@michael__ni Hi Michael, great video, I love owls! I don't know how gpac became your default player as it's not intended to be used that way. However I'm concerned that the iphone file would cause troubles. Would you mind sending an issue at https://t.co/x4gGQtkut8 ?

@wokbonds @FawkesFaux @THATS_a_Wolfie @LeagueTruth @WeedLawyerKev Oh for heavens' sake!

This combination of incantations worked.
Various alternatives did not.

Basically do the muxing with MP4Box, but put the PCM file in a mov container first.

Ha ha. I'm asking ChatGPT how to write out a "sidx" atom with AVAssetWriter. Oh, that's easy: just use the mp4box command line tool. Right.

@DaleCurtis @jsconf_india Thank you! 😀
I did come across mp4box.js during my research, but I don't think it supports muxing audio tracks too. Not sure if things have changed.

[Drew Lyton @drewlyton]

I've run into my first brick wall 🧱...finding a well maintained demuxer written in Typescript. This is the spaghetti code I've adapted from the W3C examples using a `.d.ts` shim for MP4Box.js. Would love to know if anyone has any suggestions for alternatives 🙏
