Provides a Java API for parsing MP4 files.

Provides a Java API for parsing MP4 files.

The isoparser API can read and write the MP4 file structure. It is a low level tool dealing with the so called boxes but it is as well as dealing with structures like tracks and movies.

The Iso Viewer helps to visualize the MP4 box structure. It is available as a Java Webstart application and as well as download.

The project home is https://github.com/sannies/mp4parser

Typical tasks for the MP4 Parser are:

  • Muxing audio/video into an MP4 file
  • Append recordings that use same encode settings
  • Adding/Changing metadata
  • Shorten recordings by omitting frames
