Detailed Description
Implements decoding of FLAC audio files.

- FlacAudio
- Since
- 1.10.0

Constructor & Destructor Documentation
◆ FlacAudioCursor()
|
explicit |
Reads the .wav header from the indicated stream.
This leaves the read pointer positioned at the start of the data.
Definition at line 59 of file flacAudioCursor.cxx.
◆ ~FlacAudioCursor()
|
virtual |
xxx
Definition at line 91 of file flacAudioCursor.cxx.

Member Function Documentation
◆ read_samples()
|
virtual |
Read audio samples from the stream.
N is the number of samples you wish to read. Your buffer must be equal in size to N * channels. Multiple-channel audio will be interleaved.
Reimplemented from MovieAudioCursor.
Definition at line 122 of file flacAudioCursor.cxx.
◆ seek()
|
virtual |
Seeks to a target location.
Afterward, the packet_time is guaranteed to be less than or equal to the specified time.
Reimplemented from MovieAudioCursor.
Definition at line 105 of file flacAudioCursor.cxx.
