This enumeration specifies values for the dwSampleFlagsmember of the AM_SAMPLE2_PROPERTIESstructure. 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,

};

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 pbBuffermember of the AM_SAMPLE2_PROPERTIESstructure 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
Windows Mobile Windows Mobile Version 5.0 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
