The JW-Player's JavaScript API allows for massive control over the JW player, including creating/accessing playlists in JavaScript. my Xwiki integration of JWPlayer improves on the original examples because it also runs correctly on Linux/FF3; the suggested examples http://home5.inet.tele.dk/nyboe/flash/mediaplayer4/JW_API_xmpl_5-2-4-0.html and http://home5.inet.tele.dk/nyboe/flash/mediaplayer4/JW_API_xmpl_6-2-0-0.html don't work on Linux/FF3, due to missing name (id only) on the embedded player in the original examples which I force in JWPlayer2 macro-doc. Note that setting durations shorter than remaining length, for videos or audio, doesn't seem to work, both for this and JWPlayer PL_Test. Still-images show for the correct duration, however. Is the inability to clip a time-based media file a JW-Player 4.x bug?
