Hello all , i am using this code for a video streaming of the application, In the same i am able to stream the required video but the video does not gets displayed on to my device or simulator. I believe that there would be some issues with the video API being used but am unable to check it out... It will be of great help if you share yours views on the above lines of code.

Thanks
