Consider handling the case where mediaStream is not initialized due to granted being false.
Currently, if granted is false, mediaStream remains null, and the subsequent code attempts to set videoRef.current.srcObject to null, which is not handled. This could lead to unexpected behavior or errors in the video playback logic.

Add a check to ensure videoRef.current is not null before proceeding with initialization.
The check if (!videoRef?.current) return uses optional chaining which will not throw but simply return undefined if videoRef is null. It's safer to explicitly check for null to avoid any potential issues with undefined behavior.

Consider moving the init function call inside the useEffect dependency array.
By moving the init function definition inside the useEffect hook, you can ensure that it has the most up-to-date closures over its dependencies, which is crucial for functions that depend on external state.

Refactor the cleanup function to handle potential null values more gracefully.
- if (stream) {
- stream.getTracks().forEach((track) => track.stop())
- }
+ stream?.getTracks().forEach((track) => track.stop())This change uses optional chaining to make the code more robust and concise, ensuring that it handles cases where stream might be null.

14-22: The implementation ofgrantCamerafunction looks good. It properly handles the asynchronous request for user media and updates the state based on the outcome.
43-47: The dependencies of theuseMemohook are correctly set to include all relevant state setters and values. This ensures that the context value is recalculated only when necessary.

Ensure to handle the promise returned by videoRef.current.play(). This method returns a promise that could reject if the play request is interrupted by a new load request or if the user didn't interact with the document before.
