MPEG-DASH & HLS NodeJS Online Streaming

Streaming a video online requires a smart techonology. HLS and MPEG-DASH streaming allows us to stream any video over HTTP giving a great user experience. This application allows you to convert any standard video into HLS or MPEG-DASH Format and store it in Firebase Storage. The video has a unique URL which allows user to play the video in any supported player. 😄

Title: Sniper Will Smith (Gemini Man) Scene

Sample URL: Play in Shaka Player

Manifest URL: Copy Link

Credits: The video is not owned by me. All rights owned by Paramount Pictures

🔰 Setting Up the Project

1. The project has a few external dependencies listed below which are required, So I have made a bash script - dependencies.sh which can easily install and setup the required dependencies on Windows, MacOS and Linux. For Windows you just need to write ./dependencies.sh in Git Bash and for MacOS and Linux you need to run the same command in Terminal.
   • Bento4
   • Node Fluent FFMPEG
2. To start the project, first install the node modules via the command npm install and then to run the project in PRODUCTION mode use npm start and in DEVELOPMENT mode use npm dev.

    }
   

   Developer's Note:

   1. The API had been beautifully designed to handle edge cases like Max File Limit, Known File Types, Fallback in case of Failure.
   2. Multer Library has been used to handle the file upload.
   3. Proper Error Codes are also available to the user in Response.

2. Video Status API

   GET	api/admin/:sessionID/status	User must pass the session ID in the URL.

   Headers:

   Response:

    {
        "session": "f6b7c492-e78f-4b26-b95f-81ea8ca21a18",
        "contentId": 1642708128072,  
        "fileType": ".mp4",

            }
        },
        "publicURL": "https://storage.googleapis.com/nodejs-streaming.appspot.com/uploads/f6b7c492-e78f-4b26-b95f-81ea8ca21a18/1642708128072/manifest.mpd"
    }
   

   Developer's Note:

   1. This route is a ping route especially designed for frontend to show the current session updates and status of each job.
   2. I have maintained a status.json file under each session which contains the above information and is updated every time a job is processed in the backend.
   3. Once the status is successful, the publicURL of the video is visible in response.
