Nice interface at a first glance, for sure can be useful for users who would find using the actual thing too cumbersome. How does performance compare to the native app? Is any form of hardware decoding/encoding like h264_nvenc available? (I guess not?)
Note those only apply to scene_sad which is used for scene change detection and freeze detection and a few other things like mpdecimate -- it's a very specific use case
vibe-coded, and the github repo does not even contain the sources, just a single 'server.js' that is only for the documentation
this is ffmpeg running inside the browser am I correct? did not know this was possible. wonder what else we can run via webassembly
Just a thought - is the text “Click to upload” with a cloud icon perhaps a bit misleading?
If it’s fully client side, then you are just opening a file in essence - no clouds in sight!
I agree something like a folder or file icon would be more accurate.

I would imagine the only way to use NVENC directly from a browser would be via WebCodecs.
This is dope. Made a PR.
Any chance those AVX-512 optimizations they released a while ago work within this? [1]

I think WASM SIMD is only 128-bit wide.
