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.
