MBMS MW Android

Under Development Version License

Introduction

The MBMS Middleware for Android enables the reception of media content via 5G Broadcast and unicast (OTT streaming). Based on an MBMS Service Announcement the media manifests and segments are either received directly via 5G Broadcast or fetched via unicast from a CDN. The MBMS Middleware exposes the received media files via a local webserver to the MediaPlayer. As a result, the device can dynamically switch between broadcast and unicast consumption without the media player being aware of how the media files were originally received.

About the implementation

The implementation is basically a port of the MBMS Middleware to Android. It uses the MbmsGroupCallSession API for accessing packets received via 5G Broadcast.

Install dependencies

The MBMS MW Android requires Github Large File Storage to be installed before cloning the repository. Please check the Github documentation for details.

The resulting apk bundles can be found in app/build/outputs/apk. The debug build is located in debug folder the release build in the release folder.

Install

To install the apk on an Android device follow the following steps:

  1. Connect your Android device to your development machine
  2. Call adb devices to list the available Android devices. The output should look like the following:

  1. Install the apk on the target device: adb -s <deviceID> install -r app/build/outputs/apk/debug/app-debug.apk. Using -r we reinstall an existing app, keeping its data.

Running

After installing, the MBMS MW Android application can be started from the Android app selection screen.
