Hey @ArgoZhang - I've reviewed your changes - here's some feedback:
- Consider separating media device enumeration logic from media stream control logic (open/close/capture) into distinct services.
- Passing DOM selectors from C# services to JavaScript tightly couples the service logic to specific UI implementations.
- Remove the empty
DisplayMediaOptionsandMediaStreamclasses if they are placeholders for future work.
Here's what I looked at during the review

suggestion (bug_risk): Consider handling errors in open() function.
Wrap the navigator.mediaDevices.getUserMedia call in a try-catch to handle permission denials and other errors gracefully.

suggestion (bug_risk): Check for existence of target element in capture().
Ensure document.querySelector('.b-video-image') returns a non-null element before use to avoid runtime errors.
Suggested implementation:
export async function capture(videoSelector) {
const video = document.querySelector(videoSelector);
if (video) {
const bVideoImage = document.querySelector('.b-video-image');
if (!bVideoImage) {
console.error("The element with class 'b-video-image' was not found.");
return;
}If the capture() function uses the bVideoImage element later to display a captured image, ensure that further logic (e.g., drawing from a canvas and setting bVideoImage.src) is placed after this check.

suggestion (bug_risk): Dispose DotNetObjectReference to prevent memory leaks.
Implement IAsyncDisposable (or manually dispose) to release the _interop DotNetObjectReference created in LoadModule when the service is disposed.
Suggested implementation:
class DefaultMediaDevices(IJSRuntime jsRuntime) : IMediaDevices, IAsyncDisposable private DotNetObjectReference<DefaultMediaDevices>? _interop = null; // ... existing code ... private async Task<JSModule> LoadModule()
{
_interop ??= DotNetObjectReference.Create(this); // Other existing methods...
public async ValueTask DisposeAsync()
{
if (_module is not null)
{
await _module.DisposeAsync();
_module = null;
}
if (_interop is not null)
{
_interop.Dispose();
_interop = null;
}
}
