I love my Brompton. I've had mine for 12 years that I bought back in LA and brought it with me when I moved to Tokyo. It's such a great commuter for getting around the city and easily fits in my trunk when I want to take it with me for a trip.

Tokyo also has a couple of great Brompton shops for maintenance and parts.

Wow, and I already prepaid for the year. Figures.

This is how I handle it with my latest project, https://video-commander.com.

Prompting the user to install, or auto-installing FFmpeg separately, rather than bundling the binary. The problem is FFmpeg can be configured in so many ways and the general install binaries are usually LGPL compatible.

Looks good. Good work on shipping! I love seeing video applications utilizing Web Assembly. However, it usually falls short in when it comes to longer video in the browser's sandboxed environment.

How is the performance? Curious if you've tried using the FFmpeg libraries directly (libav), rather than compiling all of FFMpeg to WASM?

I always end up using running FFmpeg directly since it's faster and more reliable, but I still have some hope for a full functioning browser-based implementation someday.

I also made https://ffmpeg-commander.com a while back to generate commands for FFmpeg.

I live in Tokyo in a 2 story house. Felt it swaying quite a bit for a few minutes.

It's just capturing inputs and replaying them.

Just recently launched my suite of media inspection and encoding tools based on FFmpeg.

https://video-commander.com.

Still iterating through refinement and features. It's built on Rust + Tauri with a React frontend, in case anyone is curious.

I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium.

Show HN: Video Commander – A desktop IDE for video engineers (FFmpeg, VMAF)

alfg — Tue, 07 Apr 2026 15:33:19 +0000

I've been building open-source tools in the video/multimedia space for 10+ years. Finally shipped the commercial product I always wanted to exist — Video Commander, a desktop app that consolidates FFmpeg, ffprobe, MediaInfo, VMAF and more into a single workspace where you can inspect, encode and analyze video.

Built with Tauri + Rust backend, React frontend. FFmpeg and VMAF.

Not a cool AI/LLM project, just a tool I've been heads-down building over the last six months.

Happy to answer any questions!

Prior to LLMs, I made an ffmpeg command line builder. It definitely doesn't cover everything, but handles simple common tasks quite well.

Building ffmpeg can be simple or complex, depending on how you configure the dependencies and if it's dynamic or static and of course it's target outputs.

I'm currently working on a cross-platform builder that runs within Github Actions runners, but the Mac and Windows builds take up so many of my monthly minutes.

https://github.com/video-commander/ffmpeg-builder

I'm using this as part of another multimedia app I'm working on for video engineers.

alfg — Wed, 11 Mar 2026 00:55:57 +0000

This is pretty neat. I was experimenting something similar with my ffmpeg frontend to connect to the local machine (and remote) to run arbitrary encoding jobs, thus offloading the encode tasks to another machine, but still with a queuing mechanism locally.

The project is https://ffmpeg-commander.com for generating ffmpeg commands, but with an experimental backend to offload the tasks.

Do you support chunked encoding across multiple servers? It would be a great feature to support larger video files.

In Japan many people call it "Chappie" (チャッピー), which I think is much easier to say and less awkward, haha. I see a lot of people using it here daily.

I feel like OpenAI should lean into that.

I'm sure there's plenty of overlap with just using a CONTRIBUTING.md or even the README.md development setup. Especially since LLMs should understand guidance in human instructions.

In case anyone is looking for a FFmpeg command builder that's not ai-generated:

https://github.com/alfg/ffmpeg-commander

Haven't updated in a while, but it's a simplified web UI with a few example presets.
