Hello guys! Is it possible to publish video/audio to Wowza using Safari for MacOS or iOS?

Yes it is, but the support can vary.

Wowza Streaming Engine™ [media server software](https://www.wowza.com/products/streaming-engine) version 4.7.7 and later supports [WebRTC streaming](https://www.wowza.com/products/capabilities/webrtc-streaming-software) and playback on Google Chrome, Mozilla Firefox, and Apple Safari (limited). When publishing WebRTC streams, it’s important to note that browser support for codecs varies. We recommend that you use VP8 video with either Opus or Vorbis audio for the best performance, but H.264 is the most broadly supported WebRTC codec.

Hi Rose! Tnks!

I can not publish using Safari (MacOS/iOS). Even using the example (html/publish/index.html) does not work.

does not work after:

```auto
peerConnection.createOffer(gotDescription, errorHandler);

```

PS: Changed newAPI to true. addStream does not work.

Could you specify what can vary? PS: I tried with Opus, Vorbis, VP8, h264.
