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.
