nwjs-ffmpeg-prebuilt VS ffmpeg.wasm

You need libffmpeg. You can download a prebuilt one from here. Put libffmpeg.so file to lib_extra directory at Opera's installation directory (probably /usr/lib64/opera).

Hi HN! I'm Ivan, the creator of this extension and with it you can now right-click any gif on Google Chrome (desktop) to share it with any of your contacts on WhatsApp Web, you can also use it to upload animated GIFs from your computer, you can even drag-and-drop MP4 files to it and they will be treated as gifs (e.g. they will loop, muted of course). Another nice feature its that it lets you share non-gif images with the same context menu option (e.g. AKA right-click menu)

To create it I had to do a bit of reverse-engineering of the existing JavaScript found at https://web.whatsapp.com/, which is actually a minified React app, I found out that it uses WebSockets to communicate with the backend but thankfully to create this extension I was able to avoid fiddling with those messages. Under the hood it uses the amazing library ffmpeg.wasm (the JS port of ffmpeg): https://github.com/ffmpegwasm/ffmpeg.wasm I also made use of TypeScript, React and Vite to create this extension, using this boilerplate as starting point: https://github.com/Jonghakseo/chrome-extension-boilerplate-r...

Feel free to ask any questions or any feedback you may have about it.

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.
