Usage

After installation you can insert videoplayers on wiki pages using normal wiki-syntax: [[File:Video.mp4]].

Video player code is embedded anywhere (including Image Page) except Image Galleries and when size is set less than $wgMinFLVSize[] = array(180,180) by default. In Image Galleries, a «filmstrip» icon is also shown below each video to distinguish between videos and images.
Some error message formatting.
English+Russian i18n.
Removed commented out legacy-code (no hooks at all!).
Ability to set $wgFLVConverters and $wgFLVProbes before the inclusion of FlvHandler.php.
Automatic prepending of $wgFlashPlayer with MediaWiki script path ($wgScriptPath).
Support for any Unicode video file names (r3 can not download files with non-latin1 filenames).
Collages of 4 frames as previews when size is more than $wgMinFLVSize.
Modified FlvHandler is free of errors «frame size must be a multiple of 2» generated by ffmpeg, because the frame is extracted, and THEN resized using ImageMagick.
Flow player 3.1.3 bundled.

Return these changes back to trunk.

Install ffmpeg on your server (see also window$ version) and make sure it’s in PATH environment variable.
Then as usual put require_once "$IP/extensions/FlvHandler/FlvHandler.php"; to your LocalSettings.php.
To disable embedding of video player code on image galleries and image pages, you need to apply 1-line patches to ImageGallery.php and ImagePage.php:

patch includes/ImagePage.php < extensions/FlvHandler/ImagePage.php.diff
patch includes/ImageGallery.php < extensions/FlvHandler/ImageGallery.php.diff
