skipping frames fix/issue. affected videos 1080ix29.97 abd 720px59.94, h.264 or mpeg2.

vertical sync blank causes skips/slight judder for me. xrandr shows my sony supports 59.94.

System ->Video->Playback:
VDPAU: On
Prefer VDPAU Mixer: ON
VAAPI: off
Adjust Refreshrate to match video: On
Sync Playback to Display: On
Sync Method: Video Clock (Drop/Dupe)

I have no tearing. compositing off.

vertical blank sync - none. 0 skips! no judder log;

vertical blank sync - let driver choose 46 skips. some slight judder log;

vertical blank sync - none = perfect playback of all videos so far. I presume this is not expected behavior.

my system a4-3400, gpu overclocked 800mhz, dual channel pc1600 8g tuned. xubuntu 64 desktop. hdmi stereo to set.

you don't have the right kernel pyrodex.

So that was the issue. Thanks for the double check!

Now with this setup I have a few concerns:

1) I've followed the XBMC startup steps and it doesn't startup properly. I have to login as XBMC user and then start it by hand. Any thoughts for a fix?
2) With the added mesa repo will this ever be merged into future ubuntu releases or will this repo be the future for this configuration? If it is the future who is going to maintain it for updates and so forth?
3) With the added XBMC repo will we be able to use mainline XBMC repo down the road or could I install XBMC nightly from xbmc.org just as well?
4) With the kernel will these customizations eventually be merged into ubuntu's release? The reason why I asked is I tried ubuntu's mainline kernel for 3.12.X and that was my issue.

Thanks in advance for the feedback.

Thanks again deadite66!

Any assistance on the auto-startup? Trying to make it wife friendly if she has to reboot the system.

[fritsch]

The setup shown in Post 1 implements an auto starting xbmc, that just restarts itself, if it crashes. No need to do anything manually.

Current nightly 11-16 fixed the scraping bug...

[pyrodex]

Ok so I've fixed startup and worked out that but have noticed one side effect when doing the startup. The HDMI interface isn't available after a reboot until I close XBMC once and restart it. I tried to put a 5 second delay startup in xbmc-standalone but no luck. Any thoughts on this by chance to resolve the issue?

[fritsch]

don't change the standalone script. Check startxbmc.sh or the upstart script, which already waits for udev-trigger.

Ok, I played several types of videos in xbmc today. h.264, mpeg2, xvid, 59.94p, 30fps, 29.97p, 29.97i, 23.97p.

I cannot get tearing to occur on the oss driver at all. And I have *vertical blank sync* - none. Playback is much better, only a few skips/judders, good av sync. I am happy with this.

Is *vertical blank sync* now obsolete/redundant on oss?

It took some digging to find a possible justified reason:

http://xorg.freedesktop.org/wiki/RadeonF.../#index2h2
anti-tearing flags- EnablePageFlip, SwapBuffers

in my xorg.0.log i have:
[ 24.996] (II) RADEON(0): KMS Pageflipping: enabled
[ 24.996] (II) RADEON(0): SwapBuffers wait for vsync: enabled

Prior to OSS, I had horrible tearing with this APU on fglrx. It was especially bad on youtube. Now with oss that is gone. Good riddens!

So isn't *vertical blank sync* - none, the correct choice for this mesa/oss driver?

[wsnipex]

let driver decide is probably best, did you try that too?

[fritsch]

None: Disables vsync
Always Enabled: Forces some special things
Let Driver Decide: Keeps whatever the driver has.

@pyrodex,

just curious, do you have the A6 Black Edition?

i noticed that you have not said anything about any artifacts on the XBMC GUI.

can you tell me what you get when you run:

Code:

lspci | grep VGA

just to satisfy my curiosity.

[gfisher]

@wsnipex. I tried- let driver decide, always and none. I was using always per the op and fglrx days.
@fritsch, thanks. Not sure why *none* fixes my minor skips for 59.94. But as always, I will keep digging for the answer. For now I will enjoy the awesome picture quality/temporal deinterlacing, skip/judder free playback. Luckily I have no tearing with it off.

I am running the A6-3500 unit.

Code:

xbmc@bedhtpc:~/.xbmc/addons$ lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] BeaverCreek [Radeon HD 6530D]
xbmc@bedhtpc:~/.xbmc/addons$

After working out my stupid install issues, which were my fault, I have played with it all night long and so far haven't had an issue with artifacts. I did do some tweaking in the settings and don't sync my display refresh with the video and so far no issues. Let me know if you need anything else.

EDIT:

Now that I think of it the ONLY issue I have noticed versus my Windows setup is that it seems slightly more darker than originally. I may have to tweak brightness/contrast to help but it was a quirk I noticed.

[locomot1f]

@pyrodex -- no, for some reason, i thought your A6 might have been running Richland -- something above Radeon HD 6xxxD.

fyi -- under Settings -> System -> Video Output
down at the bottom, there is the option to "Use limited colour range(16-235)
this might help your color issue.
