Powermac G5 Quad online video performance

[blppt]

I'm not going to get involved in this anymore than I have but I'm telling you at least versions 11.1 and below DO NOT offer ANY video decode multithreading.

You are WRONG. Look, this is the last time I'm going to do this. I downgraded to Flash 9 just to further prove this. First pic is Flash 9, 2nd is 10.1.102.64.

If you people cant even see how obvious this is, I feel sorry for you.

HD Videos. Play. Smoothly. On. 10.1.102.64. They also routinely use more that 150% cpu time, especially at 1080p flash. Its called multithreading.

They DONT play smoothly and dont use more than 100% cpu on Flash 9. SINGLE-thread h.264 decoding engine.

My God, I can only provide you people with so many blatant examples. Its like arguing with a brick wall.

Here's a doozy, multithreading and SMP are not the same thing. If you argue that point, you'll only further the image of the making yourself look silly. However, Flash 10.1 is not able to do either. I'm not going to do research for you. I've tried and it doesn't work. Go read up on SMP and multithreading then apply it to Flash 10.1. It doesn't fit or work, as per Adobe, myself, and ifrit05.

You're taking this all too far. It cannot be done by any stretch of one's imagination.

And I just did it again. Check the last screenshots. Feel free to run it through any photoshop analyzer you want---it has not been edited. Nor have the others.

Did you ever think, that---just maybe---these mysterious whitepapers are talking about other elements of flash that werent multithreaded before 11.2???? The H.264 decoder quite obviously is.

And did you even read his post, the one you agreed with? He agreed with ME, not you, quite correctly, that YOU STILL NEED FAKESMC. I dont even think you understand what a DSDT is---you cannot boot a Hack with JUST a modded DSDT.

Regardless, the entire point was that you said something silly like "Apple does nothing to actively prevent OSX being loaded on generic hardware" which is clearly false.

You mean, sillier than somebody insisting that Apple doesnt do anything to prevent people installing OSX on their PCs? Yeah, I didnt think so. Or insisting a patched DSDT is the only thing you need to build a hack? Yeah, thats a doozy.

I just posted two more real-life screenshots proving you wrong. I honestly can't think of anything else to post to change your mind.

...I honestly can't think of anything else to post to change your mind.

Then don't post anything. I think this thread should die now. It's gotten out of hand.

The video decoder is a ActionScript. ActionScripts were purely monothreaded until 11.4. No exceptions. Nothing. This is an irrefutable fact of the design.

FakeSMC may be needed for slightly more incompatible hardware than others, I've only had to use it twice on older hardware. Currently, I do not use it or anything like it on hackintoshes I service. You may see it as a necessity, but with time your experience may be great enough to allow you to not need it. I never said Apple not allowing OS X to run on non-Apple hardware, only that there's nothing in OS X that actively prevents it. Passively, things exist, most of those can be patched through the kernel.

Now we've taken this thread rather beyond its intended scope. I ask, once again, that you please stop with this nonsense.

I don't have one, would think that a Quad G5, running XBMC, would be able to handle streaming 720p just fine. My piddling ibook G4 can 480p with no issues, I have seen a Powerbook 1.67 Ghz handle 720p from XBMC on youtube. 1080p might be possible, but....I'll let somone who has one actually comment on that. Here's that Powerbook G4:

This is all quite sad as a 35 dollar Raspberry PI can handle 1080p from XBMC.

XBMC and the NaviXtreme program add-on make Netflix irrelevant. The 1 Channel repository makes Cable TV irrelevant. XBMC rules all your internets.

EDIT:

ooh, a year old post...

I've been semi-successful in getting 1080p to work on the 1,67Ghz PowerBook G4. It requires XBMC 9.x and OSX Tiger.

The reason raspberry can do 1080p is because of the graphic acceleration. PPC can only use altivec acceleration and it can't compete with a GPU in most cases. (there might be some extremely well-written altivec optimization out there for other types of applications but not for ppc).

Here is an example of XBMC 11 under OSX 10.5.8 (not the fastest performance but still you get an idea:

Listen, I dont know what your problem is, but you are wrong. There is no explanation for me being able to play 1080p youtube videos smoothly on a G5 quad other than h.264 flash being multithreaded.

altivec?
