Video and audio mixer with audio recording capabil

问题:

How can I make a video and audio mixer with audio recording capability using nodejs. Also I want an editable waveform graph of audio. Is there any supporting package in nodejs?

Unless you are lucky enough to find a package that does exactly what you want, I suspect that using ffmpeg through a nodes wrapper of interface library such as the one below will be the easiest approach:

This allows you use all the power and large user community behind the ffmpeg command line program, but wrapped in a node.js friendly interface.
