chrome.desktopCapture在“标签”上抛出错误作为DesktopCaptureSourceType [英] chrome.desktopCapture throws an error on "tab" as DesktopCaptureSourceType

问题描述

我正在开发Chrome扩展程序，我的要点是要记录一个浏览器选项卡，如 Screencastify Chrome扩展记录浏览器选项卡。我引用了 desktopCapture ，这是一个适用于屏幕和窗口作为DesktopCaptureSourceType的完美Chrome API，而对于Tab作为DesktopCaptureSourceType，它会引发错误：

desktopCapture.chooseDesktopMedia：标签捕获尚不受支持。

我在扩展的manifest.json中配置了所需的权限。任何人都可以为我提供一个解决方案吗？

PS：我只需要记录铬浏览器选项卡，不要求屏幕或窗口记录

解决方案

这是一个已知问题： https：// crbug .com / 488262

然而，您可以使用 chrome.tabCapture api。缺点是你必须在捕获标签和屏幕/窗口之间拆分你的界面，因为chrome.tabCapture没有提供相应的选择器。

为什么Google有两个独立的屏幕捕捉apis？好问题。

I am developing a chrome extension, and my point here is to record a browser tab , like Screencastify chrome extension records the browser tab. I referred desktopCapture , a chrome API which works perfectly for "screen" and "window" as DesktopCaptureSourceType, whereas for "tab" as DesktopCaptureSourceType, it throws an error as

desktopCapture.chooseDesktopMedia: Tab capture is not supported yet.

I have configured the required permissions in manifest.json of my extension. Could anyone suggest me a solution?

P.S : I need to record the chrome browser tab only, am not asking for a screen or window recording

解决方案

This is a known issue: https://crbug.com/488262

However, you can use the chrome.tabCapture api instead. The downside is that you will have to split your interface between capturing tabs and screens/windows, as chrome.tabCapture doesn't provide an equivalent picker.

Why does Google have two separate screen capture apis? Good question.
