如何拦截错误并更改 libvlcsharp xamarin 表单的样式 [英] How to Intercept errors and change the style of libvlcsharp xamarin forms

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>
