Bug Fixes in KDE Base
Show video previews according to file content instead of the mimetype-string
Show a video widget depending on the video content instead of the mimetype
string: There are container formats which can be either audios or videos.
Besides, the rmvb video files have a mimetype of
"application/vnd.rn-realmedia", and these files can be recognized as videos
