This is my h5 code:

<video id="myVideo" src="xxxapp://***.***.xx/***/***.mp4" style="object-fit:cover;opacity:1;width:100%;height:100%;display:block;possition:absolute;" type="video/mp4"></video>

I want to load local large video, so, I use WKURLSchemeHandler.

- (void)webView:(WKWebView *)webView startURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask {
    NSURLRequest *request = [urlSchemeTask request];
    NSURL *url = request.URL;
    NSString *urlString = url.absoluteString;
    NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"***" ofType:@"mp4"];
    NSData *videoData = [NSData dataWithContentsOfFile:videoPath options:nil error:nil];
    NSURLResponse *response = [[NSURLResponse alloc] initWithURL:url MIMEType:@"video/mp4" expectedContentLength:videoData.length textEncodingName:nil];
    [urlSchemeTask didReceiveResponse:response];
    [urlSchemeTask didReceiveData:videoData];
    [urlSchemeTask didFinish];
}

but its not work, data is not nil, but video do not play. I would greatly appreciate it if someone could help me find a solution!!

ps: <video><source/></video> can make it, but we cannot use it due to some reasons.
