在Xamarin UWP中创建软件包后，视频只能通过语音播放，我看不到视频 [英] After Creating Package in Xamarin UWP, Video is Playing Only With Voice, I am Not able to see Video

问题描述

我正在使用最新版本的MediaManager插件来播放视频.当我在调试模式下运行应用程序时，一切正常，但是当我为窗口创建一个程序包时，视频显示的不是声音，而是声音.

I am using MediaManager Plugin with latest version to play a video. everything works fine when i run application in debug mode, but when i create a package for window, video is not showing only voice is heard.

我正在使用以下Package

I am using below Package

Plugin.MediaManager.Forms

这是我的XAML页面

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="Digi_Sign.Views.MediaScreen"
             xmlns:forms="clr-namespace:MediaManager.Forms;assembly=MediaManager.Forms"
             BackgroundColor="Black">
    <ContentPage.Content>
        <Grid x:Name="stkLayout" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand" BackgroundColor="Black">
            <forms:VideoView VideoAspect="AspectFill"  x:Name="videoPlayer" ShowControls="False"  />
             </Grid>
    </ContentPage.Content>
</ContentPage>

CS页面

CrossMediaManager.Current.Play(fileName);

在包错误日志中未找到错误，因为我提到在调试模式下一切正常，但在发布模式下不工作

No Errors Found in package error log, as i mentioned everything works fine when it is debug mode, but not working in release mode

推荐答案

基本上，无法使用xamrin.UWP的本机代码初始化视频的渲染器，因此我们需要在初始化时手动加载渲染程序集UWP平台的App.xaml.cs

下面是我的代码，其中我在 OnLaunched()中加载了程序集文件，并替换了现有的 Xamarin.Forms.Forms.Init()

Below is my code where i have load assembly files inside OnLaunched() and replace existing Xamarin.Forms.Forms.Init()

  protected override void OnLaunched(LaunchActivatedEventArgs e)
        {
            Windows.UI.Xaml.Controls.Frame rootFrame = Window.Current.Content as Windows.UI.Xaml.Controls.Frame;
            if (rootFrame == null)
            {

                rootFrame = new Windows.UI.Xaml.Controls.Frame();
                rootFrame.NavigationFailed += OnNavigationFailed;

                List<Assembly> assembliesToAdd = new List<Assembly>();
                assembliesToAdd.Add(typeof(VideoViewRenderer).GetTypeInfo().Assembly);
                Xamarin.Forms.Forms.Init(e, assembliesToAdd);


                // Place the frame in the current Window
                Window.Current.Content = rootFrame;
            }

            if (rootFrame.Content == null)
            {
                rootFrame.Navigate(typeof(MainPage), e.Arguments);
            }

            Window.Current.Activate();
        }
