mp4-muxer

This library is deprecated

mp4-muxer has been deprecated in favor of Mediabunny, which entirely supersedes it. Mediabunny ships with an even better, easier-to-use, faster and more feature-rich MP4 multiplexer, as well as muxers for many other formats, demuxers, WebCodecs abstractions and more, while keeping the bundle size tiny thanks to a tree-shakable design.

mp4-muxer is no longer being maintained and will not receive any new features or bug fixes.

I just want to create an MP4 file.

Mediabunny has got you covered. Refer to the following documents to jump right in:

• Guide: Writing media files
• Quick start: Create new media files

My code already uses mp4-muxer. What should I do?

No worries. You can easily migrate to Mediabunny in 10 minutes.

If you still need the docs for mp4-muxer, you can find them here.
