kCMSampleAttachmentKey_PartialSync
Indicates whether the sample is a partial sync sample (type CFBoolean, default false).
Declaration
let kCMSampleAttachmentKey_PartialSync: CFStringDiscussion
A partial sync sample can be decoded without requiring any previous samples to have been decoded. Samples following two consecutive partial sync samples also do not require samples prior to the pair to have been decoded. To treat a sample as a partial sync sample, set a value of kCFBooleanTrue for both this key and the kCMSampleAttachmentKey_NotSync key.
