Detailed Description

An implementation of TagLib::File with some helpers for Ogg based formats.

This is an implementation of Ogg file page and packet rendering and is of use to Ogg based formats. While the API is small this handles the non-trivial details of breaking up an Ogg stream into packets and makes these available (via subclassing) to the codec metadata implementations.

Constructor & Destructor Documentation

◆ ~File()

TagLib::Ogg::File::~File ( )

overridevirtual

Destroys this File instance.

Reimplemented from TagLib::File.

Reimplemented in TagLib::Ogg::Opus::File, TagLib::Ogg::Speex::File, and TagLib::Ogg::Vorbis::File.

◆ File() [1/3]

TagLib::Ogg::File::File ( const File & )

delete

◆ File() [2/3]

TagLib::Ogg::File::File ( FileName file )

protected

Constructs an Ogg file from file.

Note: This constructor is protected since Ogg::File shouldn't be instantiated directly but rather should be used through the codec specific subclasses.

◆ File() [3/3]

TagLib::Ogg::File::File ( IOStream * stream )

protected

Constructs an Ogg file from stream.

Note: This constructor is protected since Ogg::File shouldn't be instantiated directly but rather should be used through the codec specific subclasses.; TagLib will not take ownership of the stream, the caller is responsible for deleting it after the File object.

Member Function Documentation

◆ firstPageHeader()

const PageHeader * TagLib::Ogg::File::firstPageHeader ( )

Returns a pointer to the PageHeader for the first page in the stream or null if the page could not be found.

◆ lastPageHeader()

const PageHeader * TagLib::Ogg::File::lastPageHeader ( )

Returns a pointer to the PageHeader for the last page in the stream or null if the page could not be found.

◆ operator=()

File & TagLib::Ogg::File::operator= ( const File & )

delete

◆ packet()

ByteVector TagLib::Ogg::File::packet ( unsigned int i )

Returns the packet contents for the i-th packet (starting from zero) in the Ogg bitstream.

Warning: This requires reading at least the packet header for every page up to the requested page.

◆ save()

bool TagLib::Ogg::File::save ( )

overridevirtual

Save the file and its associated tags. This should be reimplemented in the concrete subclasses. Returns true if the save succeeds.

Warning: On UNIX multiple processes are able to write to the same file at the same time. This can result in serious file corruption. If you are developing a program that makes use of TagLib from multiple processes you must insure that you are only doing writes to a particular file from one of them.

Implements TagLib::File.
