ExoPlayer GVR Extension

Description

The GVR extension wraps the Google VR SDK for Android. It provides a GvrAudioProcessor, which uses GvrAudioSurround to provide binaural rendering of surround sound and ambisonic soundfields.

Using the extension

The easiest way to use the extension is to add it as a gradle dependency. You need to make sure you have the jcenter repository included in the build.gradle file in the root of your project:

repositories {
    jcenter()
}

Next, include the following in your module's build.gradle file:

compile 'com.google.android.exoplayer:extension-gvr:rX.X.X'

where rX.X.X is the version, which must match the version of the ExoPlayer library being used.

Using GvrAudioProcessor

  • If using SimpleExoPlayer, override SimpleExoPlayer.buildAudioProcessors to return a GvrAudioProcessor.
  • If constructing renderers directly, pass a GvrAudioProcessor to MediaCodecAudioRenderer's constructor.
