Media Stream Handler (Media Player) for 5GMSd

A Media Stream Handler (Media Player) enables playback and rendering of a media presentation based on a media player entry and exposing some basic controls such as play, pause, seek, stop to the 5GMSd-Aware Application. It consumes media from the 5GMSd AS at reference point M4d.

About the implementation

The 5GMSd Media Stream Handler is an Android library that includes the ExoPlayer as a dependency. The 5GMSd Media Stream Handler implements an adapter around the ExoPlayer APIs to expose TS.26.512 M7d interface functionality. Moreover, a MediaSessionHandlerAdapter establishes a Messenger connection to the Media Session Handler. The 5GMSd Media Stream Handler is included as an Android library by 5GMSd-Aware Application.

Include from local Maven Repository

To include the 5GMS Common Library from a local Maven repository apply the following changes.

Note: When using the other 5G-MAG client-side projects the changes below are already included. In this case the 5GMS Media Stream Handler only needs to be published to the local Maven repository ( see above).

1. Add mavenLocal() to your project gradle file

dependencyResolutionManagement {
   repositories {
   mavenLocal()
   }
}

2. Include the 5GMS Media Stream Handler in your module gradle file

Replace the version number in the example below with the version number you are using, e.g. 1.2.0 instead of 1.0.0.

dependencies {
    // 5GMAG
    implementation 'com.fivegmag:a5gmsmediastreamhandler:1.0.0'
}
