AVISTDINDEX_ENTRY structure (aviriff.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Contains one index entry for an AVI 2.0 standard index. This structure is contained in the AVISTDINDEX structure.

Syntax

typedef struct _avistdindex_entry {
  DWORD dwOffset;
  DWORD dwSize;
} AVISTDINDEX_ENTRY;

Members

dwOffset

The offset, in bytes, to the start of the data. The offset is relative to the value of the qwBaseOffset member of the AVISTDINDEX. The value is the offset of the actual audio/video data in the chunk, not the offset of the start of the chunk.

dwSize

The lower 31 bits contain the size of the data. The high bit is set to 1 if the frame is delta frame, or zero otherwise.

Remarks
