问题描述

我已在我的 Xamarin.Forms 项目中正确实施了 LibVlcSharp.

I have correctly implemented LibVlcSharp in my Xamarin.Forms project.

using (var _libVLC = new LibVLC())
            {
                var media = new Media(_libVLC, _link, FromType.FromLocation);
                myvideo.MediaPlayer = new MediaPlayer(media)
                {
                    Fullscreen = true
                };
                myvideo.MediaPlayer.Play();
            };

在我的视频播放器中，我从谷歌驱动器流式传输视频，但有时可能会发生媒体出错并显示此错误:

In my video player I stream video from google drive but sometimes it can happen that the media gives error and this error is shown:

流媒体工作，错误的原因可能有很多，但这不是我感兴趣的.我想了解如何拦截此错误和自定义此错误标签，但我在文档或在线中未找到任何内容.

Streaming works, there may be many reasons for the error but that's not what interests me.I would like to understand how to intercept this error and customize this error label but I have not found anything in the documentation or online.

我还想知道是否可以更改按钮的样式，我发现此属性 myvideo.PlaybackControls 具有许多其他属性，但我不知道它是否正确以及如何应用它.

I also wanted to know if it was possible to change the style of the buttons, I found this property myvideo.PlaybackControls that has many other properties but I do not know if it is correct and how to apply it.

谢谢

推荐答案

看看

 <Label Text="{TemplateBinding ErrorMessage}" Style="{TemplateBinding MessageStyle}"
                       IsVisible="{TemplateBinding ErrorMessage, Converter={StaticResource ObjectToBoolConverter}}" />

来自 https://code.videolan.org/videolan/LibVLCSharp/-/blob/3.x/LibVLCSharp.Forms/Shared/Themes/Generic.xaml.这是您要修改的 LibVLCSharp 提供的基本样式.

From https://code.videolan.org/videolan/LibVLCSharp/-/blob/3.x/LibVLCSharp.Forms/Shared/Themes/Generic.xaml. This is the base style provided by LibVLCSharp that you want to modify.

您可以按照本指南覆盖样式 https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/styles/xaml/inheritance

You can override the style by following this guide https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/styles/xaml/inheritance

在 XAML 中，这可能是

In XAML, that could be

<Style x:Key="labelStyle" TargetType="Label" BasedOn="{StaticResource MessageStyle}">
   <Setter Property="TextColor" Value="Teal" />
</Style>
