1/6/2010

This enumerated type 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. The application can also 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 exclusive. The DMO can set one of these flags or neither, but not both.

Requirements

Header dmo.h
Windows Embedded CE Windows CE .NET 4.1 and later
