Implementing mp4

[ffd8]

Really excited for this and your example here does an amazing job of exporting an mp4 too (the main element missing from most canvas recording techniques, as not too many platforms/apps support webm).

Is the ffmpeg.min.js from the example your own reduction for this conversion or from somewhere else? Was trying to find a simple way to convert webm's to mp4 in browser or blobs straight to mp4 and couldn't find anything nearly so small... only 10+ mb libs.

Can't wait for mp4 to be part of this library and hope you'll include some sort of options in the method for which/multiple formats to save on export (like in example above).
