VideoPlayer.SeekToPreviousFrame method

Previous pageReturn to chapter overviewNext page

Remarks

 

Steps to the previous video frame. This method can be called only when the video playback is in paused or stopped state; the current status can be obtained through the GetPlayerStatus method.

Not all video codec support frame stepping: certain video codecs like MPEG-1 and MPEG-2 will change the displayed frame only after a few calls to this method.

 

For further details about the use of the embedded video player see the VideoPlayer class section.

For details about video clips rendering refer to the How to play video files through DirectShow tutorial.
