Sure, but this is nothing we can merge upstream. You have to fill all
the fields and make sure they are fully usable. It's a lot more work.
Someone need to take ownership of this task.

Remember that using gst_video_info_parse_from_string() is not valid for
 anything non video/x-raw, which your code seems to do.
