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This ioctl is obsolete.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this ioctl has been replaced by the ``V4L2_CID_MPEG_VIDEO_DEC_FRAME`` |
|
control. |
|
|
|
This ioctl call asks the Video Device to return the number of displayed |
|
frames since the decoder was started. |
|
|
|
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.
