Metadata Standards

Due to the increased complexity and number of variables in 360 video, there is a need for metadata standards to accommodate this. Google has a suite of standards and metadata injection tools on GitHub under the title of "spatial media" here.

In order to upload 360 video to YouTube and have it recognised and played back properly, it is required that spatial metadata be injected using the Google tool. This supports MP4 and WebM (video only) containers. You can find specification information on GitHub for the support elements for video and audio.

It supports:

• Projection type

• Stereoscopic mode

• Projection pose (yaw, pitch, roll) - presumably for initiation position?

• [Add audio]

Spatial Media Metadata Injector

Spatial Media Metadata Injector is a open source software that can be used to "convert standard" videos (equirectangular for example) to inject 360° / stereoscopic 3D (top/bottom) and spatial audio (ambix / sn3df) datas
