Add setcaps logic on the subpicture sink pad for configuring which subpicture format is arriving. Add the first piece of PGS subpicture handling by dumping the stream contents out to the terminal as the packets arrive. Add some more debug. Don't calculate the running time for our subpicture packets twice, once is enough.
