MovieWiz thumbnail memory problems revisited

[Dan Soussi]

Hi JW,
I've noted a couple of issues with MovieWiz memory usage I hope you can find some time to look at:
1. MovieWiz Plugin and Manager
Thumbnail images appear to consume their uncompressed bitmap image size. (e.g. a 100KB thumbnail can occupy 3MB+ of RAM). Thumbnails are loaded each time their entry is selected and never released. If like me, you have 500+ movies and each thumbnail is large, and want to scroll through each entry, MW memory use will exceed 1.8GB and unexpectedly fail.

2. MovieWiz Manager
Movie table memory is not released when switching from "Manage Content" tab to another tab. Further new memory is consumed when switching back to "Manage Content" tab for the same data.

Can you develop some smarts to avoid memory use getting out of control? Perhaps release oldest thumbnail memory after a certain amount is consumed?

MoviewWiz is now an essential tool in meeting my media centre needs. Please keep up the good work.

Cheers,
Dan

Thanks Dan. I'll take a look at the memory again once I am thru with the upgrade to WizMetadataGrabber. I have made several changes to the thumbnail logic and most likely have caused a bug.

Could you post what versions of MovieWiz, WizUiHelper and WizWebHelper you are using?

Thanks.

Hi JW,

I'm using the current MW release:
MovieWizManager - v1.0.5.0
MovieWiz - v1.0.24.0
WizUiHelper - v1.0.21.0
GBPVRPublic - v1.0.3071.28374
WizWebHelper - v1.0.11.0

Regards,

Try this version and see if memory looks better (at least on the plugin side). v1.0.24.4

I tried the new version and it crashed PVR when I tried to open the program (windows failure box). I went back to 1.0.24.0 and it works again. Do I need to update any of the DLL files? Here are my logs files if interested.

Thanks.

I think I missed a DLL in the install. Try this version instead.

Thanks! That worked. I too have many large thumbnails for my collection so I will monitor some of the mem usage. Lately, I have noticed the scrolling of the movies in the list has gotten bogged down. Takes awhile to go thru the list.

Hi JW,

This version looks like a backwards step. The thumbnails are seriously blurred (myopic). On the bright side, the memory usage of the plugin is under control. I miss my high resolution thumbnails!

I also noted that some of the thumbnails don't show up in the plugin, where they did before. All my thumbnails are embedded in the database.

The MW Manager memory usage has not changed. It consumes memory as before.

Cheers,

I can probably improve on this. As part of trying to manage the memory, I scaled down the memory footprint for the thumbnails and probably was a bit to aggressive. I'll take a look at improving this in the next version.

I also noted that some of the thumbnails don't show up in the plugin, where they did before. All my thumbnails are embedded in the database.

Is there any pattern related to which thumbnails are missing? I may need a log file to troubleshoot this problem. Let me take a look at the code and beef up logging so I can try and isolate the problem.

I have not looked at the manager yet, but it is on my list of things to do.

I located what I think is the problem with the thumbnails not displaying. Although all my entries have embedded thumbnails, it looks like the plugin is now going to the file location in imageSourceLocation instead. If this image has moved, it fails to display a thumbnail.
