When I included recorder({pipeOutput: true}), ffmpeg was logging “unknown -auto-alt-ref flag”. That flag is added as a vp8 encoding option. Reinstalling ffmeg with libvpx support worked for me:

brew reinstall ffmpeg --with-libvpx --with-libvorbis

That should probably be mentioned in the readme.

Sorry, I’ve been very sick the last week. Getting back to it. I’ll add the information about libvpx to the readme. I’ll be pushing several more updates soon also.

I’m open to accepting pull requests for documentation or code if you have the time and want to make an improvement!
