Member Function Documentation

◆ applyChanges()

void TagParser::MediaFileInfo::applyChanges	(	Diagnostics &	diag,
		AbortableProgressFeedback &	progress )

Applies assigned/changed tag information to the current file.

This method applies previously assigned tag information to the current file.

Depending on the changes to be applied the file will be rewritten.

When the file needs to be rewritten it will be renamed. A new file with the old name will be created to replace the old file.

Exceptions

Throws	std::ios_base::failure when an IO error occurs.
Throws	TagParser::Failure or a derived exception when a making error occurs.

Remarks: Tags and tracks need to be parsed without errors before this method can be called. All previous parsing results are cleared (using clearParsingResults()). Hence the file must be reparsed. All related objects (tags, tracks, ...) might get invalidated. This includes notifications of these objects as well.

See also: clearParsingResults()

This allows a rescan of the file using parsing methods like parseContainerFormat(). Otherwise, these methods do nothing if the information to be parsed has already been gathered.

Remarks: Any pointers previously returned by tags(), tracks(), ... object should be considered invalidated.

Definition at line 1378 of file mediafileinfo.cpp.

◆ container()

AbstractContainer * TagParser::MediaFileInfo::container ( ) const

inline

Returns the container for the current file.

If there is not corresponding subclass of AbstractContainer for the container format or the container has not been parsed yet using the parseContainerFormat() method nullptr will be returned.

◆ createAppropriateTags()

bool TagParser::MediaFileInfo::createAppropriateTags ( const TagCreationSettings & settings = TagCreationSettings() )

Ensures appropriate tags are created according the given settings.

Returns: Returns whether appropriate tags could be created for the file.

Remarks

Tags must have been parsed before invoking this method (otherwise it will just return false).
The ID3 related arguments are only practiced when the file format is MP3 or when the file format is unknown and treatUnknownFilesAsMp3Files is true.
Tags might be removed as well. For example the existing ID3v1 tag of an MP3 file will be removed if id3v1Usage is set to TagUsage::Never.
The method might do nothing if present tag(s) already match the given specifications.
This is only a convenience method. The task could be done by manually using the methods createId3v1Tag(), createId3v2Tag(), removeId3v1Tag() ... as well.
Some tag information might be discarded. For example when an ID3v2 tag needs to be removed (TagSettings::id3v2usage is set to TagUsage::Never) and an ID3v1 tag will be created instead not all fields can be transferred.

Definition at line 616 of file mediafileinfo.cpp.

◆ createId3v1Tag()

Creates an ID3v1 tag for the current file.

This method does nothing the tags of the current file haven't been parsed using the parseTags() method.

If the file has already an ID3v1 tag no new tag will be created.

See also: applyChanges()

Definition at line 1071 of file mediafileinfo.cpp.

◆ createId3v2Tag()

To apply the created tag and other changings call the applyChanges() method.

Returns: Returns the first ID3v2 tag of the current file.

See also: applyChanges()

Definition at line 1138 of file mediafileinfo.cpp.

◆ createVorbisComment()

std::uint64_t TagParser::MediaFileInfo::maxFullParseSize ( ) const

inline

Returns the maximal file size for a "full parse" in byte.

Remarks: So far this is Matroska-specific: The "Tags" element (which holds the tag information) is commonly at the end of a Matroska file. Hence the parser needs to walk through the entire file to find the tag information if no "SeekHead" element is present which might causes long loading times. To avoid this a maximal file size for a "full parse" can be specified. The disadvantage is that the parser relies on the presence of a SeekHead element on larger files to retrieve tag information.

The default value is 50 MiB.

Definition at line 745 of file mediafileinfo.h.

◆ maxPadding()

std::size_t TagParser::MediaFileInfo::maxPadding ( ) const

inline

Returns the maximum padding to be written before the data blocks when applying changes.

Maximum padding in front of the file allows adding additional fields afterwards without needing to rewrite the entire file or to put tag information at the end of the file.

The default value is 0 which will force the library to rewrite the entire file almost always when applying changes. Increate the value using setMaxPadding() to prevent this.

See also: minPadding(); tagPosition(); setMaxPadding()

Definition at line 611 of file mediafileinfo.h.

◆ mergeId3v2Tags()

void TagParser::MediaFileInfo::mergeId3v2Tags ( )

Merges the assigned ID3v2 tags into a single ID3v2 tag.

Some files I've got contain multiple successive ID3v2 tags. If the tags of such an file is parsed by this class, these tags will be kept separate. This method merges all assigned ID3v2 tags. All fields from the additional ID3v2 tags will be inserted to the first tag. All assigned ID3v2 tag instances except thefirst will be destroyed.

A possibly assigned ID3v1 tag remains unaffected.

This method does nothing the tags of the current file haven't been parsed using the parseTags() method.

Definition at line 1425 of file mediafileinfo.cpp.

◆ mimeType()

string_view TagParser::MediaFileInfo::mimeType ( ) const

◆ minPadding()

std::size_t TagParser::MediaFileInfo::minPadding ( ) const

inline

Returns the minimum padding to be written before the data blocks when applying changes.

See also: maxPadding(); tagPosition(); setMinPadding()

Definition at line 583 of file mediafileinfo.h.

◆ mp4Tag()

◆ setSaveFilePath() [2/2]

void TagParser::MediaFileInfo::setSaveFilePath ( std::string_view saveFilePath )

inline

Sets the "save file path".

If saveFilePath is not empty, this path will be used to save the output file when applying changes using applyChanges(). Thus the current file is not modified by applyChanges() in this case and the variable isForcingRewrite() does not affect the behaviour of applyChanges(). If the changes have been applied without fatal errors the "save file path" is cleared and used as the new regular path().

By default, this path is empty.
