Deep Dive Into Codebase

Code Pointers:

• These processes run together with WebService when spawn: https://github.com/giongto35/cloud-morph/blob/master/winvm/supervisord.conf

  [program:Xvfb] command=/usr/bin/Xvfb :99: Create Virtual Video Buffer at port :99
  [program:pulseaudio] command=pulseaudio: Create Virtual Audio (pulse). Don't need to bind to any port, app still can output audio to it.
  [program:syncinput] command=wine syncinput.exe : Script to listen from Web Message to simulate Windows OS Event

  [program:ffmpegaudio] command=ffmpeg -f pulse -rtp rtp://%(ENV_dockerhost)s:4004 : Audio encoding read from Virtual Audio and export Audio RTP stream at port 4004

• CloudAppClient is core CloudApp component interacting with those process https://github.com/giongto35/cloud-morph/blob/master/pkg/core/go/cloudapp/cloudapp.go#L68

  • Listen from Video stream at 5004 and push to Video Stream Channel: https://github.com/giongto35/cloud-morph/blob/master/pkg/core/go/cloudapp/cloudapp.go#L90
  • Listen from Audio stream at 4004 and push to Audio Stream Channel: https://github.com/giongto35/cloud-morph/blob/master/pkg/core/go/cloudapp/cloudapp.go#L94
