Well, there is one way to fix it - read the entire MP3 file at once
(since you only really care about the length of a file which you
already have all of) and counting each frame, without looking at the
bitrate. But for players which treat files and streams identically, I
guess an iffy time display is quite a way down on the list of sins.
Mind, there's no excuse whatsoever for my portable MP3 player getting
it wrong. ;-)
Is it a
variable-rate MP3, by any chance? In which case, it's probably
dividing the length of the song in bytes by the bitrate of the first
frame; no really good way to fix that, other than by recording the
real song length (or mean bitrate) somewhere else.
I'm sure there is a good way to fix that, just few players implement
it. I'm sure the length can be found in some header or tag or
something. Foobar2k manages to show it correctly, so should others.
