K-Link Video Streaming service

An API driven service for uploading, converting and delivering video streams.

Features

• Hosts and deliver mp4 videos
• Generate different video resolution for playback under different network conditions
• Support Dynamic Adaptive Streaming over HTTP (DASH) for media playback
• Support HTTP Live Streaming for media playback

Browser support

Target browser support includes modern web browsers: Edge 15+, Chrome, Firefox, Safari, Opera together with their mobile counterparts.

In addition to modern browsers we support IE10 (on best effort) and IE11. IE 9 and below are not supported.

Currently streaming is not supported on Safari and Mobile Safari (on iOS), we are working on it.

Getting started

Installation

The K-Link Video Streaming service is available as single Docker image

docker pull klinktech/k-link-video-streaming

An example usage is available in the Docker Compose Example file located in the root of this repository.

configuration

There are 3 parameters that must be configured in order to run the Docker image:

1. APP_URL: the URL on which the service will be publicly accessible, e.g. https://domain.com/video or https://video.domain.com
2. APP_KEY: the 32 characters random string to be used for encrypting cookies or other values that might need a secure storage
3. KLINK_REGISTRY_URL: the URL of the K-Link Registry service that will authorize applications to add or delete videos

By default the storage folder is not persisted, therefore is highly suggested to mount a volume pointing to /var/www/vss/storage.

If you are running the service behind a reverse proxy see Running behind a (reverse) proxy.

sub-folder deployments, like https://domain.com/video, are available only if the service is running behind a reverse proxy
