In plain words
FFmpeg WebCLI is a browser-based video and audio editor that runs entirely on your device using WebAssembly, with no files uploaded to servers. All processing happens locally in a Web Worker, keeping your media private. The tool works offline as a progressive web app once initially loaded and can be installed on your device for easy access. It provides full FFmpeg functionality directly in the browser without requiring software installation.

VidStudio, a browser based video editor that doesn't upload your filesApr 2026 · vidstudio.app · ▲301Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it.

FFmpeg-over-IP – Connect to remote FFmpeg servers2024 · github.com · ▲147Dear HN, I’m excited to show case a personal project. It has helped me quite a bit with my home lab, I hope it can help you with yours too! ffmpeg-over-ip has two components, a server and a client. You can run the server in an environment with access to a GPU and a locally installed version of ffmpeg, the client only needs network access to the server and no GPU or ffmpeg locally. Both and client and the server need a shared filesystem for this to work (so the server can write output to it, and client can read from it). In my usecase, smb works well if your (GPU) server is a windows machine,…

CompressX, my FFmpeg wrapper for macOS2024 · compressx.app · ▲170Hey HN, just wanted to share my success story with CompressX, my FFmpeg wrapper for macOS. For those who may not be familiar, FFmpeg is a powerful tool for converting, streaming, and recording audio and video content. I started CompressX as a weekend project to serve my 9-5 jobs, primarily to compress demo videos for uploading to GitLab and sharing with my colleagues. It took me 2 weeks to make the first working version. I shared the demo on Twitter and the reaction was extraordinary. People loved it, they said that I was bringing the Pied Piper to life. Four months later, I hit the $9,000…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate).

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
