Description |
|
----------- |
|
|
|
This ioctl is obsolete. Do not use in new drivers. It has been replaced |
|
by the V4L2 ``V4L2_CID_MPEG_AUDIO_DEC_MULTILINGUAL_PLAYBACK`` control |
|
for MPEG decoders controlled through V4L2. |
|
|
|
This ioctl call asks the Audio Device to select the requested channel |
|
for bilingual streams if possible. |
|
|
|
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.
