2. Add OnFilterAdded event handler for SDK control. In our sample code, we use Video Capture SDK .Net.
private void VideoCapture1_OnFilterAdded(object sender, FilterEventArgs e)
{
if (e.Name.Contains("Deinterlace Filter"))
{
IDeinterlace deint = e.Filter as IDeinterlace;
if (deint != null)
{
deint.DeinterlaceType = (int)DScalerDeinterlaceType.Bob;
deint.IsOddFieldFirst = false;
}
}
}
This event fired for each added filter. We're checking the filter name and getting the IDeinterlace filter interface. In our sample, we changing deinterlace method to Bob.
Before Start method call, you must add Deinterlace filter using the following code:
VideoCapture1.Video_Filters_Add(new CustomProcessingFilter("Deinterlace Filter"));
