define 'a little' ;-)

due to recent revert (why the heck?) i did not try out motd2k's patches and so for me everything is 'a little very' jerky.

Hummm hard to define, everything can be smooth even at high bitrate, but sometime even at low bitrate i can have a small slow down for 1:10 of seconds, a sort of lag, though no frames drop!!

seems rather like a refresh mismatch between your tv and the gpu. what refresh rate are you using? does it match your movie? vsync on? does it occur frequently?


- sensei73 - 2009-03-19 11:34

I activated auto select refresh, the movie is 23,976fps, the tv vsync is 24Hz and but I had to tweek a little bit my xorg.conf otherwise I get some problems with audio/video syncronisation
"ModeLine "1920x1080@24" 74.285 ..." instead of "ModeLine "1920x1080@24" 74.260"

But again, I do not have this problems with software decoding with the same settings.

Well that changeset is still on SVN - you'd just have to check out the revision before the revert... ie 18670.

Don't think that this isn't high priority though.

Yeah i understand - and i do know how to get the old revision (working with svn all day long), but i wanted to know why your patches got rejected by elupus (as svn log states).

i cannot stress this too much: thanks again for all your time, effort and patience.

So... I'm going to US in a few days and I think I'll get a new mini to become my media center.. I know I could spend less money with a more power intensive solution, but I want something small with low power consumption.

My question: anyone here ever tried VDPAU branch running linux on a new mini? I've tried to find benchmark results here with no success Smile Wondering if the VG is good enough for that, maybe with 2GB that gets 256mb allocated for the GPU ram....

I was wondering about the revert too. Does that break compatibility with 8xxx IGP sytems again?


- Haggy - 2009-03-19 17:42

Did it fix'em? I did not build since 18652 due to the revert.

Has this fix been commited to the VDPAU branch yet?

I just compiled 1h ago and it didn't solve my problem...


- adrian - 2009-03-19 19:08

18670 fixed the problem with SD shows only playing audio, and seems really solid. I wasn't having the stuttering problem others were complaining of so not sure about that.

VDPAU is at linuxport 18629 - if it was commited to linuxport after that it's not in this branch.

Why not check for yourself?
Code:
svn log http://xbmc.svn.sourceforge.net/svnroot/xbmc/branches/xbmc-vdpau/XBMC/xbmc/GUIWindowVideoBase.cpp

is not that complicated!?

EDIT: If you are willing to fix possible merge conflicts for yourself you may patch in the fix for yourself. see http://svnbook.red-bean.com/

Waaaaaaay over my head Wink
...let's put it this way: I have to Google (and will do) most everything I do on Linux and I am on my first week of XBMC Wink

OK Smile Then...just wait. motd2k's merges with linuxport are flagged as such so you can easily track this on http://trac.xbmc.org/timeline
