LibVLC.UWP 没有视频 and/or 音频的 UWP?

UWP with LibVLC.UWP no video and/or audio?

我有一个 UWP 应用程序(目标版本 1903 Build 18362),我想在其中嵌入 VLC 视频播放器。这是我的经历:

  1. 正在添加 LibVLCSharp 3.3.1
  2. 正在添加 VideoLAN.LibVLC.UWP 3.2.0

结果:当我捕获事件时,他说他正在缓冲和播放,但没有视频也没有音频。

  1. 恢复到 VideoLAN.LibVLC.UWP 3.1.1.1

结果:当我捕获他说他正在缓冲和播放的事件时,我听到了音频,但没有视频。

我做错了什么?

MainPage.Xaml:

    <Grid>
        <vlc:VideoView x:Name="Video" Width="960" Height="540" />
    </Grid>
</Page>

MainPage.xaml.cs:

using LibVLCSharp.Shared;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace TestVLCinUWP
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            Core.Initialize();

            this.InitializeComponent();

            Loaded += MainPage_Loaded;
        }

        private void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            LibVLC vlc = new LibVLC();
            var media = new Media(vlc, "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4", FromType.FromLocation);
            MediaPlayer player = new MediaPlayer(media);
            Video.MediaPlayer = player;
            player.Play();
        }
    }
}

请看https://github.com/videolan/libvlcsharp/tree/3.x/Samples/LibVLCSharp.UWP.Sample

使用 LVS 3.x /Libvlc 3.x 中的当前设计,您需要在创建 new LibVLC().

时设置交换链选项

至于音频,这是一个已知问题:https://code.videolan.org/videolan/LibVLCSharp/issues/253
