I tried playing a video file from "http" server. The video first downloaded and then played in my midlet. Then I used progressive download method. In my JAD file I used the attribute Progressive-Download= true and url= "http://www.xyz.com/video.3gp?streamable=true". But there was no change. I mean in both the cases the file took very long to start playing (the file size was 2MB).
I am not sure if this is the correct method to implement progressive download.
