How to stretch a 4:3 Video to full screen (16:9)?

some of the videos are encoded in 4:3 format as visible on the screen. For the sake of uniformity we need to display every channel in a 16:9 format. Is there any way to convert (stretch) all the videos to one single format i.e 16:9

How can we stretch the video in roVideoPlayer?

That is a function that belongs on the display device and is usually there in the form of stretch or zoom or some such.

However since you asked about roVideoPlayer I think you are developing a channel and therefore this question really belongs in the developer forum.
