SDK 207 distributes side-by-side or top-bottom buffers between eyes within a Surface. Understand proportion, compatibility and validation.
Direct answer
Meta VR OS SDK 207 introduces Stereo Surface Composition for Android apps to present different content to each eye from a single Surface. The API accepts mono, side-by-side and top-bottom content in SurfaceView, VideoView or SurfaceControl. It only routes buffer regions: it does not convert 2D video to 3D or change codec or DRM. The implementation must synchronize source and mode, calculate aspect ratio across each eye's image, and validate depth and comfort on the device.
A buffer loads both views
Side-by-side puts the eyes side by side; top-bottom stacks them. The composer routes each region to the corresponding eye.
Proportion should use the dimension per eye
A 2560 by 720 side-by-side file represents two 1280 by 720 views. Treating the full width as display distorts the image.
Mode and source need to change together
Displaying stereo buffer as mono or selecting the wrong layout swaps regions between the eyes and can cause immediate discomfort.
Android pipeline reduces adoption barrier
Existing players can combine conventional controls and stereo media without rebuilding the entire application in an immersive engine.
Nexus Reading
Version format, resolution, aspect ratio and composition mode alongside the asset. The acceptance must check each eye, resizing, font switching, codec and hardware comfort.
FAQ
Does the API convert 2D video to 3D?
No. The content must arrive previously encoded in mono, side-by-side or top-bottom.
Does it work on any version of Horizon OS?
The feature requires Meta VR OS SDK 207 or later and must be checked for availability at runtime.
Does a screenshot validate the effect?
Not completely. Captures may show the packed buffer; binocular perception needs to be validated in the headset.
