A Java library for reading, writing, and creating MP4 container files. It manipulates the container structure (muxing, appending, metadata, frame trimming) rather than encoding or decoding audio/video streams.
Use cases
- mux raw h264 and aac streams into an mp4 file
- append multiple video recordings with the same encode settings
- edit or add metadata to mp4 files
- shorten a recording by dropping frames without re-encoding
- parse mp4 container structure in a java application
When to choose
- you need to manipulate MP4 container structure from Java or any JVM language
- you want to mux or concatenate tracks without re-encoding video
- you need to read or modify MP4 metadata programmatically
When to avoid
- you need to encode or decode video/audio codecs themselves
- you are not working on the JVM and need a native solution
- you need broad format support beyond MP4/ISOBMFF containers
