Failed to tag MP4 file?
What does this mean?

INFO: Downloaded: 775.98 MB (00:58:36) @ 30.43 Mb/s (hvfxsd1/bi) [audio+video]

WARNING: Failed to tag MP4 file

I get this a few times but I don't know what it means to the resultant file.

Anyone help?

It usually happens if there's a problem with atomicparsley.

The resulting file should play ok, it just won't have any metadata.

Thanks John
