The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Description
|
|
-----------
|
|
|
|
This ioctl is for DVB devices only. To control a V4L2 decoder use the
|
|
V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
|
|
|
|
This ioctl call asks the Video Device to stop playing the current
|
|
stream. Depending on the input parameter, the screen can be blanked out
|
|
or displaying the last decoded frame.
|
|
|
|
|
|
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.
