BOOL SetFFmpegFilter (int FilterIndex, wchar_t *VideoFilterName, wchar_t *Parameters);

Used to activate a FFmpeg video filter.

Note: this feature requires the Datastead RTSP/RTMP/HTTP/ONVIF Source Filter to be installed.

Note: the filter must be an "in place" filter that outputs the same video format and video size than the input format.

Example:

VideoGrabber.SetFFmpegFilter (0, 'vignette', 'angle=PI/2:mode=forward:x0=w/2:y0=h/2:dither=0');

VideoGrabber.SetFFmpegFilter (1, 'vflip', '');
