Mediabunny 1.25.0 ships with read/write support for track disposition information! 🚀
This information allows you to inspect which tracks should be preferred by a player, which are meant for hearing- or visually-impaired people, and more.
Niche, but important for some uses.

Probably the funniest error message I've ever seen the browser throw at me.
I apologize for not using 𗜀, 🐀, 𧄀, or 𮸀 as my bitrate

Mediabunny's number of Safari-specific workarounds is growing. Super dirty, but someone's gotta do it!

Had an absolutely terrific two days at Demuxed in London!
Met tons of great people, and I have proudly lost my "conference speaker virginity" now 👀 Excited to share this talk once the VOD drops!
Huge thanks to the Demuxed organizers for letting me have a 20-min slot. 💘

Theo using FFmpeg to build SoraMarker is akin to using create-react-app for a new project in 2025. On the web, it's slow, unnecessarily bulky, and makes very little use of the platform.
I rebuilt it using Mediabunny, and it runs 5x as fast while using 0.8% the bundle size⚡️

Mediabunny v1.24.0 ships with a highly-requested feature: custom video & audio transformations in the Conversion API! 🚀
This means you can now use Mediabunny to add watermarks and overlays, perform color correction, or apply any other video transformation; right in the browser.

Discord should leave tombstones for deleted messages. All other messengers do this already, and I think it's needed when you have deletion, so I'm not sure why Discord hasn't added it.

Open-source project management is quite challenging. I have to balance the roadmap, bug reports, feature requests, etc., and even on my days off, I find myself being dragged into the project because I feel responsible. So for me, this takes conscious effort and improvement.

It's wild how much more clarity you have about your problem when you rewrite your code multiple times. You start seeing patterns that in hindsight seem to obvious, you wonder why you didn't solve it like that the first time around.

Mediabunny v1.21.0 ships with transparency support in the Conversion API, hugely improved error messages if conversions aren't possible (due to missing codec support), and a couple of fixes as usual! 🚀

Mediabunny v1.20.0 is another big milestone for the project: it can now read & write transparent videos! 🚀 All directly in the browser, super fast, no server needed.
This was more challenging that it seems on the surface (took over 1000 LOC). A blog post about this will follow!

Am I wrong for spelling it Mediabunny? Lots of people misspell it as MediaBunny. Mediabunny felt cleaner to me. Might be my inner German speaking!
Won't change the name, just wondering.

Mediabunny v1.19.0 comes with ID3 metadata support in .wav files, better support for alternate environments like React Native, and fancy new Symbol.dispose functionality for Inputs! 🚀
Always cool to work with cutting-edge JS features.

When a new JavaScript feature comes out, I always think, "Who the hell needs that?" Async generators? WeakRef?? FinalizationRegistry??? Symbol.dispose????
And then I always end up finding a use for them a few years later.
What's your favorite "niche" JavaScript feature?

Super excited to announce that I'll be speaking at Demuxed in London this October! 🚀 I'll share Mediabunny's origin story and some of the decisions that shaped its design.
My first real conference talk, so I'm excited. Big thanks for the Demuxed team for giving me a slot! 💘

Neat small blog post I found today, for anybody trying to build code to run both in the browser and in Node. Learned about the "browser" package.json field! It allows you to remap imports if the code is bundled for a browser environment.

I feel like most developers nowadays don't even notice complexity.
I was sent a repro for a Mediabunny bug in the form of a Next.js app. What could've been a 50-line HTML file is instead a 0.5 GB (!!) behemoth.
It's wild to me that this doesn't make people shudder.
