I scanned the W3C Media Resource 1.0 and it is about media metadata. I think Camera's properties are different than media metadata. There might be some overlap after the video is captured, but they are different. One is set on the camera device and the other is set on the storage media.

We did look at this as a replacement for Gallery API which can be accomplished by the Media Resource plus File Reader API.

Thanks
Dzung Tran,

Shouldn't camera metadata be associated with capture, especially when  
settable? It seems an application using the camera might wish to set  
white balance etc without going into a different API module.

Which reminds me, how are we coordinating  with the W3C Media  
Annotations WG? Should we be?
