Firefox 中的 WebRTC OfferToReceiveAudio 错误 [英] WebRTC OfferToReceiveAudio error in Firefox

问题描述

我正在开发一个简单的示例来测试 WebRTC，我发现了以下奇怪的行为.

I'm developing a simple example to test WebRTC, and I've found the following strange behaviour.

使用 Chrome 时，媒体约束指定为:

When using Chrome, the media constraints are specified as:

mediaConstraints = {'mandatory': {'OfferToReceiveAudio':true, 'OfferToReceiveVideo':true}};

效果很好.

但是，当使用 Firefox(mac 上为 35.0.1)时，根据规范应该是:

However, when using Firefox (35.0.1 on the mac), according to the spec it should be:

mediaConstraints = {'offerToReceiveAudio':true,'offerToReceiveVideo':true};

但是不起作用(Ice 失败了！)

But doesn't work (Ice failed!)

使用OfferToReceiveAudio"

Using "OfferToReceiveAudio"

mediaConstraints = {'OfferToReceiveAudio':true,'offerToReceiveVideo':true};

工作正常.

这是记录在案的行为吗?

Is this documented behaviour?

推荐答案

正确的格式(现在)是:

The right format (by now) is:

offerOptions = {'offerToReceiveAudio':true,'offerToReceiveVideo':true};

因为这是新的规范格式并且受支持通过 Chrome 和 火狐.

as this is the new spec format and is supported by both Chrome and Firefox.

请特别注意小写的 'o'，因为这确实发生了变化，并且会引起不少人的注意.希望你现在已经可以使用了.

Take special care to note the lower-case 'o's, as this did change and threw more than a few people. Hopefully you got it working by now.

另请注意，这些不再是约束"，而只是选项".更简单.

Also note that these are no longer "constraints", just "options". Simpler.
