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 |
| Property ID | Description |
| 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. |
