KeyFrameSpace |
Gets or sets the number of frames between key frames (key frame spacing). For example, if the rate is 5, then a key frame is taken every 5 frames. If the value is 0, then the first frame is the only key frame in the video. |

BYTE |
QFactor |
Gets or sets the quality factor for compression. The value range is between 1 and 9. Use 1 for fast compression and 9 for high compression. |
Parameters
|
FrameNumber |
The zero based number (position) of the frame to compress as a key frame. Use -1 to make the next passing frame a key frame. Valid values range between -1 and the total number of frames in the stream less one. Note that the filter do not know the total number of frames in the stream; so a number greater than the total number of frames in the stream will be accepted but will have no effect since it’ll not be reached. |
Description
Forces the frame at the specified position to be a key frame. The method will return S_FALSE if the frame at the specified position has already been compressed.
Returns
S_OK if succeeded, Error code otherwise.
