Quick demo for converting mp4 --> webm using firebase functions and fluent-ffmpeg. All major code can be found in functions/index.js

Create a new firebase project on the Firebase Console.

1. Deploy the project by using firebase init and firebase deploy in the directory.

2. Go to the Firebase Storage tab in the firebase console, and upload any webm file.

Firebase Functions have a timeout that's normally set to 1 minute. Due to the slow conversion speed of most video types, it's somewhat nessecary to increase the timeout duration.

To increase the duration:

• Go to the Cloud Function Console
• Click select when prompted to select a project and pick your newly created firebase project
• Click the three dots on the right next to the function, and click Test Function
• Click Edit
• Change Timeout to a bigger number (I chose 180 seconds, but more or less may be better)
