Having been happy when found a possibility to get the duration of a
mp3-file by just reading out 

 TMediaPlayer::Length

I finally found that this value is not always correct, at least not
for the vbr-files my mp3-recorder creates. In fact there was a huge
difference for a file which real duration was about 7h and
TMediaPlayer::Length holds a value about 4h.

Is there another possibility/library to get the exact duration of such
kind of mp3-files? 

(The motivation was to prefix the files being created with the
date/time when recording started. Unfortunately the files have a
time-stamp, when recording ended. So I had to calculate the
starting-time by substractiing the duration from the end-of-record.
Unfortunately the recorder only records in this
variable-bitrate-format.)

Thanks a lot,

MR
