将Firefox标签记录为像chrome上的screencastify的视频 [英] Record the Firefox tab as a video like screencastify on chrome

问题描述

我想通过浏览器扩展来记录Firefox浏览器标签，如 chrome.tabCapture API用于获取当前活动的数据流并记录Web-RTC的流 RecordRTC.js 使用实验。像明智一样，Mozilla Firefox中是否有任何API来获取Firefox浏览器中的标签流。

PS：我正在询问有关记录Firefox的标签不记录屏幕或窗口或透过凸轮。

解决方案

多个特权apis ，可以让你捕获部分windows或xul元素到画布上下文中。然后，画布可以抓取到媒体流中。

I would like to record a firefox browser tab through browser extension like Screencastify extension does in chrome. About Recording Session of chrome extension , chrome.tabCapture API is used to get the stream of the currently active tab and to record the stream RecordRTC.js of Web-RTC Experiment is used. Like wise, Is there any API in Mozilla Firefox to get the stream of the tab in Firefox browser.

P.S : I am asking about recording the tab of the firefox not recording the screen or window or through cam.

解决方案

There are several privileged apis that let you capture parts of windows or xul elements onto a canvas context. The canvas can then be captured into a media stream.
