DMO_OUTPUT_DATA_BUFFER (Compact 2013)

  • Article

3/26/2014

This structure describes an output buffer used by a DirectX DMO.

Syntax

typedef struct _DMO_OUTPUT_DATA_BUFFER {
  IMediaBuffer* pBuffer;
  DWORD dwStatus;
  REFERENCE_TIME rtTimestamp;
  REFERENCE_TIME rtTimelength;
} DMO_OUTPUT_DATA_BUFFER, *PDMO_OUTPUT_DATA_BUFFER;

Members

  • pBuffer
    [in] Pointer to the IMediaBuffer interface of a buffer allocated by the application.
  • dwStatus
    [out] Status flags. After processing output, the DMO sets this member to a bitwise combination of zero or more DMO_OUTPUT_DATA_BUFFER_FLAGS flags.
  • rtTimestamp
    [out] Time stamp that specifies the start time of the data in the buffer. If the buffer has a valid time stamp, the DMO sets this member and also sets the DMO_OUTPUT_DATA_BUFFERF_TIME flag in the dwStatus member. Otherwise, ignore this member.
  • rtTimelength
    [out] Reference time specifying the length of the data in the buffer. If the DMO sets this member to a valid value, it also sets the DMO_OUTPUT_DATA_BUFFERF_TIMELENGTH flag in the dwStatus member. Otherwise, ignore this member.
