ffmpeg.wasm

For anyone interested in trying FFmpeg in the browser: https://github.com/ffmpegwasm/ffmpeg.wasm No affiliation -- found it while searching for browser-based ports of FFmpeg.

It would be even cooler to get it working in user browser with local CPU and no upload thanks to ffmpeg on WASM: https://github.com/ffmpegwasm/ffmpeg.wasm

In fact, the header must be set in the server-side, which means I cannot do that as I am using github pages. You can check more details here: https://github.com/ffmpegwasm/ffmpeg.wasm/issues/102

You can use this in Safari https://github.com/ai/audio-recorder-polyfill https://github.com/GoogleChromeLabs/webm-wasm Safari doesn't play webm files two options for that 1). you can convert webm to MP4 with or without re-encoding(will be faster) using ffmpeg or ffmpeg-wasm (within browser) https://github.com/ffmpegwasm/ffmpeg.wasm 2). Another option is play webm directly using wasm https://github.com/brion/ogv.js

This is pretty cool. I've also been playing around in this area lately and noticed there's still a drastic performance hit. But seems to work great for smaller files. Question: Are you compiling FFmpeg to WASM, or FFMpeg's libav and interfacing with that directly? Also for anyone curious, the author of ffmpeg.wasm[1] has an excellent guide on compiling FFmpeg to WASM: https://itnext.io/build-ffmpeg-webassembly-version-ffmpeg-js...

Hello HN Modfy is a purely browser-based privacy-first video tool capable of performing tasks like converting, compression, etc without uploading your files. I thought it would be cool to process video in the browser using Web Assembly and FFmpeg The project is also open source and based on https://github.com/ffmpegwasm/ffmpeg.wasm Let me know what you think!
