Description

Displays a scrolling chart showing the internal structure of a movie's video track. Frame thumbnails are displayed in decode order, display order, and track order; the reordering due to display offsets and track edits is illustrated. Information about individual samples is obtained using GetMediaSample2; information about many samples is obtained at once by using CopyMediaMutableSampleTable. Frames are decompressed at thumbnail size using ICMDecompressionSessions.
