|
- 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This ioctl is obsolete.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this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_PTS`` |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.
