VR 360 Videos
Considerations for VR 360 VideosWhen working with VR 360 videos, consider the following factors:
- Source File Creation: VR 360 requires special cameras to record the VR 360 content. The scope of this document assumes knowledge of how to produce and edit VR 360 content for distribution on the web and in mobile apps. VR 360 Streams require much more bandwidth than flat video content.
- Specialized Requirements: VR 360 requires both rendering and framing of the VR 360-formatted stream, as well as the ability to control the camera angle. Therefore, any VR 360 video will be rendered with an additional player control capability to navigate the camera angle. In the source editing of the video, the default (zero) camera angle will be defined.
- VR 360 Streams require more bandwidth than flat video content. Because the viewable area on a VR 360 stream is only a small portion of the entire stream (the viewable area is typically only 10-20% of the video frame), it requires a much higher quality stream to achieve acceptable quality in the focused area. As a result, the threshold for sufficient network bandwidth is much higher for VR 360 content. To enable playback with minimal buffering and/or stall risk, viewers should have roughly 1.2-1.5x the connection bandwidth relative to the lowest bitrate available.
Ooyala Support for VR360 Videos
|Supported Browsers||For web environments, VR 360 playback is supported on all generally
supported browsers that are certified for support with the Ooyala V4 player (see
Supported Browsers and Operating Systems for Player V4).
Important: Only the Ooyala Skin SDK can be used with VR 360 videos. The default skin and custom skin cannot be used with the iOS or Android SDKs.

|Supported Device Hardware||While we are recommending at or near 4K video quality, many devices do not
have the processing resources needed to render h.264 4K video. Specifically, we have
found the following devices to struggle to play 4K video:

|Supported VR360 Types||
|Supported Streaming Formats||Currently,clear HLS and DASH, as well as eHLS streams, are supported with VR 360. By default, Ooyala provides a single-bitrate processing profile for any videos identified on upload as VR 360. This profile creates at minimum an ~8 Mbps HLS and/or DASH stream with a 4K resolution of 3840p. Ooyala ingestion maintains the source aspect ratio and calculates height dynamically, while the source frame rate is also retained from the source file.

Adding VR 360 Content to Your Backlot AccountYou can add VR360 content to Backlot in the following ways:
- Backlot UI
- Uploading a VR 360 video is similar to uploading a flat video. The main difference is that you identify the video as VR 360 and then specify whether the content is monoscopic or stereoscopic. See Uploading a Video for details.
- You can add a VR 360 video as a remote asset. See Adding a Remote Asset in Backlot for details.
- You can replace a video asset with a VR 360 video. See Replacing Content for details.
- Backlot API - Uploading a VR 360 video is similar to uploading a flat video. The main difference is that you specify the vr360type attribute as a query parameter to specify whether the content is monoscopic or stereoscopic. You can specify the vr360type in the initial POST /v2/assets call, or you can add it later using PUT /v2/assets/:embed/metadata. See Uploading VR 360 Content for details.
- Ooyala Ingestion Service (OIS) - Uploading a VR 360 video is similar to ingesting
a flat video, with the addition of metadata that is unique to VR 360 - label the file as
VR 360 and specify the VR 360 type (monoscopic or stereoscopic).
- You can set VR 360 file metadata in the manifest file (see Manifest File Formats).
- If you are not using a manifest file, indicate the file type by setting file metadata with the ffmpeg command-line utility (see Ingesting with FTP / FTPS or Ingesting with Aspera).
Managing VR 360 AssetsOnce stored in Backlot, you can manage and publish VR 360 videos just as you do flat videos.
Playing VR 360 VideosThe Ooyala Player automatically detects VR 360 streams and displays the applicable playback controls to navigate VR 360 videos. The following example shows the VR 360 icon on screen.
Changing the Camera AngleViewers have several ways in which to change the camera angle.
Switching Between Monoscopic and Stereoscopic ModesUse the following icon to switch between monoscopic and stereoscopic modes.
Customizing VR 360 Playback Using skin.jsonYou can configure Playback settings for VR 360 by modifying the skin.json file. See Customizing VR 360 Player Controls, as well as Customizing the Player V4 Skin with skin.json and Player V4 JSON Schema.
Ads and VR 360You can use any of the Ooyala player ad plugins with VR 360 monoscopic content, just as you would with flat videos. See Ads in Player V4.
Discovery and VR 360The Ooyala player fully supports mixing flat and VR 360 videos in the discovery recommendations. During playback, the player will adjust appropriately to the video format and reveal or hide the applicable UI and navigational elements. See Discovering Content in Player V4.
Playlists and VR 360The Ooyala player fully supports mixing flat and VR 360 videos in the same playlist. During playback, the player will adjust appropriately to the video format and reveal or hide the applicable UI and navigational elements. See Using Playlists in Player V4.
Analytics and VR 360Standard analytics events will be reported the same as other videos for Ooyala IQ as well as third-party analytics plugins. Reporting is automatic - no additional setup is required for VR 360 videos. The same metrics are tracked for VR 360 videos and flat videos. For supported Analytics integrations, see Analytics in Player V4.
VR 360 and Mobile SDK DevelopmentThe Ooyala Mobile SDKs provide the ability to play VR 360 content. It supports usage with both touch navigation of monoscopic VR 360 content, and with stereoscopic VR 360 content using head-mounted displays. With native iOS and Android apps, the videos can be navigated using the built-in device accelerometers to enable manipulating the camera angles with motion.
VR 360 Considerations for All Mobile SDKs
- Only the Ooyala Skin SDK can be used with VR 360 videos. The default skin and custom skin cannot be used with the iOS or Android SDKs.
- When presenting stereoscopic content in iOS or Android apps, touch and drag navigation is disabled. This is because navigation is assumed to be via the accelerometers in combination with a head-mounted display.
- If you are presenting stereoscopic videos, it is not recommended that you mix them with flat ads, as the user would be using a stereoscopic head-mounted device for viewing, and the flat videos would not display properly.
Syndication and VR 360
If you syndicate a VR 360 video to Facebook or Youtube, the asset is treated like a regular video, not a VR 360 video.
iOS and tvOS RequirementsTo support VR content in your iOS/tvOS app, you need to add the OoyalaVRSDK.framework or OoyalaVRTVSDK.framework as part of your app project. Do not include the OoyalaSDK.framework because they do not work well together. You will have access to everything that the OoyalaSDK.framework provides with the OoyalaVRSDK only. For sample apps:
- TVOS: For Apple TV, the TVoS sample app currently only presents the supported basic playback and navigation of VR 360 monoscopic content, using the remote control to navigate in a full-screen view.
Android RequirementsTo support VR content in your Android app, you need to add the OoyalaVRSDK.jar library as part of your app project. You should also include the OoyalaSDK.jar because it is a dependency of the OoyalaVRSDK.jar library.
Amazon Fire SDK Sample Apps for VR 360For Amazon Fire TV, the sample app currently only presents the supported basic playback and navigation of VR 360 monoscopic content using the remote control to navigate in full-screen view.
