Research direction

This is a years-old feature request asking whether MP4Box's CLI -add (muxing an mp3 audio track into an mp4) and -cat (concatenating mp4 files) will be ported to mp4box.js; the single comment thread never produced a decision, and no pull request is linked. Nothing in the payload names a file, API or test, so the first step would be reading the repository's existing muxing and segmentation APIs to judge feasibility. Done here would mean a maintainer-approved design proposal scoped into separate issues, not a newcomer patch.

Description

enhancement

Hi there, I'm looking for a library to mux mp3 audio into an mp4 container using javascript, as well as concatenate multiple mp4 files. Are there any plans to port those features to mp4box.js?

Thank you
