Description |
|
----------- |
|
|
|
This ioctl selects which sub-stream is to be decoded if a program or |
|
system stream is sent to the video device. If no audio stream type is |
|
set the id has to be in [0xC0,0xDF] for MPEG sound, in [0x80,0x87] for |
|
AC3 and in [0xA0,0xA7] for LPCM. More specifications may follow for |
|
other stream types. If the stream type is set the id just specifies the |
|
substream id of the audio stream and only the first 5 bits are |
|
recognized. |
|
|
|
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.
