XBMC for Mac OS X on PowerPC (PPC) CPU systems ? - SandmanCL - 2008-02-06 07:49
Since all the porting effort has been for Leopard and Intel I know that right now I'd be out of luck getting XBMC to build on my aging Powerbook G4.
However, are there any logistical reasons XBMC wouldn't compile on non-intel macs ? The GPU in the Powerbook G4 does OpenGL 2.1 and the CPU should (?) be fast enough to decode relatively high x264 resolutions.

A lot of code is x86-dependent. Especially the DLL Loader. We're still having trouble getting 64-bit working.
If someone is willing to submit patches, go for it. Otherwise, I wouldn't hold my breath.

XBMC has been compiled partially successfully (not feature complete but runnable) on the a 64-bit PPC system (not a Mac). However, we never received a patch for it and this was a while back. So, it's not impossible, just not something any of the current devs have a motivation twoards doing.

Everything has its place for development. Even XBMC. The Bigger problem lies in how to get the programing stable and usable. Power support is just allot of work for what is going to be a legacy platform. Great for the home user and office and server duties but just not where it is at for future development. ANYTHING IS possible. Hell I'm upgrading my xbox cpu to 1ghz and upgrading the ram by sending my board to Shen Zen China. With enough money, anything is possible. Well almost. Vista will never fit on a CDROM. But other then that, you get the idea.

Always google before you type
In other news imickey just volunteered to port XBMC to Motorola 6800 so my grandma can enjoy XBMC!

Porting XBMC for Mac OS X to PowerPC (PPC) could be a perfect Google Summer of Code (GSoC) , if you could just find a programming student who is interested in doing this project.
Quote:* Fully port XBMC for Mac OS X to compile and run on PowerPC (PPC) architecture

So when you think about it, porting XBMC for PowerPC (PPC) for Mac OS X would be the first step in getting XBMC to someday run on the PS3 or Xbox360, but that is an off-topic discussion for this Mac OS X forum.

Holy $%&^% No way! feels like finals when that test bit me in the Arse! BTW, I will bake your grandma cookies. Clean her house. And mow the lawn. BUT THERE IS NOT ENOUGH MONEY IN THE WORLD TO GET ME TO WRITE ONE APPLE SCRIPT OF CODE FOR OS9! HELL EVEN OSX . I can't even get Jaguar to work correctly with updates on a beige G3. I always seem to find every dam Bug in the world with the old powerPC platform. From networking issues to just getting a mac to share drives with XBMC via samba.
Programing for Power is like going to the dentist. You know you should, But you just don't wana.

As a XBMC/XBOX user for several years and an excited observer of OSXBMC and an owner of Intel and PPC macs I must admit I see no benefit to XBMC being ported to the PPC's ?
Personally, I was wondering what the heck I was going to do when the eventual move to a Hi-Def tv happened in my house with regard to XBMC.
XBMC on the Xbox is unbeatable for standard def tv watching. PPC would be unable to handle 1080i ( not sure about 720P) so what's the point there ?
Why would you want to replace an Xbox XBMC with a Mac XBMC that can't do any more ?
I'm looking forward to the mac Mini-in-a-time-capsule-enclosure that should be coming soon apparantly.....and I'd imagine it'll use the remote Blu-Ray feature which will soon follow RemoteDVD.
OSXBMC on Intel Minis is the future of High Definition Home Theatre.

petejo Wrote:PPC would be unable to handle 1080i ( not sure about 720P) so what's the point there ?The fact is that 1080i resolution videos takes more CPU processing-power to decode than 720p resolution videos, and on-top of that you need a relative modern GPU to deinterlace 1080i otherwise you have to run the deinterlace filter in software on the CPU which makes 1080i even more CPU hungry.
...and as for the point(s) to port XBMC for Mac OS X to the PPC-architecture, I see at least three:
1. It would be a challenge, and many skilled programmers like a challenge.
2. Many people might already own a PPC Mac and can't afford to upgrade.
- Also, those people same might not even need high-definition output but would be satisfied with standard-definition output.
3. Like I already mentioned, porting XBMC for Mac OS X to the PPC-architecture could be seen as the first step for XBMC on the PS3 and/or Xbox360.
So just because YOU do not see the point does not mean that others won't, thus IMHO you are better of keeping quiet.

the truth is that porting xbmc to intel procesors and better yet to 3 different OSes, is at least great, xbmc was getting lost because xbox1 are starting to fade away either because they have stopped working or because simply they are big, no wifi and hdlimited. Thanks elan for your hard work i still cant believe Im using xbmc again
- petejo - 2008-03-29 07:15
Oh, so because I dare to express my opinion, which doesn't agree with yours, I had better keep quiet ?!?
Right-o mien Fuhrer !
Free speech buddy.......

i dont thing so try play HD x264 or H264 in vlc player and you will see G4 dont have power to decode
- imickey503 - 2008-03-29 13:59
here is a quote from a pro
Your processor is the culprit. HD video, particulary H.264 encoded video, requires a huge amount of processing power just to play.
I had the last G4 Powerbook made (1.67gHz, 2GB DDR2 matched pair, ATI 256MB video) and could barely do 720p at native size without skipping and other issues. Same issue on a MDD with dual 1.42gHz G4s. The MBPro I have now has no issues at all.
Might be a good time to consider an upgrade if you're going to be messing with a lot of HD content. The new iMacs (and the Minis for that matter) will handle it with no problems. G4s like yours are still fetching around $650 to $800 on eBay last I saw.
Apple's official recommendation for 720p HD in Quicktime 7 is:
720p on an iBook - Plantain - 2008-05-03 02:01
FWIW, I can playback 720p x264 on my iBook G4.
Compiling all the necessary stuff yourself with Alti-vec addons _really_ makes a difference (Gentoo Linux)
No hope under OS X though, I get about 6fps with VLC.
Anywho, the moral of the story is - PPC isn't dead!
If we're ever going to see XBMC on the Xbox 360 (Or better yet, the PS3), we need a PowerPC port.
I gave it a go once, only to find significant portions of the codebase have been converted to assembly needlessly? I found myself spending hours trying to figure out a piece of assembly was doing (was usually something silly like printf :/)

I know a lot of people don't want to upgrade computers. Or simply can't. But keep in mind Apple isn't going to support PPC machines too much longer, and many other software vendors aren't at all. Not to mention as new Intel machines are released the cost to switch over to an older Intel machine from a PPC gets cheaper and cheaper.
That said it was stated that porting to PPC would be a jumping point to getting XBMC on a PS3 or similar PPC machine. Now that would rock. Cheaper and more powerful() then a Mini and with Blueray DVD support. Ahhh to dream. But I digress as I've slipped into off topic as well.
