Rename QtMultimediaKit to QtMultimedia.
There are a few legacy bits left in place so it passes CI, and then qt5.git etc can be updated. Change-Id: I6b082e50e6958c72fdabc2974992e16d90dafa3a Reviewed-on: http://codereview.qt-project.org/5368 Reviewed-by: Qt Sanity Bot <qt_sanity_bot@ovi.com> Reviewed-by: Jonas Rabbe <jonas.rabbe@nokia.com>

\class QAudioCaptureSource
|
||||
\brief The QAudioCaptureSource class provides an interface to query and select an audio input endpoint.
|
||||
\inmodule QtMultimedia
|
||||
\ingroup multimedia
|
||||
\since 1.0
|
||||
|
||||
QAudioCaptureSource provides access to the audio inputs available on your system.
|
||||
|
||||
You can query these inputs and select one to use.
|
||||
|
||||
A typical implementation example:
|
||||
\snippet doc/src/snippets/multimedia-snippets/media.cpp Audio capture source
|
||||
|
||||
The audiocapturesource interface is then used to:
|
||||
|
||||
- Get and Set the audio input to use.
|
||||
|
||||
The capture interface is then used to:
|
||||
|
||||
- Set the destination using setOutputLocation()
|
||||
|
||||
- Set the format parameters using setAudioCodec(),
|
||||
|
||||
- Control the recording using record(),stop()
