There are a few multimedia web applications like PHPMotion, ClipBucket that allow playback of multimedia files.
Beside the mentioned multimedia web applications, are there other similar multimedia web applications that are resource-efficient, awesome playback speed (no play-stop-play-stop) and have many features like those in JPlayer?
It should support at least 3 different type of media format (e.g. mp4, flv)
UPDATE
As it seems that multimedia web applications are quite rare. I am also open for Multimedia Javascript Player. (Multimedia Player "made of" Javascript)
