Added support for "video signal type present" information. The "Video signal type present" information is written to the output video file when it is created, and later is used by the decoder to properly decode the compressed video data. The saved attributes are: - format type (PAL, NTSC, etc.) - color primaries (BT709, SMPTE170M, etc.) - transfer characteristics (BT709, SMPTE170M, etc.) - color matrix ((BT709, SMPTE170M, etc.) These modifications allow the client to specify these attributes and, if specified, makes sure they are written to the output file.
