record
(frameRate?: number, mimeTypes?: string[]): RecordingStart recording the canvas into a video.
Note: This relies on the browser's support using the MediaRecorder
API, and support is buggy at best from my (@dragoncoder047)'s testing.
The best results I have gotten are with explicitly specifying video/webm
and 60 FPS.
Results with the default values are usually no good and even if both MIME
type and framerate are specified, dropped frames, truncated videos,
audio desynchronization, and even completely corrupted files have been gotten
from this. video/mp4 is technically supported by some browsers but I can't
recommend it as MP4 has produced glitched and/or corrupted files much more often
than WebM in my testing.
If your players want to get a nice clean recording it's probably a better
idea to point them to an external screen-recording program such as
[OBS](https://obsproject.com).
param frameRate- Target frame rate for the output video.
If framerate is not specified, a new frame will be captured each
time the canvas changes.
param mimeTypes- A list of MIME types such as `video/mp4`, `video/webm`.
The browser will select the first one it can do when the recording is started.
If none are supported, an error will be thrown.
