Minor fix for current ffprobe

[clort81]

in ffprobe_out_parser.py i had to change the parser for ffprobe output.

    for line in io.TextIOWrapper(process.stdout, encoding="utf-8"):
        ## ffprobe will return the time in ms and the size in bytes.
        if line.strip():  # Check if the line is not empty                                                                                                                       
            dts_time, packet_size = line.strip().split(",", 2)[:2]   # grab only 2 fields
             # original bad code dts_time, packet_size = line.strip().split(",")

It was choking on empty lines and for some reason ffprobe was returning lines with a trailing comma. This gets past that problem.

Thanks for the real hepful tool!
