Constructs an MP4 file from stream. More... | |
virtual | ~File () |
Destroys this instance of the File. More... | |
Tag * | tag () const |
Returns a pointer to the MP4 tag of the file. More... | |
PropertyMap | properties () const |
Implements the unified property interface – export function. More... | |
void | removeUnsupportedProperties (const StringList &properties) |
Removes unsupported properties. More... | |
PropertyMap | setProperties (const PropertyMap &) |
Implements the unified property interface – import function. More... | |
Properties * | audioProperties () const |
Returns the MP4 audio properties for this file. More... | |
bool | save () |
Save the file. More... | |
bool | hasMP4Tag () const |
Returns whether or not the file on disk actually has an MP4 tag, or the file has a Metadata Item List (ilst) atom. More... | |
![]() | |
FileName | name () const |
Returns the file name in the local file system encoding. More... | |
PropertyMap | properties () const |
Exports the tags of the file as dictionary mapping (human readable) tag names (uppercase Strings) to StringLists of tag values. More... | |
void | removeUnsupportedProperties (const StringList &properties) |
Removes unsupported properties, or a subset of them, from the file's metadata. More... | |
PropertyMap | setProperties (const PropertyMap &properties) |
Sets the tags of this File to those specified in properties. More... | |
ByteVector | readBlock (unsigned long length) |
Reads a block of size length at the current get pointer. More... | |
void | writeBlock (const ByteVector &data) |
Attempts to write the block data at the current get pointer. More... | |
long | find (const ByteVector &pattern, long fromOffset=0, const ByteVector &before=ByteVector()) |
Returns the offset in the file that pattern occurs at or -1 if it can not be found. More... | |
long | rfind (const ByteVector &pattern, long fromOffset=0, const ByteVector &before=ByteVector()) |
Returns the offset in the file that pattern occurs at or -1 if it can not be found. More... | |
void | insert (const ByteVector &data, unsigned long start=0, unsigned long replace=0) |
Insert data at position start in the file overwriting replace bytes of the original content. More... | |
void | removeBlock (unsigned long start=0, unsigned long length=0) |
Removes a block of the file starting a start and continuing for length bytes. More... | |
bool | readOnly () const |
Returns true if the file is read only (or if the file can not be opened). More... | |
bool | isOpen () const |
Since the file can currently only be opened as an argument to the constructor (sort-of by design), this returns if that open succeeded. More... | |
bool | isValid () const |
Returns true if the file is open and readable. More... | |
void | seek (long offset, Position p=Beginning) |
Move the I/O pointer to offset in the file from position p. More... | |

TagLib::MP4::File::File | ( | FileName | file, |
bool | readProperties = true , |
||
Properties::ReadStyle | audioPropertiesStyle = Properties::Average |
||
) |
Constructs an MP4 file from file.
If readProperties is true the file's audio properties will also be read.
TagLib::MP4::File::File | ( | IOStream * | stream, |
bool | readProperties = true , |
||
Properties::ReadStyle | audioPropertiesStyle = Properties::Average |
||
) |
|
virtual |
Destroys this instance of the File.
Reimplemented from TagLib::File.
|
virtual |
Returns the MP4 audio properties for this file.
Implements TagLib::File.
bool TagLib::MP4::File::hasMP4Tag | ( | ) | const |
PropertyMap TagLib::MP4::File::properties | ( | ) | const |
Implements the unified property interface – export function.
void TagLib::MP4::File::removeUnsupportedProperties | ( | const StringList & | properties | ) |
Removes unsupported properties.
Forwards to the actual Tag's removeUnsupportedProperties() function.
|
virtual |
PropertyMap TagLib::MP4::File::setProperties | ( | const PropertyMap & | ) |
Implements the unified property interface – import function.
|
virtual |
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.
