Description James Craig 2016-08-11 01:28:51 PDT
AX: video autoplay (even for silent videos) should be disabled when iOS "Reduce Motion" setting is enabled, or Safari should have its own setting, "never autoplay."

Background
https://webkit.org/blog/6784/new-video-policies-for-ios/

API on iOS 8 and later:

// Returns whether the system preference for reduce motion is enabled
UIKIT_EXTERN BOOL UIAccessibilityIsReduceMotionEnabled() NS_AVAILABLE_IOS(8_0);
