Arguments
|
|
---------
|
|
|
|
``fd``
|
|
File descriptor returned by :c:func:`open() <dvb-dmx-open>`.

|
|
Array used to store 5 Program IDs.

|
Description
|
|
-----------
|
|
|
|
This ioctl allows to query a DVB device to return the first PID used
|
|
by audio, video, textext, subtitle and PCR programs on a given service.
|
|
They're stored as:
|
|
|
|
======================= ======== =======================================
|
|
PID element position content
|
|
======================= ======== =======================================
|
|
pids[DMX_PES_AUDIO] 0 first audio PID
|
|
pids[DMX_PES_VIDEO] 1 first video PID
|
|
pids[DMX_PES_TELETEXT] 2 first teletext PID
|
|
pids[DMX_PES_SUBTITLE] 3 first subtitle PID
|
|
pids[DMX_PES_PCR] 4 first Program Clock Reference PID
|
|
======================= ======== =======================================
|
|
|
|
|
|
.. note::
|
|
|
|
A value equal to 0xffff means that the PID was not filled by the
|
|
Kernel.
|
|
|
|
|
|
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.
