The IAMDroppedFrames interface provides information from a capture filter about the number of frames that the filter dropped. Applications can use this interface when capturing to determine the quality of the results.
Note Filters that expose this interface might implement only the IAMDroppedFrames::GetNumDropped and IAMDroppedFrames::GetNumNotDropped methods.
In addition to the methods inherited from IUnknown, the IAMDroppedFrames interface exposes the following methods.
| Method | Description |
| GetNumDropped | Retrieves the total number of frames that the filter has dropped since it started streaming. |
| GetNumNotDropped | Retrieves the total number of frames that the filter has delivered since it started streaming. |
| GetDroppedInfo | Retrieves an array of frame numbers that were dropped. |
| GetAverageFrameSize | Retrieves the average size of the frames that the filter has captured. |
