dynamically change canvas size for render?

[munge]

when trying to pass width and height dynamically, says rendering stops in runtime with conversion failed status:
'error Error: ffmpeg exited with code 1: Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!'

here is my code:
.....
const VideoEncoder = async (res, canvasJSON, cWidth, cHeight) => {

try {
    const stream = await renderer({
        silent: false,
        width: cWidth,
        height: cHeight,
        fps: 30,
        makeScene: (fabric, canvas, anim, compose) => {

......

when width and height is number, not variable works fine

I tried to reproduce your issue but I couldn't. Can you please check your code to make sure width and height variables are non-zero numbers? If so, please provide a code or a repository with minimal reproduction.
