Using a ReadStream as input

[Grasscropper]

Is your feature request related to a problem? Please describe. I want to be able to cut clips from one or more large videos and concat them (something like a highlight video). To do so I have to copy the whole video to FS and then run ffmpeg on it. I've implemented a version of this nodejs (not a wasm version) and wanted to move towards client side editing. There you could create a readstream and use that as input for ffmpeg. Unfortunately it seems this is not possible in ffmpeg wasm (unless I'm missing something).

Describe the solution you'd like I'd like some way to use a readstream as input for ffmpeg.

Describe alternatives you've considered I'd have to go back to my old implementation or accept load 2Gb+ into memory.

I would like to stream input as well. I have very large video files on a backend that I'd like to stream to ffmpeg on the client. Loading the entire video isn't feasible.

Same here. I have large video files (>2gb) that I need to extract the audio as mp3. Using files beyond 2gb keeps the browser crashing, so streams would be the only option I guess.

Any news on this?
