0051 but may also be a value close to it like the PTS of the last
0052 decoded frame or the last PTS extracted by the PES parser.
0053
0054 Description
0055 -----------
0056
0057 This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders
0058 this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_PTS``
0059 control.
0060
0061 This ioctl call asks the Video Device to return the current PTS
0062 timestamp.
0063
0064 Return Value
0065 ------------
0066
0067 On success 0 is returned, on error -1 and the ``errno`` variable is set
0068 appropriately. The generic error codes are described at the
0069 :ref:`Generic Error Codes <gen-errors>` chapter.
