For Mediaportal 1.11
svn 26443 Mantis #0003047: additional bugfix for GUITextureManager

For Mediaportal 1.20
svn 26448 Mantis #0003047: additional bugfix for GUITextureManager

Only this svn changes causes the problem.

ok so the original patch was fine but the aditional bugfix created the problem? That wil give me some better understanding.

You are right. Only these addional changes causes this behaviour for me. Without it everything works fine. I tested both Mediaportal 1.11 and Mediaportal 1.20 with and without it.

Hi all,
I've discussed this problem with armandp (thx for this) before, because without the additional changes some plugins (e.g. WorldClock, SysInfo) doesn't work anymore. I'm confident that armandp can find a best solution for all in the next few days.

Cheers, Micropolis ;-)

I've discussed this problem with armandp (thx for this) before, because without the additional changes some plugins (e.g. WorldClock, SysInfo) doesn't work anymore.

After reading your statement that the patch causes also trouble with other plugins I made further tests. Lately I had trouble with dropped frames within Mediaportal all the time. In video and TV mode frames were dropped nearly every minute (every 1000-2000 frames I had 1-2 dropped frames). After experiencing the dropped frames with high resolution subtitles and reverting the additional bugfix I made another attempt and removed everything related to mantis 3047 and compiled a new 1.20 build.

I started a HDTV-channel and pressed Shift+1 to see if frames are still dropped.

After more than 150.000 drawn frames I can report that this randomly stutter is gone now. 0 dropped frames after more than 50 minutes! Everything is smooth and stable as it should be. I am very glad now.

My video cover change problem resolved in 26443 so you can forget my observation from my previous post.

Aha - now I know where the dropped frames every minute come from (I already blamed Alex´s HTPCInfo)! for your findings!
Think it´s time to revert this one

 

[armandp]

Good news i found a better way to resolve the deadlock without the other changes - in the next hours i will post 6 DLL's (3 versions for each revision: 1.1.1 and 1.2.0).

Version 1: Reverted all changes on GUITextureManager and related classes (so the blank 'before' situation)
Version 2: Deadlock fix
Version 3: Deadlock fix with faster cache lookup

once i post these dll's i want to ask you to compare them in terms of measured performance like the dropped frames and the GUI experience overall.
