Have output video appear as normal video file #19

I understand this might be on purpose to allow easier streaming on websites but I'm not using it for a website and there aren't really any other good alternatives. Is there any way to either convert the file or toggle on/off so it won't be endless?

Anyways I love the project it works great for what it is supposed to do.

This is because the MediaRecorder of chrome only is able to record webm video. You need to convert it with ffmpeg. See #14 and #9

Hi, just another question. I got it to work with your ffmpeg example. But is there anyway to encode it with ffmpeg after it is done recording?

SamuelScheit commented 2 years ago

have a look at the documentation of ffmpeg, you can do all sort of re-encoding and video/audio editing: https://www.ffmpeg.org/

One last thing. ffmpeg is absolutely tanking my cpu. I tried adding '-threads 1' but it hasn't made a dent. Know of any ways to minimize cpu usage?

const ffmpeg = exec(`ffmpeg -y -threads 1 -i - ./videos/${filename}-export.mp4`);

Update: I fixed the issue by limiting fps using -r
