---------------------------------
Summary: Mp3Parser cannot extract the duration of an audio file
Key: TIKA-991
URL: https://issues.apache.org/jira/browse/TIKA-991
Project: Tika
Issue Type: Improvement
Components: parser
Affects Versions: 1.2
Reporter: Oliver Heger
The duration of an MP3 file is an important information. Currently,
{{Mp3Parser}} is not able to extract this data from a file.
Unfortunately, it is not easy to implement this functionality with the current
design of the {{Mp3Parser}} class. In order to obtain the duration, all audio
frames have to be read, and their durations have to be summed up. Currently,
only the beginning (the ID3v2 tags) and the end (lyrics and ID3v1) are
evaluated. Processing the whole file would have additional benefits, e.g. MP3s
with variable bit rates could be detected.
