fix for ffmpeg not correctly reading width and height ratios of a rotated video when the pixel aspect ratio says otherwise.
added $data['dimensions']['aspect_ratio_fix_warning'] so that if the aspect ratio has automatically converted the width and height we know about it
added patch to the video output format post processor function updateFormatOptions that corrects the width and height dimensions of the final output if the input dimensions have been "fixed" from the aspect ratio data.
