Unable to combine video and audio

[martinnaj]

I downloaded the demo and all files associated with it, and added my own: input.mp4, input.mp3

I tried the following:

ffmpeg.exe -i input.mp3 -i input.webm -acodec copy -vcodec copy muxed.mp4

and got the error:

input.mp3: No such file or directory

it seems that NO AUDIO FORMAT IS RECOGNISED

It works with ffmpeg in cmd, so fix it here please

Use ffmpeg.wasm. This is fast and supports browsers, but it takes a huge amount of memory.
