HTMLVideoElement missing requestVideoFrameCallback

[jameshfisher]

Possibly the spec is too early for inclusion. For others with the same issue, here are the types I came up with:

interface VideoFrameMetadata {
    presentationTime: DOMHighResTimeStamp;
    expectedDisplayTime: DOMHighResTimeStamp;
    width: number;
    height: number;
    mediaTime: number;
    presentedFrames: number;
    processingDuration?: number;
    captureTime?: DOMHighResTimeStamp;
    receiveTime?: DOMHighResTimeStamp;
    rtpTimestamp?: number;
};
type VideoFrameRequestCallbackId = number;
interface HTMLVideoElement extends HTMLMediaElement {
    requestVideoFrameCallback(callback: (now: DOMHighResTimeStamp, metadata: VideoFrameMetadata) => any): VideoFrameRequestCallbackId;
    cancelVideoFrameCallback(handle: VideoFrameRequestCallbackId): void;
}

I'm kinda new to this, would there be a way for me to override the interface in my own type definition file for the time being?

@PindaPixel you should just be able to copy-paste the above definitions in your own file - possibly wrapping it all in declare global { ... }

Hello @jameshfisher :)
After 5 years of your issue being open, I’m happy to share that it is now officially supported in TypeScript as of 2024! It’s been added to the latest version.
