Events for when WebRTC input appears on HLS stream?

Hello,

I am using WebRTC as an input and am transcoding to H.264 and AAC and then broadcasting to an HLS stream. Currently, this process takes about 20 seconds for the video to transcode and then appear. Is there any way to get an event for when that WebRTC publish appears in the HLS stream. Also, in Wowza, is there any way to find out the Session ID without writing a custom module? For instance, can I find out the Session IDs or even the information above using the REST API or will I need to use the Java API to get this information.

Let me know if you have any questions. And I appreciate any help anyone can give. Thanks.
