WebCodecs-based API for reading audio data partially

[nicolascoutureau]

Bug Report 🐛

Hey,
I have a "page crashed" error when trying render a video with useAudioData and visualizeAudio.
It seems to happen when the mp3 duration is long (~1 hour).

I have 4Gb of Ram and 10Gb of space on the lambda.

Here is an example file: https://cdn.revid.ai/uploads/1745193542633-audio.mp3

Any idea how I can fix this?

At the moment, we have useWindowedAudioData(), but it only works for .wave files: https://www.remotion.dev/docs/use-windowed-audio-data

This is the best for you right now.
We are working on a better, WebCodecs-based solution that can also read MP3 files partially, I'll take the opportunity to turn this issue into that feature request

Here is a prototype if you would like to play with it!
