Frame Stepping Property Set
Decoders that implement frame-accurate seeking under Microsoft DirectShow must implement the AM_KSPROPSETID_FrameStep property set, which is used in conjunction with the IVideoFrameStep interface.
|Property Set GUID||AM_KSPROPSETID_FrameStep|
|AM_PROPERTY_FRAMESTEP_STEP||Instructs the decoder to begin a step operation and passes an AM_PROPERTY_FRAMESTEP structure that specifies the number of steps.|
|AM_PROPERTY_FRAMESTEP_CANCEL||Instructs the decoder to cancel the current step operation. No instance data is associated with this property.|
|AM_PROPERTY_FRAMESTEP_CANSTEP||The decoder returns S_OK on this instruction to indicate that it can perform frame stepping, S_FALSE otherwise. No instance data is passed when this property is set.|
|AM_PROPERTY_FRAMESTEP_CANSTEPMULTIPLE||The decoder returns S_OK on this instruction to indicate that it can step multiple frames at a time, S_FALSE otherwise. No instance data is passed when this property is set.|
