42 - File descriptor returned by a previous call to open().
48 - Equals VIDEO_GET_PTS for this command.
54 - Returns the 33-bit timestamp as defined in ITU T-REC-H.222.0 /

65 This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders
66 this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_PTS``
