AM_SAMPLE_PROPERTY_FLAGS

  • Article

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

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

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
