Frame Reader Initialization

The documentation for the frame reader is a bit confusing. They do not give any examples for color planes in sequence. I have only ever used it with color planes in parallel, so I couldn't say for sure if your settings are correct.

I noticed you have your output set to interlaced. Are you trying to output interlaced video from the frame reader as well? I don't see anywhere in the documentation where it explicitly mentions interlaced support for the frame reader. I don't know for sure, but I suspect the frame reader does not support interlaced output.
