| - Returns the 33-bit timestamp 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. |
| |
| |
| Description |
| ----------- |
| |
| This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders |
| this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_PTS`` |
| control. |
| |
| This ioctl call asks the Video Device to return the current PTS |
| timestamp. |
| |
| |
| Return Value |
| ------------ |
| |
| On success 0 is returned, on error -1 and the ``errno`` variable is set |
| appropriately. The generic error codes are described at the |
| :ref:`Generic Error Codes <gen-errors>` chapter. |
