- \class QMediaResource
- \preliminary
- \since 4.7
- \brief The QMediaResource class provides a description of a media resource.
- \ingroup multimedia
-
- 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().
