Error installing and using in our App

Hi,

When I try the gif format, I get an error:

1. After cature.save(), I get below error:

Uncaught Error: Width and height must be set prior to rendering

When trying webWriter, I get the below errors/issues

1. After capture.start(), I use a setTimeout for 3 seconds before capture.stop() and capture.save(). The setTimeout never gets fired because of the internal clearTimeout in capture.start()

2. Even when I try to stop recording using a button onClick, I get following error when I capture.save()

WebMWriter.js:230 Uncaught TypeError: Cannot read property 'dataOffset' of undefined
    at fileOffsetToSegmentRelative (WebMWriter.js:230)
    at writeCues (WebMWriter.js:500)
    at Object.complete (WebMWriter.js:642)
    at CCWebMEncoder.webpackJsonp.2150.CCWebMEncoder.save (CCapture.js:2

This is caused by the below lines

            function fileOffsetToSegmentRelative(fileOffset) {
                return fileOffset - ebmlSegment.dataOffset;
            }

PS: I am using webm-writer NPM package import WebMWriter from "webm-writer";

Actually, I just decided to write a canvas recorder of my own using MediaSource/MediaRecorder. Found some open source code and made some slight modifications.

This is my CanvasRecorder.js file: https://pastebin.com/raw/U7kwaV5S

…which produced this kind of thing in conjunction with some canvas drawing stuff: https://presentio.us/view/18b3ba

Unfortunately MediaSource/MediaRecorder support for the iPad is non-existent, so I’m back to the drawing board looking at ffmpegserver.js
