@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 github.com/gpac/gpac/issu… ?

Was trying to mail a mp4 to a someone and realized ubuntus default player (gpac) for video/mp4 is not capable to play an mp4 from an iphone upright. Just use ffplay, put something like this in /etc/mailcap

💪 Thanks Dimitri Podborski and Deniz Ugur for the hard work and the GPAC heads up 😎 while presenting your work on #MPEG File Format #Conformance at the #OSMART workshop. Someone's tacking the challenge of increasing standard complexity 👏 github.com/MPEGGroup/File…

@ldenoue @HCornflower In quality mode you'll want to feed it frames until you get output. You only need to call flush at the end. I'm not sure why mp4box doesn't like that codec string. It seems valid, but I'll double check on Monday.

Some strange webcodec bug: if you specify prefer-software in hardwareAcceleration then you need to call flush after every frame you encode or it just stops there hanging….

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.

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 🙏

Now that Safari/HLS has secret support for VP9 in ISOBMFF, I can revive hope for Opus in ISOBMFF support, too.
