Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38 ("docs: Create a user-space API guide").
As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.
Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

Description
|
|
-----------
|
|
|
|
This ioctl call allows to remove a PID when multiple PIDs are set on a
|
|
transport stream filter, e. g. a filter previously set up with output
|
|
equal to :c:type:`DMX_OUT_TSDEMUX_TAP <dmx_output>`, created via either
|
|
:ref:`DMX_SET_PES_FILTER` or :ref:`DMX_ADD_PID`.
|
|
|
|
|
|
Return Value
|
|
------------
|
|
|
|
On success 0 is returned.
|
|
|
|
On error -1 is returned, and the ``errno`` variable is set
|
|
appropriately.
|
|
|
|
The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
