watchme | Reproducible watchers for research | Monitoring library

I am using this sample https://github.com/youtube/yt-watchme

I just imported the sample and set the ACCOUNT_KEY in MainActivity. Below is the Build gradle file

apply plugin: 'com.android.application'

whenever i run my program it gives me a blank screen. except the title name . below is the source code of my project. i also tried it by writing html code in app.component.html file but still it is displaying blank screen.

app.component.html

I have a WebSite integrated with SignalR. It functions well, and it has a button which sends popup notification to all clients who are online. It works well when I click on the button.

My API is in another project but in the same Solution. I want to send the above notification by calling from the API side. Basically, a mobile app will send a request to API and then API will send a notification to all online web clients.

Below code runs and not gives the notification nor any error.

Is this fundamentally correct? Appreciate your help

API code (at WebAPI project)

Is there a way, to detect to source of a change to a watched property in AngularJS?

For example (very rudimentary), I have the global value:

I am making application to broadcast phone video to youtube channel. I found this link https://github.com/youtube/yt-watchme.

While compiling my code I get error

libavutil not found in file avecode.h at code #include "libavutil/samplefmt.h

I also changed to #include "../libavutil/samplefmt.h" still same error.

Perhaps suggest any good rtmp library to broadcast phone video to youtube channel.

I tried youtube's watchme app for live streaming and I understand the code fairly. In my use case the user needs to be able to live stream to another channel. I understand there is a need of Stream key here, but I need a rough guidance on where I need to change in the code. Any hints or a rough idea would do too. I just need headstart.
