Xamarin.Forms MediaManager 从本地存储播放视频

Question

I am creating custom cross-platform video player with MediaManager. It plays video from https but I want it play video from local storage.

        var folder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
        folder = Path.Combine(folder, "UserVideos/testvideo.mp4");
        videoPlayer.Source = folder;
        CrossMediaManager.Current.Play("file://" + "/UserVideos/testvideo.mp4");

I tried this way, but it doesn't play video. Folder UserVideos is in main namespace.

Would you confirm whether the file testvideo.mp4 is stored in internal storage or external storage? From your code, I guess that you want to get video from internal storage, but files in internal storage that cannot be shared, and you don't see it.

https://docs.microsoft.com/en-us/xamarin/android/platform/files/#internal-vs-external-storage

So when using a file:// based URL, I suggest you can copy your video in Assets folder and BuildAction is AndroidAsset .

Then play video like this:

CrossMediaManager.Current.Play("file:///android_asset/minions.mp4");

I install Plugin.MediaManager.Forms by Nuget package, then init in Mainactivity.cs:

CrossMediaManager.Current.Init(this);

MainPage.xaml:

 <StackLayout>
        <video:VideoView HeightRequest="300" WidthRequest="200" />

        <Button Text="play local video" Clicked="BtnPlayLocal_Clicked"/>
    </StackLayout>



 private void BtnPlayLocal_Clicked(object sender, EventArgs e)
    {           
        CrossMediaManager.Current.Play("file:///android_asset/minions.mp4");
    }

Update

If you want to play video in Xamarin.ios, please add video in Resource folder and BuildAction is BundleResource

Then Play video like this:

CrossMediaManager.Current.PlayFromResource("minions.mp4");

Full code:

private  void BtnPlayLocal_Clicked(object sender, EventArgs e)
    {
        if (Device.RuntimePlatform == Device.iOS)
        {
            CrossMediaManager.Current.PlayFromResource("minions.mp4");
        }
        else if (Device.RuntimePlatform == Device.Android)
        {
            CrossMediaManager.Current.Play("file:///android_asset/minions.mp4");
        }

    }
