"!=" is a comparing. "= !()" assign with a negate. Here is "= !()"
needed.

My fault.

The new patch is attached. Please integrate the patch. That I can

Subject: [PATCH] v3 fill AVFrame->interlaced_frame with
 MMAL_PARAMETER_VIDEO_INTERLACE_TYPE_T, add a pointer data[2] to
 MMAL_ES_FORMAT_T that user application can invoke MMAL components like
 deinterlacer and renderer with it
