不过，您在尝试使用Chromecast加密狗进行流式传输时可能会遇到一些问题，例如“不支持源”错误。 

以下是为什么会发生此错误以及如何修复它。

Google Chromecast“不支持来源”错误的原因^{(Causes of the Google Chromecast “Source Not Supported” Error)}

您可能会看到Chromecast“^{(Chromecast “)}不支持源”错误的原因有多种，包括： 

• 您用于流式传输内容的应用程序中偶尔出现错误。
• 互联网连接不良或低带宽^{(Poor or low-bandwidth internet connection)}。请参阅我们的指南，了解如何在没有 Wi-Fi 的情况下使用 Chromecast。^{(how to use Chromecast without Wi-Fi.)}
• 您的移动设备、路由器或Wi-Fi网络设置存在问题。

让我们看看一些故障排除提示和修复方法，您可以使用它们来解决此错误并再次开始通过Chromecast将内容投射到您的电视上。

快速修复^{(Quick Fixes)}

• 重新启动路由器、笔记本电脑或手机以及Chromecast设备以刷新连接。
• 重新启动^(Restart)或更新您尝试从中流式传输内容的应用程序，然后再次尝试投射。

•  检查您的电视和用于投射的设备是否在同一个Wi-Fi网络上。 
• 右键单击要投射的笔记本电脑^{(laptop you’re casting from)}上的视频，选择投射到设备，^{(Cast to Device,)}然后从列表中选择您的Chromecast设备，看看它是否有帮助。
• 禁用任何可能在您的手机或计算机后台运行的代理服务，例如VPN 。

禁用实时保护^{(Disable Real-Time Protection)}

如果您已尝试过快速修复，但均未奏效，请尝试暂时禁用Windows Defender^{(Windows Defender)}上的实时保护功能并检查是否可以再次投射。实时保护功能会扫描您在设备上运行的下载和程序，因此请确保重新打开它以保护您的设备免受病毒或恶意软件的威胁^{(keep your device safe from the threat of viruses or malware)}。

1. 打开Windows Defender 安全中心^{(Windows Defender Security Center)}并选择病毒和威胁防护^{(Virus & threat protection)}。

1. 选择病毒和威胁防护^{(Virus and threat protection)}设置并禁用实时防护^{(Real-time protection)}切换开关。

尝试再次通过Chromecast投射您的内容，以查看实时保护功能是否导致问题。如果没有，请再次启用实时保护并尝试下一个解决方案。

启用加载媒体路由器组件扩展^{(Enable the Load Media Router Component Extension)}

媒体路由器组件^{(Media Router Component)}扩展用于将您的浏览器投射到支持Chromecast的电视或Chromecast设备。默认情况下应禁用该扩展程序，但您可以启用它并查看它是否修复了Chromecast “不支持源”错误。

1. 打开 Chrome 并在地址栏中输入chrome://flags/#media-router。

1. 接下来，搜索Router Component。

1. 将设置从默认更改为启用^(enabled)。

How to Fix a Chromecast “Source Not Supported” Error

If you want to convert an ordinary TV into a smart TV, Google Chromecast offers a quick and easy way to stream media to your TV wirеlessly. You can cast content over Wi-Fi to your TV from your phone or your laptop. There are many other cool things you can do with Chromecast.

Still, you may encounter a few issues when trying to stream with your Chromecast dongle, such as the “Source not supported” error. 

Here’s a look at why this error occurs and how you can fix it.

Causes of the Google Chromecast “Source Not Supported” Error

There are several reasons why you may see the Chromecast “source not supported” error, including: 

• An occasional bug in the app you’re using to stream content.
• Poor or low-bandwidth internet connection. See our guide on how to use Chromecast without Wi-Fi.
• Issues with your mobile device, router, or Wi-Fi network settings.

Let’s look at some troubleshooting tips and fixes you can use to resolve this error and start casting content to your TV via Chromecast again.

Quick Fixes

• Restart your router, laptop, or phone, and the Chromecast device to refresh the connection.
• Restart or update the app you’re trying to stream content from and then try to cast again.
• Make sure the app you’re streaming from and the Chromecast device are up to date.

•  Check whether your TV and the device you’re casting from are on the same Wi-Fi network. 
• Right-click on a video on the laptop you’re casting from, select Cast to Device, and choose your Chromecast device from the list to see if it helps.
• Disable any proxy services like a VPN that may be running in the background on your phone or computer.

Disable Real-Time Protection

If you’ve tried the quick fixes, but none of them worked, try temporarily disabling the real-time protection feature on Windows Defender and check if you can cast again. The real-time protection feature scans your downloads and programs you run on your device so make sure you turn it back on to keep your device safe from the threat of viruses or malware.

1. Open Windows Defender Security Center and select Virus & threat protection.

1. Select Virus and threat protection settings and disable the Real-time protection toggle switch.

Try to cast your content via Chromecast again to see whether the real-time protection feature is causing the problem. If not, enable Real-time protection again and try the next solution.

Enable the Load Media Router Component Extension

The Media Router Component extension is used to cast your browser to your Chromecast-enabled TV or Chromecast device. The extension should be disabled by default, but you can enable it and see if it fixes the Chromecast “Source not supported” error.

1. Open Chrome and enter chrome://flags/#media-router in the address bar.

1. Next, search for Router Component.

1. Change the setting from default to enabled.

Reset Chromecast

If all else fails and you’re still getting the “Source not supported” Chromecast error, try resetting your Chromecast back to its original state when you first bought it. You can reset your Chromecast device in the Google Home app on your mobile device, but it’s important to note that you’ll lose any settings or data stored on the device.

Streaming to your TV from another device via Chromecast is a great way to enjoy a movie on a bigger screen or listen to music on YouTube without annoying ads.
