Hey there! I know how frustrating it is when your Oculus GO app plays audio but only shows that dark brown camera background instead of your 360° video. Let's walk through the most common fixes and checks to get your video showing up properly.

First: Verify Your VideoPlayer & 360 Sphere Setup #

This is the most likely culprit since 360° video needs a specific setup to render correctly:

• Fix your 360 video container:

  1. Create a standard 3D Sphere in your scene (right-click > 3D Object > Sphere).
  2. Flip its normals so the video faces inward: Select the Sphere, click the gear icon next to Mesh Filter in the Inspector, then choose Flip Normals.
  3. Resize the Sphere to wrap around your OVRCameraRig—a scale of (10, 10, 10) works well, and make sure its position matches the CenterEyeAnchor of your OVRCameraRig.

• Configure the VideoPlayer component:

  1. Set the Render Mode to Material Override (this is the right choice for 360 video on a sphere).
  2. Create a new material with the Unlit/Texture shader, assign it to your Sphere's Mesh Renderer, then drag this material into the VideoPlayer's Target Material field.
  3. Double-check your video source: Ensure your MP4 is in the StreamingAssets folder (or directly imported into your project) and that it's set to Video Clip in the VideoPlayer's Source dropdown.

Check OVRCameraRig & Camera Settings #

Even if your video setup is right, the Oculus cameras might be blocking or ignoring the video sphere:

• Culling Mask alignment:
  Open the LeftEye and RightEye cameras under your OVRCameraRig. Make sure their Culling Mask includes the layer your video Sphere is on (by default, this is the Default layer—don't uncheck it!).

• Clear Flags confirmation:
  The dark brown background comes from your camera's Clear Flags set to Solid Color. This is fine, but it means if your Sphere isn't rendering, you'll see this color. Ensure the Sphere is within the camera's field of view (which it will be if it's wrapped around the rig).

Validate Video File Compatibility #

Oculus GO has strict requirements for video files—even if it plays on your PC, it might not render on the device:

• Use H.264 encoded MP4 files (this is the only supported format for Oculus GO).
• Stick to recommended resolutions: 4096x2048 (for high quality) or 2048x1024 (for better performance). Avoid higher resolutions that might overload the device.
• Ensure your video uses an equirectangular projection (the standard for 360° video). Other projection types (like cubemap) won't work with a basic sphere setup.

Quick Additional Checks #

• Player Settings: Go to Edit > Project Settings > Player > XR Settings, make sure Virtual Reality Supported is checked, and Oculus is added to the list of VR SDKs.
• Video Playback Trigger: Ensure the VideoPlayer has Play On Awake checked, or add a simple script to start playback when the scene loads:

  using UnityEngine;
  using UnityEngine.Video;
  
  public class PlayVideoOnStart : MonoBehaviour
  {
      public VideoPlayer videoPlayer;
  
      void Start()
      {
          videoPlayer.prepareCompleted += (source) => source.Play();
          videoPlayer.Prepare();
      }
  }
  

• Debug Logs: Use adb logcat or the Oculus Debug Tool to check for errors like "Failed to decode video frame"—this can point to codec or file corruption issues.

If you go through all these steps, your 360° video should start rendering alongside the audio. Let me know if you hit any snags!
