Tools to work with Pion SFU

This is code sample of some actions to be performed with ion-sfu using apis and command line both.

• Load Testing (go run main.go laodtest)
• RTMP to Track (go run main.go rtmptotrack)
• Save to Webm (go run main.go savetodisk)
• Track to RTMP Publish (go run main.go stream)
• API Server (go run main.go server)
• Simple Gstreamer Send (go run main.go send)

This is not ready for production at all right now, rather its more experimental basis

I am using a slightly modified version ion-sdk-go https://github.com/manishiitg/ion-sdk-go

======= Zoom

For zoom to rtmp, we will first get a rtmp push url i.e get key via the rtmp/getkey api for a room name. Once we have the rtmp push we can put that url in zoom. zoom will start to push rtmp to our url and we can them publish that to our call
