#define AUDIO_GET_PTS   _IOR('o', 19, __u64)

AUDIO_GET_PTS

Read the 33 bit presentation time stamp as defined in ITU T-REC-H.222.0 / ISO/IEC 13818-1.

The PTS should belong to the currently played frame if possible, but may also be a value close to it like the PTS of the last decoded frame or the last PTS extracted by the PES parser.
