XBMC for Linux on Apple TV (formally known as "iTV")

[mr.b]

In regards to a few posts I made in the super-long linux thread, I've compiled the linux port on the appletv and taken a look at the performance while idle. Originally I posted screenshots showing 50% CPU usage at idle but a portion of that CPU usage was attributed to my running an active x11vnc session. Without the x11vnc session running though, I still saw it running 30% CPU while idle. It's entirely possible that this could be related to me missing something or not having xorg configured correctly so I'm not trying to ring an alarm bell or anything.

Also, in case there are some low-level hardware experts on board here, I wanted to mention something that davilla from the awkwardtv forums noticed. The NVIDIA 7300 on the appletv is running pci express with only 2 lanes (2x) when running linux while the same hardware with the native OSX install runs full 16 lanes (16X). Can anyone point us to a possible resolution?

it's hard to say really how bad that is without comparisons from other platforms. Personally I'm really interested to see how this turns out because the appleTV as an xbmc platform seems ideal to me, it's got all the outputs I want, hopefully enough cpu grunt to do hdtv content (720p at least) and its silent to boot.

Hi

So it's does work in other mac ? like macmini ?

can you post your command for compiling please (fink, finkcommander etc ...)

thx in advance

Well it works on other intel based mac's. I can run it on my macbook
video is still slow since the video rendrer depends on pixelsahders wich the macbook and macmini lacks. there is a software rendrer wich is really slow since no heavy duty have been made to optimise it and i guess that alternate renderes are on the low priority list for now.

Here is an intersting article that I think is worth a read => Hacking the Apple TV

by far, the most informative thread regarding linux on apple tv can be found here:

davilla (Scott Davilla) has been a great resource in helping to get linux running smoothly on the apple tv.

Really hope that XBMC can be run on the Atv... dreading the thought of a PC back in the lounge to be honest... even in Cube or Small form with any sort of powerfull CPU/GFX its gonna be like a low fling aircraft...

Yeah, the Apple TV is an ideal hardware solution for running XBMC. I'd buy one for each of my TVs if it worked...

This project really excites me!

The latest official release of the 2.6.22 Linux kernel should probably solve that issue(?)

Geforce 7300 gt fb support

PS! Out of curiosity, which device drivers are you using (open source or the closed source ones from NVIDIA)? does Envy work?

I'm not 100% on whether 2.6.22 helps to resolve the pci express lane issue -- I believe one of the guys at the awkwardtv forums has been toying with it. I had to give my test atv back to its rightful owner and am waiting on a good deal to pounce on so I can get back to work on it. I was using the proprietary binary driver so I could take advantage of xvmc, where motion compensation for mpeg2 (ATSC tuner) is offloaded to the GPU. My current plan is a Freevo box with single ATSC tuner and the ability to timeshift. The tuner would just be for local broadcasts (the news, etc). Everything else I'd stream from usenet via newzbin NZBs, a NZB downloading script, and mplayer ala:

unrar p -inul <1st-rar-file-in-the-set.ar> | mplayer -noidx -

which allows one to play using rars as a source. The idea is to yank newzbin report info, store in DB, and create custom RSS channels based on whatever criteria I fancy, allowing the box to act as video on demand for most of the video content available on usenet (140 days retention at giganews). Currently, a freevo plugin seems to be the right way to do this, but that could all change as XBMC on linux matures.
