An implementation of TagLib::File with MP4 specific methods.
This implements and provides an interface for MP4 files to the TagLib::Tag and TagLib::AudioProperties interfaces by way of implementing the abstract TagLib::File API as well as providing some additional information specific to MP4 files.
TagLib::MP4::File::File | ( | FileName | file, |
bool | readProperties = true, | ||
Properties::ReadStyle | audioPropertiesStyle = Properties::Average, | ||
ItemFactory * | itemFactory = nullptr ) |
Constructs an MP4 file from file. If readProperties is true
the file's audio properties will also be read.
The items will be created using itemFactory (default if null).
References TagLib::AudioProperties::Average.

TagLib::MP4::File::File | ( | IOStream * | stream, |
bool | readProperties = true, | ||
Properties::ReadStyle | audioPropertiesStyle = Properties::Average, | ||
ItemFactory * | itemFactory = nullptr ) |
Constructs an MP4 file from stream. If readProperties is true
the file's audio properties will also be read.
The items will be created using itemFactory (default if null).
References TagLib::AudioProperties::Average.

overridevirtual |
Destroys this instance of the File.
Reimplemented from TagLib::File.
|
overridevirtual |
Returns the MP4 audio properties for this file.
Implements TagLib::File.
bool TagLib::MP4::File::hasMP4Tag | ( | ) | const |
|
static |
Returns whether or not the given stream can be opened as an ASF file.

overridevirtual |
Implements the unified property interface – export function.
Reimplemented from TagLib::File.
Referenced by removeUnsupportedProperties().
|
overridevirtual |
Removes unsupported properties. Forwards to the actual Tag's removeUnsupportedProperties() function.
Reimplemented from TagLib::File.
References properties().

overridevirtual |
|
overridevirtual |
Implements the unified property interface – import function.
Reimplemented from TagLib::File.
bool TagLib::MP4::File::strip | ( | int | tags = AllTags | ) |
|
overridevirtual |
Returns a pointer to the MP4 tag of the file.
MP4::Tag implements the tag interface, so this serves as the reimplementation of TagLib::File::tag().
Implements TagLib::File.
