flacenc

flacenc encodes FLAC streams. FLAC is a Free Lossless Audio Codec. FLAC audio can directly be written into a file, or embedded into containers such as oggmux or matroskamux.

Example launch line

 gst-launch-1.0 audiotestsrc num-buffers=100 ! flacenc ! filesink location=beep.flac

Encode a short sine wave into FLAC

 gst-launch-1.0 cdparanoiasrc mode=continuous ! queue ! audioconvert ! flacenc ! filesink location=cd.flac

Rip a whole audio CD into a single FLAC file, with the track table saved as a CUE sheet inside the FLAC file

 gst-launch-1.0 cdparanoiasrc track=5 ! queue ! audioconvert ! flacenc ! filesink location=track5.flac

Rip track 5 of an audio CD and encode it losslessly to a FLAC file
