Picture viewer plugin

[MaBo]

Nice work. Yesterday I installed the plugin and it worked directly and nicely. It is great to be able to view pictures via the PVR350 tv-out now as well. Switching to the videocard tv-out is needed less often.

However, I noticed that (both via the pvr tv-out and the video card tv-out) the pictures are stretched vertically. All the faces get longer and it seems everybody nees a few good meals. The effect is not large, but it is noticeable. Maybe you could zoom in or out until either the height or the width fill the screen...

A slideshow function would be very nice.

THanks for the great work,
MaBo

pbj: I'm working on caching already for the next release, and yes it does make a nice difference.

MaBo: I hadn't noticed stretching, I'll take a look.  
I should be able to implement a slide show after the next GBPVR release, sub is adding a feature I need.

I think resize with keeping aspect ratio should sort out the stretching? You just have to figure out if x or y should be the control for resizing.

Plugin looks good

Nice Plugin:

A slide show feature would be great.  It would also be great if you could pick a default mp3 from the Music Library to play as background music for the slide show (if there wasn't music playing already...).

A list view would be a great option to allow a picture to found quickly.

About the stretching. I remember having read somewhere that TV-pixels are NOT square, whereas monitor pixels are. Maybe that's the cause of the stretching.

Hi ecruos,

Love the plugin too, been using it since you first released it. One question though about the colours. I've found that the colours on pictures displayed through your plugin on an MVP are a bit wrong. For example, skin comes out a kind of purple, blueberry colour. When I'm using the hauppauge software (not very often now luckily) the colours are fine. Also when displayed on the PC end through GBPVR they are fine as well. It's just on the MVP end, and is very noticable. It happens on different MVPs connected to different TVs. Have you come across this before?

Cheers, Rob

Rob,

I have not actually used the plugin, but I had the same problem when I was coding a simple server for the MVP. It turned out to be an issue with the RGB to YUV conversion that I used, and I ended up replacing it with an integer approximation I found on MSDN:

Y = ( (  66 * R + 129 * G +  25 * B + 128) >> 8) +  16
U = ( ( -38 * R -  74 * G + 112 * B + 128) >> 8) + 128
V = ( ( 112 * R -  94 * G -  18 * B + 128) >> 8) + 128

Uisng this really improved the colors.

I don't know what GB-PVR uses to do the conversion, but maybe sub can comment on this...

Regards,

Jan

Yes, this probably the problem. I cant remember the exact algorithm and numbers I used - I'll take a look after work.

Version 1.3 of the Pictures plugin is now available to download.  PC users now have slideshows although this doesn't quite work on the MVP yet.

Took me a while to release this version... sorry!

- Changed name of Plugin to Picture Library
- Added Configurable Width Stretch Factor setting for displays which would otherwise warp pictures
- Implemented slide show (Space to start) - Doesn't currently work with MVP though
- Added option to sort lists alphabetically in config
- Added support for PageUp/Previous Track, PageDown/Next Track to page through the folder view.
- Added NumCachedThumbnails to Config.  At 300, the first 300 thumbnails will be loaded
 at a normal speed as they are displayed.  The next time they are displayed they will
 appear faster.  If you pass over more than 300 thumbnails, the last viewed thumbnails
 will be appear more slowly, when you return over them.  If you run out of memory, either
 reduce the number of images in a directory, or reeduce the NumCachedThumbnails number.
- Implemented thumbnail caching: once a thumbnail is displayed it stays in memory and is
 therefore rendered faster until NumCachedThumbnails is exceeded.  Improves folder view speed.
- Icon view is now optional (in Config), when turned off, pictures and folders are displayed in
 list mode.

I can't get this version to work at all with the MVP. It justforces a reboot of the MVP as soon as I select Pictures from the menu. Versions of software in use:

GBPVR - 1.7i (I can;t seem to download 1.8e at the moment
Hauppage:2.2.22146

Prevoius version of Pictures worked for some image folders but any with more than a few pictures crashed MVP
