与WebRTC共享屏幕? [英] Screen sharing with WebRTC?

问题描述

我们正在探索WebRTC，但看到了关于今天可能实现和支持的冲突信息.

We're exploring WebRTC but have seen conflicting information on what is possible and supported today.

使用WebRTC，可以重新创建类似于join.me或WebEx的屏幕共享服务，其中:

With WebRTC, is it possible to recreate a screen sharing service similar to join.me or WebEx where:

• 您可以共享屏幕的一部分
• 您可以控制另一方
• 无需下载

今天使用任何WebRTC浏览器都可以做到吗? iOS上的Chrome浏览器怎么样?

Is this possible today with any of the WebRTC browsers? How about Chrome on iOS?

推荐答案

据我所知，目前无法使用任何浏览器，尽管Google Chrome团队表示他们最终打算支持这种情况(请参见其路线图上的屏幕共享"项目符号. );而且我怀疑这意味着最终其他浏览器也会随之而来，大概是IE和Safari引起了人们的关注.但是所有这些都可能要在二月之后的某个时候，那时他们应该最终确定当前的WebRTC标准并交付量产版本. (希望微软在工作中的最后一刻并没有解决这个问题.)可能我最近错过了一些东西，但是我一直在非常仔细地关注该项目，而且我认为屏幕共享甚至都没有做到这一点.进入Chrome Canary，更不用说dev/beta/prod了. Opera是唯一在WebRTC实施上与Chrome保持同步的浏览器(FireFox似乎落后了大约六个月)，而且我也没有看到该团队有关屏幕共享的任何信息.

To the best of my knowledge, it's not possible right now with any of the browsers, though the Google Chrome team has said that they're eventually intending to support this scenario (see the "Screensharing" bullet point on their roadmap); and I suspect that this means that eventually other browsers will follow, presumably with IE and Safari bringing up the tail. But all of that is probably out somewhere past February, which is when they're supposed to finalize the current WebRTC standard and ship production bits. (Hopefully Microsoft's last-minute spanner in the works doesn't screw that up.) It's possible that I've missed something recent, but I've been following the project pretty carefully, and I don't think screensharing has even made it into Chrome Canary yet, let alone dev/beta/prod. Opera is the only browser that has been keeping pace with Chrome on its WebRTC implementation (FireFox seems to be about six months behind), and I haven't seen anything from that team either about screensharing.

有人告诉我，现在有一种方法是 ，它是编写您自己的网络摄像头驱动程序，以便您的本地屏幕对WebRTC getUserMedia()API的显示就像另一个视频源.我不知道有人这样做过-当然，这将需要在有问题的计算机上安装驱动程序.在一切都说完之后，使用VNC或类似的东西可能会更容易.

I've been told that there is one way to do it right now, which is to write your own webcamera driver, so that your local screen appeared to the WebRTC getUserMedia() API as just another video source. I don't know that anybody has done this - and of course, it would require installing the driver on the machine in question. By the time all is said and done, it would probably just be easier to use VNC or something along those lines.
