RICOH THETA 360° Video Player

The RICOH THETA camera takes 360° in MP4 format. You can use standard Android and iOS video player libraries to play the videos in equirectangular format.

This project displays videos from the network and asset folder using the video_player Flutter plugin. It modifies the example from video_player.

Learning Objectives

This tutorial will teach you:

• RICOH THETA video files are standard MP4 video files in a 2:1 aspect ratio and can be viewed with standard mobile app video players
• 360° navigation will require a special 360 viewer with higher requirements for GPU hardware acceleration

Network Video

The application gets a video from a network URL using a github page. Below is an example of displaying a network video:

The package uses a VideoPlayerController to display the network video.

void initState() {
    super.initState();
    _controller = VideoPlayerController.network(
      'https://codetricity.github.io/flutter_video_display/ageda.MP4',
      closedCaptionFile: _loadCaptions(),
      videoPlayerOptions: VideoPlayerOptions(mixWithOthers: true),
    );

Asset Video

This example also gets video from the assets/ folder. Here is a part of a code for displaying the local video.

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.asset(file);

    _controller.addListener(() {
      setState(() {});
    });
    _controller.setLooping(true);
    _controller.initialize().then((_) => setState(() {}));
    _controller.play();
  }

ListView

Using the video_player package, a ListView of videos can be created.

The corporate logo is made using a Flutter stack overlay.

360 View

The application uses the video_360 package to show videos in 360 view.

Problems

• Currently, List View crashes when adding multiple videos
• When adding video360 to the project, received this error: Cannot fit requested classes in a single dex file. To solve the error, add androidx.multidex:multidex:2.0.1 to the build.gradle file. Also, add multiDexEnabled true.

  defaultConfig {
    ...
        multiDexEnabled true
    }

dependencies {
    ...
    implementation 'androidx.multidex:multidex:2.0.1'
}
