Go Class Memory Management

When I setup your sample rtmp-to-webrtc to the CentOS server, everything is built OK but the video is not played on the web page.

https://github.com/notedit/media-server-go/blob/master/incomingstreamtrack.go#L378

There currently does not seem to be a way to directly write data to an outgoing stream track, similar to the OnMediaFrame callback of the ingoing stream track.
Is there a possibility to add something like a WriteMediaFrame method?

after successfull installation of native libs installation of media-server-go fails with:

can we have a rtsptowebrtc demo?

here is a golang rtsp client:

Hello

I have some issue with building my app
$ GOOS=linux GOARCH=amd64 go build
../../../../notedit/media-server-go/activespeakerdetector.go:5:2: build constraints exclude all Go files in .../go/src/github.com/notedit/media-server-go/wrapper

How to handle the situation when the stream disconnects and should reconnect. Basically, what I want to do is wait 20 seconds after the initial disconnect, if the stream reconnects then it will resume as it is else it will stop and prompt user to create a new one.

So basically i need pause or resume functionality
