I used up all my Fable credits over the weekend and looks like it’s completely reset as of today.

I now live in Tokyo and still make my Costco runs at least once a month. It's nice to have access to most of the same inventory since moving from Los Angeles.

Launched my suite of media inspection and encoding tools a few months ago, 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.

Seems like if they changed the criteria of downtime. If you hover over the individual days you’ll see lot of degraded messages, but still green.

The abstraction and generic design is part of the point, though. It's not really about writing concrete examples, but experiences and how to be ready to structure based on those experiences.

Wow, GitHub are no longer serious people. Unbelievable.

There were many other options for git and version control in general at the time, though. GitHub made the onboarding to git much easier while using the platform as a social tool.

Very strange take. A lot of software is built on trust and the people behind it. Hence why the social aspect of Github was so important to a lot of open source software.

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.

alfg — Wed, 22 Apr 2026 05:27:15 +0000

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.

It's just capturing inputs and replaying them.

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!
