipedia.org/wiki/X-Video_Motion_Compensation

I thought ATI's drivers were opensource for Linux?
