README
# ⚠️ This library is deprecated ⚠️
mp4-muxer has been deprecated in favor of [Mediabunny](https://github.com/Vanilagy/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](https://github.com/Vanilagy/mediabunny) has got you covered. Refer to the following documents to jump right in:
- [Guide: Writing media files](https://mediabunny.dev/guide/writing-media-files)
- [Quick start: Create new media files](https://mediabunny.dev/guide/quick-start#create-new-media-files)
## My code already uses mp4-muxer. What should I do?
No worries. You can easily [migrate to Mediabunny](./MIGRATION-GUIDE.md) in 10 minutes.
If you still need the docs for mp4-muxer, you can find them [here](https://github.com/Vanilagy/mp4-muxer/blob/2c611c5932d3b8054c8968320cf9b6b7db094d30/README.md).
