The mp3 encoder you used wrote the BPM as a comment (that may or may not be correct) into the file you read with FFmpeg, FFmpeg shows the comment. > For example, the following command: > > ffmpeg -i ~/Music/Archive.org/Jumpin\'\ at\ the\ Woodside\ -\ Count\ > Basie\ And\ His\ Orchestra.mp3 -f ffmetadata jumpin_metadata.txt > > Produces useful output of the (shortened) form: > Input #0, mp3, from '/home/adam/Music/Archive.org/Jumpin' at the > Woodside - Count Basie And His Orchestra.mp3': > Metadata: > album : Jumpin' at the Woodside > title : Jumpin' at the Woodside > TLEN : 196.48 > artist : Count Basie And His Orchestra;Count Basie > track : 01 > encoder : LAME 64bits version 3.99.5 (http://lame.sf.net) > TBPM : 2 > > (Where TBPM is the bpm tag). > > Unfortunately, when I try to use a similar command with any other audio > format (such as ALAC, FLAC, or M4A), ffmpeg doesn't appear to return any > BPM information. > This is true even for files which I can verify (with other > tools) that they have bpm/tempo metadata attached. Command line and complete, uncut console output missing / please provide such a file.
