Hello Experts,

I hope you are all fine and doing well..

I am in a big trouble here and need some assistance from your side.

I am developing a J2Me mobile app in which I have to play videos from Amazon Cloud Signed Url. I have gone through all the internet resources and tested them but no one is working for me at all. Infact I am not even able to play normal video (mp4,3gp) urls also. I am not sure what I am missing the code. I am pasting my code below.

Question: 1. What format can a J2Me player play.
2. Is it possible at all to play signed url or not.
3. Can I stream using Amazon signed/unsigned url on J2Me device.

Please provide me working sample code if possible. I have tried all internet resources they don't work at all on the phones. The only code which works on simulator is the one with mpg file... but that doesn't work on the phone.

Here is the code. This one plays mpg video on simulator but not on phone. But i need to play mp4 or 3gp or flv
