ffmpeg.wasm VS WASM-ImageMagick

There's already ffmpeg wasm. I've used it in projects. Works great.

There's a low-hanging fruit that I think would make ffmpeg more helpful for regular people.

There's a million terrible websites that offer file conversion services. They're ad-ridden, with god-knows-what privacy/security postures. There's little reason for users to need to upload their files to a third-party when they can do it locally. But getting them to download fiddly technical software is tough - and they're right to mistrust it.

So, there's a WASM version of ffmpeg, already working and hosted at Netlify [1]. It downloads the WASM bundle to your browser and you can run conversions/transformations as you wish, in your browser. Sandboxed and pretty performant too!

If this tool a) was updated regularly b) had a nicer, non-CLI UI for everyday users and c) was available at an easily-Googlable domain name - it would solve all the problems I mentioned above.

As their github page says, based on https://ffmpegwasm.netlify.app ...

I'm guessing no one did GPU-optimizations? I saw a web app (not an ffmpeg transpilation) that went clever and used WebGL so it can access the GPU and use its parallel processing capabilities...

ffmpeg.wasm: The engine making all these happen. However, I’m a bit concerned about its current situation. The repo has not been updated for more than six months now, and that’s not a healthy sign for an open-source project. Clearly I was reading the commits wrong. The author mentioned “speed up x264 with SIMD intrinsics” in their roadmap (https://github.com/ffmpegwasm/ffmpeg.wasm/discussions/415), which, if landed, could make such on-device video editors much more competitive.

I use https://github.com/ffmpegwasm/ffmpeg.wasm and I want my FFMPEG commands to be hidden from others.

Possibly using this? https://github.com/ffmpegwasm/ffmpeg.wasm

You could try using something like ffmpeg wasm which is a way of using ffmpeg client side in browser. Unfortunately WebAssembly only supports files less than 2 gigabytes, which is a problem for videos. And I don't know if ffmpeg wasm contains ffprobe, so you might have to find another project or try to compile ffprobe to wasm yourself. This stuff is out of my wheelhouse so I can't offer much help.

Image Conversion via WASM-ImageMagick

I've gone with ImageMagick ported to WebAssembly to do basically the exact same things as with FFMpeg, but with a tiny bit less locking up. In the future I would like to get these things running in multithreaded Web Workers as well as have the ability to easily configure transcode settings to whatever is desired instead of the defaults as it is now.

When it comes to audio/video the trusted tool that is often used on the desktop is FFmpeg and this too has been ported to run in the browser, although if you want multithreading you will need to make sure you have special CORS headers enabled to gain access to the SharedArrayBuffer. For images on desktop there is the popular ImageMagick which indeed also has been ported.

ImageMagick is the go to for these kinda things and apparently there is a WASM version: https://github.com/KnicKnic/WASM-ImageMagick
