Description
|
2016-07-05 18:58:48 +08:00
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
This ioctl call asks the Audio Device to bypass the Audio decoder and
|
|
|
|
|
forward the stream without decoding. This mode shall be used if streams
|
|
|
|
|
that can’t be handled by the DVB system shall be decoded. Dolby
|
|
|
|
|
DigitalTM streams are automatically forwarded by the DVB subsystem if
|
|
|
|
|
the hardware can handle it.
