Defines flags that describe an output stream.
Syntax
enum _DMO_OUTPUT_STREAM_INFO_FLAGS { DMO_OUTPUT_STREAMF_WHOLE_SAMPLES = 0x00000001, DMO_OUTPUT_STREAMF_SINGLE_SAMPLE_PER_BUFFER = 0x00000002, DMO_OUTPUT_STREAMF_FIXED_SAMPLE_SIZE = 0x00000004, DMO_OUTPUT_STREAMF_DISCARDABLE = 0x00000008, DMO_OUTPUT_STREAMF_OPTIONAL = 0x00000010 };
Elements
- DMO_OUTPUT_STREAMF_WHOLE_SAMPLES
- The stream contains whole samples. Samples do not span multiple buffers, and buffers do not contain partial samples.
- DMO_OUTPUT_STREAMF_SINGLE_SAMPLE_PER_BUFFER
- Each buffer contains exactly one sample.
- DMO_OUTPUT_STREAMF_FIXED_SAMPLE_SIZE
- All the samples in this stream are the same size.
- DMO_OUTPUT_STREAMF_DISCARDABLE
- The stream is discardable. Within calls to IMediaObject::ProcessOutput, the DMO can discard data for this stream without copying it to an output buffer.
- DMO_OUTPUT_STREAMF_OPTIONAL
- The stream is optional. An optional stream is discardable. Also, the application can ignore this stream entirely; it does not have to set the media type for the stream. Optional streams generally contain additional information, or data not needed by all applications.
Remarks
The DMO_OUTPUT_STREAMF_DISCARDABLE and DMO_OUTPUT_STREAMF_OPTIONAL flags are mutually exlusive. The DMO can set one of these flags (or neither), but not both.
