Hello I want to use an ultra low latency CDN How can I push to facebook and push ULL CDN to my mobile application? I refer to this example [https://www.wowza.com/docs/getting-started-with-wowza-streaming-cloud-ultra-low-latency-streaming](https://www.wowza.com/docs/getting-started-with-wowza-streaming-cloud-ultra-low-latency-streaming) ---

Hi @aries weng, thanks for the question. We do not support ULL streams to the FB player, but you can create a mobile playback app with our GoCoder SDK that would indeed support ULL streams. Using the Wowza Streaming Cloud REST API or user interface, you can send a single bitrate live stream from any H.264 IP camera or encoder to geographically distributed cloud-based servers over RTMP, RTMPS, RTSP, WOWZ or WOWZS. The servers then deliver the stream to **players that support WebSocket-based playback URLs.** - . We use our proprietary protocol WOWZ that is WebSocket based for ULL streams. - Playback using Wowza Player in supported browsers or mobile apps developed with Wowza GoCoder SDK [https://www.wowza.com/docs/how-to-use-wowza-streaming-cloud-for-ultra-low-latency-streaming](https://www.wowza.com/docs/how-to-use-wowza-streaming-cloud-for-ultra-low-latency-streaming) ---

So… can’t push the source stream to the ultra low latency CDN and push it to Facebook Rtmp at the same time? ---

Yes @aries weng, I confirmed with the engineers you can do this. You can push into a Wowza Streaming Cloud instance that then pushes the RTMP stream to FB and then a second stream target can be created for ULL( the ULL stream target goes through the CDN). It may add end to end latency since it would be adding a hop to the path. You can find articles and tutorials for both steps here: [https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing) ---

@Rose Power-Wowza Community Manager Is the process like this? So does Gocder receive a delay of 5 seconds? [https://i.imgur.com/Huis7S9.png](https://i.imgur.com/Huis7S9.png)
