Description

So far If I want record video+audio, it seem need use the RecordRTC?
If use other plugin such as "webm-wasm" it seem will only record video without sound.
So I want to try use some converter, such as ffmpeg.js with RecordRTC?
But seem not luck with many config I try.
Do you mind provide a example for convert to mp4 (Video+Audio) with common codec such as h264?

Steps to reproduce

Some config I test

			convertOptions: ['-f', 'mp4', '-codec:a', 'aac', '-codec:v', 'libx264'],
			pluginLibraryOptions: {
				outputType: 'video/mpeg'
			},

Results

Expected

Convert success

Actual

Throw exception

Error output

uncaught exception: [object Object]
ffmpeg-worker-mp4.js:17:59
