| 44 | The PTS should belong to the currently played frame if possible, | |
| 45 | but may also be a value close to it like the PTS of the last | |
| 46 | decoded frame or the last PTS extracted by the PES parser. | |

| 56 | This ioctl call asks the Audio Device to return the current PTS | |
| 57 | timestamp. | |
