Help with transcoding h264 encoded TS on raspberry pi

[Stefan Simon]

I see, you get the width and height in prerolling, I only get it after the
pipeline is prerolled. Unfortunately, even when I encode the "sanitized"
video,  the bottom of the video is distorted with some kind of redish
ghosting... trying to figure out the problem, but my best bet might be
obtaining version 1.2...somehow :)
