Apple TV Performance with CrystalHD

Maybe Davilla himself can comment on this.

Please don't do that unless you really know what you are doing Smile I can break that svn HEAD at any moment and I'd rather users not experiment with source code in an active development process. If you do, remember driver and lib are paired.

Forget what I said, on xbmc r28256 driver v r95 plays better than 1.0.3 but on the second video xbmc reverts back to software renderer.

Sorry, I don't track Linux PPAs, you should make a post in the Linux forum.

Hi,

Regarding ATV... Is there any possibility in the future to run XBMC with CrystalHD under OSX and get smooth 1080p 24fps or will we always have to use the linux option?

Unknown at the current time. There are still some things that can be done but I'll need some internal changes in xbmc to support them.

No changes?

Maybe you're talking about 720/60 support, but judging by your commits, looks to me like you've been going hell for leather lately Laugh

Either that or your dopleganger who doesn't sleep has been mucking with your code.

I know this is the Mac forum but there seems to be a mixture of OS's in this thread and I thought something that helped me might help others.

Yesterday I upgraded from XP to Win 7 on my HTPC which required starting from scratch.

Once I got all my media in and back to where I needed to be I played an MKV with Crystal HD as the default playback device and there was alot of dropped frames and a general feeling of the playback being slow, then fast, slow, then fast.

I played around with AV Sync and Sync to display etc and nothing helped.

What fixed it was in System > Video Output. By default "Use a full screen window instead of True full screen" was enabled. I turned that off so it was using true full screen and playback is perfect now.

Using latest SVN that doesn't start with a 3.

Thanks, that's good info for XBMC for Windows users running a CrystalHD.

FYI Scott - et al

I have just now hacked my second apple TV, after the first one has been doing well I thought I would do get another and ready for Dharma.
Thanks for all the help and suggestions Smile

Few Notes to help people who are using the guide
http://wiki.xbmc.org/index.php?title=HOW...he_AppleTV

1) I'm totally confused by "vi" as an editor - and since "nano" seems to be loaded by default - I use that instead

2) During the parted steps while repartitioning i kept getting error"
"Warning: The journal is not empty. Parted must replay the transactions before opening the file system. This will modify the file system."
I goggled and there were all sorts of hits and no good answers.

The commands shown are "parted -s" in which the "-s" is for scripted - meaning don’t ask any questions. If I removed the -s parted asked me if it was ok to fix the journal and completed the partition update.

3) In the guide you will see
Code:
[b]Create a .xsession[/b]:

echo "exec xbmc --standalone" > .xsession
# Logout
exit

[b]Reboot [/b]

sudo reboot

I think when they update the guide and added the "Running Firefox" step they accidently pushed down the following necessary block
Code:
Edit rc.local to restore launching xbmc at boot.

sudo vi /etc/rc.local

[b]add:[/b]

echo "exec xbmc --standalone" > /home/xbmc/.xsession

This needs to be done or the apple will not auto launch xbmc (prior to the reboot)


4) This is an open question to the guide regarding the apt-get install powersaved which in included in the prebuild image. It would be nice if the Apple TV was less of a hot plate but I’m unfamiliar with the lib and it seems to need a GUI to configure it. Any good ways to install and configure it manually and does it have any negative performance concerns?

5) Booting directly without the Stick - I'm going to post my notes and theory below since it's long.


Thanks to all who make this project possible and keep up the great work.


Regards,
Mike Pisano
