Media Preview v184.108.40.206 (06/13/2012)
User request release:
Improved badly encoded file processing to further avoid black frames
The version of LAVF FFmpeg used until now was actually still the version as of 04/10/2012...so updated it as of 06/13/2012:
This fixes a bug where some DVD VOB files could be recognized as a VC-1 encoded file instead of MPEG-2, leading to an unrecoverable error
Patched it to let FFmpeg extract images from interlaced VC-1 encoded video file even if we get some grey clouds instead of a complete image
Added some functions to the config tool:
Windows XP only: users can change thumbnail size using Tweak UI. The Testing and Cache tab now has an option to handle this Tweak UI parameter
Windows Vista+ only: The Testing and Cache tab has a new button that forces Media Preview to search for every media files on local drives, generate thumbnails, and cache them. Handy for users having a lot of often updated partitions filled with video files!

Works the same way on XP and Vista+: only updates requested thumbnails instead of deleting the entire Thumbs.db cache file
Added an Advanced tab with features for power users and developers
Fully complied to Libavcodec LGPL licence and changed Media Preview licencing terms
Remains free for non-commercial use
Redistribution is forbidden without permission (it's mainly a way for me to trace where the app get uploaded)
Repackaging is forbidden without permission (I saw a portable version floating around, which is a nonsense for an app that must be integrated to the system...)
Again, special thanks to the administrator of Codec Guide for his numerous feedbacks. I also want to acknowledge JEEB, one of the administrators at CCCP for reminding me that proper software licencing does matter.
Media Preview v18.104.22.168 (05/01/2012)

Media Preview v18.104.22.168 (03/10/2012)
Initial release: Support of Windows Vista and 7. Thumbnail generation with image entropy and average luminance as validation metrics.
Since the advent of Windows XP in 2001, Windows Explorer has improved its usability by running a preview control system that let you get a glimpse at the content of your files while browsing and without having to open them. For media files, this is done by generating thumbnails replacing default icons.
But the default video thumbnail extractor of Microsoft generally does a lousy job at getting useful previews of your media files, mostly due to performance considerations. Nevertheless, computers have become powerful enough not to let the matter rest, and Media Preview can help them to provide you the best.
Supports The Key Media Formats
By default, Windows only supports the media file formats developped by Microsoft or for Quicktime, and ignores other popular media formats. Third-party media players fill the gap in terms of playback but usually let the preview functionality on the side-road.
Media Preview is here to bring to your computer the full preview capabilities for all of your media files.
Redefines The Uniqueness Of Your Media Files
While browsing TV series folders, you probably already got sets of identical thumbnails, where the default thumbnail extractor get stuck with the same title sequence.
Media Preview get over this by seeking another sequence of your media files to let you get more information out of them.
Windows comes in 2 different flavors, 32-bit and 64-bit versions, the later not being entirely backward compatible. And one of the main problems with third-party thumbnail extractors is that most only work on the 32-bit version.
Media Preview caters to every versions of Windows so that you won't feel cheated even if you opted for the more performing 64-bit version. Obviously, it also works seamlessly with your local and remote media files.
Avoids The Monochrome Symptom
The default video thumbnail extractor usually grabs the first frame of your media files, possibly leading to only display a collection of black thumbnails.
Media Preview is smart enough to detect image relevance using related metrics. If the extracted image is part of a shot transition, Media Preview will go seek the following scene to get a meaningful thumbnail.
Gets You Free Of System Constraints
While browsing, you probably encountered some issues like not being able to rename or move a file anymore, because the thumbnail extractor was still running in the background.
Media Preview won't ever remind you of its presence as you'll be able to do what you want with your files.
Designed For System Stability And Performance
Third-party thumbnail extractors use directly the video rendering pipelines of your system and so impose upon you the media solution it's tied to, sometimes invoking a full-blown framework to do the job.
Media Preview remains out of the regular rendering pipeline, lets your delicate playback setup stable and out of harm, doesn't clutter your system with more than needed, but still performs efficiently.
