Detailed Description

Wrapper class for GstTagList.

TagList is a collection of tags and values that is associated with TagMessages and TagEvents. used to describe metadata in media files.

Tags are usually set with the helper functions:

TagList tl();
tl.setTitle("12th Symphony");
tl.setAuthor("Beethoven");
tl.setTrackNumber(1);

And retrieved as native Qt types in a similar way:

qDebug() << tl.title();
int track = tl.trackNumber();

Some tags accept multiple values. By default only the first value is returned, but it is possible to determine the number of values available and retrieve a specific one using its index:

int authors = tl.authorCount();
for (int i=0; i<authors; i++) {
myAuthorList << tl.author(i);
}

It is also possible to use the optional TagMerge parameters when setting tags that accept multiple values:

tl.setAuthor("John");
tl.setAuthor("Mary", QGst::TagMergeAppend); //now tl.authorCount() equals 2
tl.setAuthor("George", QGst::TagMergeReplaceAll); //now there is only one author, "George"
Note
This class is implicitly shared.
