This works great when the mpegts file is 720p. However, if the input
mpegts is 1080i, the image appears to have the colors offset vertically.
I've attached a jpg grab as an example of what it looks like.
So, is this a user error (not putting in the correct command line
parameters)? A hardware problem? A hardware driver problem? A ffmpeg
problem? A limitation and stop attempting to transcode 1080i with v4l2m2m ?
