fritsch, more than an hour of LiveTV interlaced content playback with SS enabled and so far so good.

Yeah! This sounds really good. Packages will hit xbmc-xvba repository when launchpad ist ready - build pending.

[quote=kobik]@Infinitatus,
Set VSync to always on under System->Video settings.
It's the FPS that is going crazy here, but putting a limit on them will decrease your CPU usage on idle.

How dum of me. I see it now. Thanks (already down to 10%)

Installing using Oneiric Minimal is not an option for me. My Wifi card is not detected by it (I only have a Wifi card in this device!)

I've since downloaded the full 11.10 Ubuntu CD with the hope of installing a minimal CLI version of Ubuntu from that which does include the driver - but no dice - I couldnt work out or google the correct answer.

Can anyone assist getting a Minimal install on my system so I can attempt to do this please?!

Just use the normal desktop version, if you start xbmc as a lightdm session as instructed in the guide, there won't be too much overhead. you can still slim down later on if you deem necessary.

No crashes at all on playing interlaced content this evening.
great work guys!

On system reboot XBMC crash in a loop for 6-8 times in row Sad
Happened for me a few times already also with the stable version.

Did you install everything like provided by this howto?

Normally system reboot crashes are not xvba dependend, but the xbmc.log could tell more.


- kobik - 2011-12-18 10:37

Of course.
Not to be offensive of course, but these and other menu navigation crashes didn't not happen using Lars' git.


- fritsch - 2011-12-18 10:51

Mmh, we are totally based on Lars git. We rebase on him.
Could you provide xbmc.log files? When this crash happens?

Again: Crash means: your xbmc session just "restarts"?


- kobik - 2011-12-18 10:55

By crash I mean that XBMC process is destroyed.

I'll provide the logs later this evening when I'll get home.


- kobik - 2011-12-18 11:12

I would recommend to add to the OP to set VSync to always on under System->Video settings, so the CPU usage on idle wouldn't be so high.

Edit: What extra packages or settings are required for suspend/resume besides what stated in the OP?

Did you try to follow the logs?
On mine, my DVB card and network wasn't detected with 11.10, so I needed to download a firmware and deb files and install them manually.


Different frame rates - garbled screen - grad - 2011-12-18 14:24

Hello,

first off, huge thanks for this effort. It made me - finally - seriously consider dumping the MythTV frontend.

However, there's one BIG showstopper: in MythTV, I used to have the player automatically switch the screen to the proper refresh rate, most notably 24p. While XBMC seems to support this, and even actually and properly xrandr's to the correct mode, the display is totally garbled. It's ok when I escape out of fullscreen mode back into the menu. xrandr works just fine on the console, and of course in the MythTV frontend.

Everything else seems to work just fine, including advanced shaders, XvBA, and shared surfaces. When I turn off all XvBA options, the problem persists.

My system: RS 780G Radeon HD 3200 on Mythbuntu 10.04 Natty. Compositing turned off in xfwm4. Catalyst 11.12. Using the xbmc-xvba ppa. I did turn on debugging and analysed the log, no apparent errors. Anything else needed to pinpoint the cause?

Thanks for any help and pointers!

This works fine with us. Could you give the output of xrandr -q?
Does it work, if you switch the mode in xfwm before and just leave it untouched in xbmc?
