pub unsafe static AVMediaCharacteristicFrameBased: Option<&'static AVMediaCharacteristic>Available on crate feature
AVMediaFormat only.Expand description
A media characteristic that indicates that a track or media selection option includes content that’s frame-based.
Frame-based content typically comprises discrete media samples that, once rendered, can remain current for indefinite periods of time without additional processing in support of “time-stretching”. Further, any dependencies between samples are always explicitly signalled, so that the operations required to render any single sample can readily be performed on demand. AVMediaTypeVideo is the most common type of frame-based media. AVMediaTypeAudio is the most common counterexample. Also see -[AVAssetTrack hasMediaCharacteristic:] and -[AVMediaSelectionOption hasMediaCharacteristic:].
