Add basic deinterlacing support, i.e. bob-deinterlacing whereby only the selected field from the input surface is kept for the target surface. Setting gst_vaapi_filter_set_deinterlacing() method argument to GST_VAAPI_DEINTERLACE_METHOD_NONE means to disable deinterlacing. Also move GstVaapiDeinterlaceMethod definition from vaapipostproc plug-in to libgstvaapi core library. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>
