FLAC decoding error in frame header

[nogweii]

Possible error. Not sure who's fault it is, probably mine. I get it when trying to import the "Symphony of Science" album, for each song in the album.

[flac @ 0xef0b00] invalid sync code
[flac @ 0xef0b00] invalid frame header
[flac @ 0xef0b00] decode_frame() failed

Do you want to try a flac -t *.flac in the directory that contains the album?

(the -t will make flac test each file)

100% 'ok' report for the album. The entire output:

Would you be able to try metaflac next?

metaflac --list *.flac

That will output a lot of text to the console

[nogweii]

Huge as you said,

Hmmmm, okay flac doesn't seem to have a problem. Can you try running the following python script in the same directory as the audio files.

import glob
from mutagen.flac import FLAC
for f in glob.glob("*.flac"):
    print f
    a = FLAC(f)

mutagen is what beets uses to read and write metadata from audio files.

(this shouldn't do anything to your files, but make sure you have a backup just incase)

Thanks for helping diagnose, @samdoshi!

FWIW, this isn't related to beets reading the FLAC files' tags; it's errors logged by the Chromaprint fingerprinter tool (fpcalc). See beetbox/pyacoustid#15.

It's safe to ignore these messages, @evaryont. If you want to get rid of them, you can disable the chroma plugin. But it would still be interesting to know why fpcalc (which uses FFmpeg under the hood) doesn't like your files.
