Hi ,

Have gone through the article which displays video ,
I have been doing the R&D almost for 3 weeks now always got stuck in playlist area.

Mentioned below are the steps involved:

1) I have a list of videos/audios (of any format mpeg|.mp3|.m3u|.aac|.aif|.iff|.mid|.midi|.mpa|.ra|.ram|.wav|.wma
.wmv|.mpg|.3gp|.asf|.asx|.avi|.mov|.mp4|.qt|.rm|.swf|)
2)User selects any of this files and clicks on play button
3)so accordingly i need to dipaly the video / audio file on webpage
4)Also he has the option to include files in playlist which will execute the files one after the other.

Now my problem is with WMPlayer u can run some specific files/Quicktime can run some specific files/Real player can run some specific files.

Need to know which player to use so that it can deal with maximum of formats.
Also it would be great if you could assist me achieving the desired output .

Any help will be greatly appreciated.
