The Digital TV audio device controls the MPEG2 audio decoder of the Digital
|
|||
|
|
TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
|
|||
|
|
types and ioctl definitions can be accessed by including
|
|||
|
|
``linux/dvb/audio.h`` in your application.
|
|||
|
|
|
|||
|
|
Please note that some Digital TV cards don’t have their own MPEG decoder, which
|
|||
|
|
results in the omission of the audio and video device.
|
|||
|
|
|
|||
|
|
These ioctls were also used by V4L2 to control MPEG decoders implemented
|
|||
|
|
in V4L2. The use of these ioctls for that purpose has been made obsolete
|
|||
|
|
and proper V4L2 ioctls or controls have been created to replace that
|
|||
|
|
functionality.
