Description
|
|
-----------
|
|
|
|
This ioctl is for Digital TV devices only. To control a V4L2 decoder use the
|
|
V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
|
|
|
|
This ioctl call suspends the live video stream being played. Decoding
|
|
and playing are frozen. It is then possible to restart the decoding and
|
|
playing process of the video stream using the VIDEO_CONTINUE command.
|
|
If VIDEO_SOURCE_MEMORY is selected in the ioctl call
|
|
VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data
|
|
until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
|
|
|
|
|
|
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.
