Detailed Description

libFLAC decoder.

The decoder supports raw FLAC data (as found in .flac files) or FLAC streams inside an Ogg container (as found in .ogg or .oga files.) The format can be automatically detected if the input is seekable.

Note

For Ogg support to work, libFLAC must have been built with Ogg support.

Member Enumeration Documentation

FileFormat

enum class Aulib::DecoderFlac::FileFormat

strong

Format of the input file.

Enumerator
Detect	Try and detect the format. Only works if the input is seekable.
Flac	Assume input is raw FLAC.
Ogg	Assume input is FLAC data inside an Ogg container.
