Pass The Microphone

Pass the Microphone is Video Chat software to support podcasters performing remote interviews.

Twilio integration

• Pass the Mic uses The Twilio Video Api to support the live conference view.
• https://www.twilio.com/docs/video
• We use a combination of the js sdk and the ruby gem
• the rooms are created by ruby gem to enable recordings
• Callbacks go to twilio_controller#events where the case statement for events from twilio, change and effect the room
• Data Tracks are used to handle the chatbox on the live screen, which is another offering from the video sdk

Recordings

• Recordings get sent to us from twilio as an event. "recording-completed"
• This fires off a sidekiq job that
  • saves the recording to s3
  • if it is an audio recording (mka format)
    • it then converts the recording to a wav file using ffmpeg on the servers (added through heroku buildpack)
    • And stores the wav file to s3

Mailgun

• Basic plan, get 100k emails free to start.
• Set up via smtp settings in production.rb

Authentication

• User models use devise for auth. They are Confimable, 10 day waiting period (set in devise.rb)
• Also set through devise.rb is the email that the confirmations come from (noreply@passthemicrophone.com)
• AdminUsers were added as the default through the active admin screen, but as far as I can tell not used anywhere

Authorization

• There's no authorization for Admin. Pundit is used for application authorization between guest and host.

Active Admin

• Straightfoward use case of the active_admin dashboard. Right now, only Accounts, and Users are being shown. But it can show any model that is in the db if you configure it in the app/admin folder

Twilio_event_channel

• this is the start of a action_cable channel to handle twilio events, but as it turns out the video sdk ships with a websocket implementation so development here was paused. However it did work, so if your looking for a action cable example that might be a good place to start.

Deployment

• production branch should be deployed to prod heroku with this command: git push heroku production:master
• master branch should be deployed to staging heroku with this commabd: git push staging master assuming that you have set git remote staging as staging heroku git url
