xc70203 / minivideoencoder

A modern video encoding platform for encoding videos optimized for streaming supporting modern encodings such as x264, x265, VP9 and AV1

MiniVideoEncoder

Mini Video Encoder (MVE) is a modern video encoding platform based on open-source tools and frameworks.

MVE is

• Scalable and portable
• Open-source
• Optimized for streaming, support multiple authoring specifications
• Support modern video and audio encodings (x264, x265, VP9, AV1)
• Support delivery via MPEG-DASH, HLS and Smooth Streaming)
• Support major DRMs (Google Widevine, Apple Fairplay, Microsoft PlayReady)

Installation instructions

//TODO

Development instructions

MVE consists of the following 4 required services and are stored in a separate folder:

• WorkflowDatabase
• WorkflowEngine
• WorkflowEncoder
• WorkflowPackager

WorkflowDatabase

The workflow database stores the state of the encoding jobs. MVE uses a MongoDB database.

For local development, the database can be started by executing docker-compose up in a terminal window in the WorkflowDatabase folder.

WorkflowEngine

The workflow engine is responsible for handling the incoming encoding jobs. It implements a REST api for receiving new jobs and requesting the status of encoding jobs.

For local development, the workflow engine can be installed and started by first executing npm install to install all dependencies and npm start to start the engine.

WorkflowEncoder

The workflow encoder is responsible for actually encoding the input video to the requested formats. Currently the encoder supports x264, x265 and VP9. The workflow encoder uses ffmpeg for encoding.

For local development, the workflow encoder can be installed and started by first executing npm install to install all dependencies and npm start to start the encoder.

WorkflowPackager

The workflow packager is responsible for packaging the encoded content. It can converts the multiple encoded output streams into an HLS or Dash package. The packager is also responsible for adding the optional DRM to the package.

For local development, the workflow packager can be installed and started by first executing npm install to install all dependencies and npm start to start the packager.

Additional tools I use for development

I use two additional tools for local development, Postman and MongoDb Compass Community.

I use Postman to use and test the REST API of the workflow enging. To be able to query the database, I use MongoDB Compass. Both are available for free.
