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>

|

\brief The QMediaResource class provides a description of a media resource.
|
||||
\inmodule QtMultimedia
|
||||
\ingroup multimedia
|
||||
\since 1.0
|
||||
|
||||
A media resource is composed of a \l {url()}{URL} containing the
|
||||
location of the resource and a set of properties that describe the
|
||||
format of the resource. The properties provide a means to assess a
|
||||
resource without first attempting to load it, and in situations where
|
||||
media be represented by multiple alternative representations provide a
|
||||
means to select the appropriate resource.
|
||||
|
||||
Media made available by a remote services can often be available in
|
||||
multiple encodings or quality levels, this allows a client to select
|
||||
an appropriate resource based on considerations such as codecs supported,
|
||||
network bandwidth, and display constraints. QMediaResource includes
|
||||
information such as the \l {mimeType()}{MIME type}, \l {audioCodec()}{audio}
|
||||
and \l {videoCodec()}{video} codecs, \l {audioBitRate()}{audio} and
|
||||
\l {videoBitRate()}{video} bit rates, and \l {resolution()}{resolution}
|
||||
so these constraints and others can be evaluated.
|
||||
|
||||
The only mandatory property of a QMediaResource is the url().
