/**
* SECTION:gupnp-dlna-video-information
* @short_description: Base class representing video metadata needed
* for DLNA profiles matching.
* @see_also: #GUPnPDLNABoolValue, #GUPnPDLNAFractionValue,
* #GUPnPDLNAIntValue, #GUPnPDLNAStringValue
*
* #GUPnPDLNAVideoInformation holds all video metadatas important for
* matching profiles. Note that it does not mean all data should be
* provided for every video file as in some cases it does not make
* sense (e.g. MPEG version does not make sense for Quicktime video
* files).
*
* For metadata attributes that do not exist in current video file an
* unset value should be returned. For metadata attributes that do
* exist a set value with proper underlying value should be
* returned. In case metadata extractor has completely no clue how to
* extract some metadata attribute at all, an unsupported value should
* be returned. Note that unsupported values should be a temporary
* mean before fixing the multimedia framework to be able to extract
* such attribute.
*
* Note that gupnp_dlna_video_information_get_mime() should always
* return a set value. Otherwise it is highly probably that the file
* will not match against any DLNA profile.
