I would like to build an iOS app which could insert 360 metadata into the video.
Facebook and Youtube needs the video associated with 360 metadata if you want to drag and browse the 360 video such like the link below. https://www.youtube.com/watch?v=-xNN-bJQ4vI
The statement below is about metadata specification.
Spherical video metadata is stored in a uniquely-identified moov.trak.uuid box to avoid collisions with other potential metadata. This box shall cite the UUID value ffcc8263-f855-4a93-8814-587a02521fdd. The metadata is required to be injected into specific location.
Could Intel VMF SDK inject metadata into specific location? Are there any iOS samples for Intel VMF SDK?
The best place for VMF issues is the the VMF Github page. https://github.com/01org/vmf/issues
As mentioned there, the short answer is yes. For details about how it will be best to continue your thread on Github.
