This enumeration specifies values for the dwSampleFlags member of the AM_SAMPLE2_PROPERTIES structure. These values describe the properties of media samples.

Syntax

enum tagAM_SAMPLE_PROPERTY_FLAGS { 
  AM_SAMPLE_SPLICEPOINT = 0x01, 
  AM_SAMPLE_PREROLL = 0x02, 
  AM_SAMPLE_DATADISCONTINUITY = 0x04, 
  AM_SAMPLE_TYPECHANGED = 0x08, 
  AM_SAMPLE_TIMEVALID = 0x10, 
  AM_SAMPLE_TIMEDISCONTINUITY = 0x40, 
  AM_SAMPLE_FLUSH_ON_PAUSE = 0x80, 
  AM_SAMPLE_STOPVALID = 0x100, 
  AM_SAMPLE_ENDOFSTREAM = 0x200, 
  AM_STREAM_MEDIA = 0, 
  AM_STREAM_CONTROL = 1 
};

Elements

  • AM_SAMPLE_SPLICEPOINT
    Sample is a splice point (it can be decoded without reference to previous data).
  • AM_SAMPLE_PREROLL
    Sample is a preroll sample.
  • AM_SAMPLE_DATADISCONTINUITY
    Indicates the start of a new segment.
  • AM_SAMPLE_TYPECHANGED
    Sample type changed.
  • AM_SAMPLE_TIMEVALID
    Time is valid.

  • AM_SAMPLE_TIMEDISCONTINUITY
    A time gap in the data starts after this sample.

    The pbBuffer member of the AM_SAMPLE2_PROPERTIES structure can be NULL in this case.

  • AM_SAMPLE_FLUSH_ON_PAUSE
    For live data only; indicates discard in the paused state.
  • AM_SAMPLE_STOPVALID
    Stop time is valid.

  • AM_SAMPLE_ENDOFSTREAM
    End of stream occurs after this sample.

    This is reserved for kernel streaming and DirectShow currently does not use it.

  • AM_STREAM_MEDIA
    Normal data stream identifier.

  • AM_STREAM_CONTROL
    Control stream identifier.

    A value greater than 0x7FFFFFFF indicates an application-defined stream.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
