Overview

To validate lightning refapp on rdk 4.0 (rdk-generic-hybrid-image-raspberrypi) along with video playback, need to do some necessary code customizations/modifications in lightning refapp side for media player implementation provided by lightning-sdk framework and rdk library side for variable setting and url configurations.

Please follow the below instructions to validate lightning refapp on rdk-generic-hybrid-image.

Prerequisites

Before you follow the steps below, make sure you have installed all the required prerequisites in your dev PC - Node.js , npm, Lightning-CLI

...

• Lighting refapp integration into rdk-generic-hybrid-image-raspberrypi

1. login into raspberrypi and change directory:

$ ssh root@<<IP address>>

# after login into box 
$ cd /lib/rdk/

2. add startup_app_conf variable into referenceApp.sh config file

...

      After reboot app come up with a splash screen. Lighting application will launch instead of switcher app. Main menu screen is displayed which allows users to launch apps, vod, and play video content.

RefApp Video Playback

• RDK 4.0 (rdk-generic-hybrid-image) Vs LGI  RefApp (rdk-generic-hybrid-refapp-image)

Dependencies

• Lightning RefApp on Accelerator

  • Uses lighting sdk media player to play video, verified video playback using mp4 and HLS streams. 
  • Tested mp4 source: http://clips-media-aka.warnermediacdn.com/cnn/clips/2021-01/79895-97f21462b4db4236abcbd68a581[…]remarks-vpx-primary-58581-79895-1920x1080_8000k.mp4 
  • Tested hls source: //cdn.metrological.com/hls/greenland720.m3u8
  • Lightning (a javascript TV app development framework) refapp is a web based app, which runs on browser (supports WebGL). To run this wpe framwork or rdkbrowser2 is required.
  • sessionmanager, rmfstreamer, spark environment, nodejs and LGI based IP player not required.

• Lightning RefApp on rdk-generic-hybrid-refapp
  • uses rmfstreamer with sessionmanager and spark environment to play video streams (hls/dash) using (aamp and Liberty IPplayer)
