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.
