DMO_OUTPUT_DATA_BUFFER Structure

The DMO_OUTPUT_DATA_BUFFER structure describes an output buffer used by a Microsoft DirectX Media Object (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.
