readMetadata returns wrong duration

[M4dhav]

In my usage of this package, I noticed that the readMetadata function returned the wrong duration, but for a specific mp3 file. I tested it with some other mp3 files and it seemed to return the correct durations. I believe this might be an edge case worth looking at.

If possible, I'd like to investigate this issue myself to learn more about how media parsing works. Could someone please guide me a bit as to what exactly I should be looking for here when trying to solve this?

Hi!

Sorry for the delay and thank you for the
If you still want to investigate, you should check this file : lib/src/parsers/id3v2.dart.

It's the code that decode the metadata of a MP3. At line 265 and 277, there are the 2 methods what we use to compute the duration. Sometimes the metadata itself contains the duration in the tag TLEN.
