[MEncoder-users] Runtime Incorrect

[Chris Nagele]

I am trying to grab the runtime from certain files. For some reason it does
not work anymore on simple Mp3 files.

It is showing me "ID_LENGTH=1085.00" when in reality the song is only 02:17.
Are there certain cases where the correct runtime cannot be calculated?
