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

问题描述

使用Chrome时，媒体约束被指定为：

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

其中，

当使用Firefox（Mac上的 35.0.1 ）时，根据规范应该是：

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

但是不起作用（冰失败！）

使用 O fferToReceiveAudio

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

可以正常工作。

行为？

解决方案

正确的格式（现在）是：

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

因为这是新的规范格式，并且都支持 Chrome浏览器和 Firefox 。

特别注意小写字母o，因为这确实发生了变化，投掷了不止一些人。希望你现在可以开始工作了。

另外请注意，这些不再是约束，只是选项。更简单。

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

When using Chrome, the media constraints are specified as:

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

which works fine.

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

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

But doesn't work (Ice failed!)

Using "OfferToReceiveAudio"

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

works fine.

Is this documented behaviour?

解决方案

The right format (by now) is:

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

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

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.

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