If I force resolution to 720x576 using

    capture_dict = @{
        (id)kCVPixelBufferWidthKey  : @(720),
        (id)kCVPixelBufferHeightKey : @(576),
        (id)kCVPixelBufferPixelFormatTypeKey : pixel_format
    };


The video looks ok but resolution becomes 703(?)x576 

    Stream #0:0: Video: rawvideo (UYVY / 0x59565955), uyvy422, 703x576, 25 fps, 25 tbr, 1000k tbn, 1000k tbc


btw ntsc does not exposes the problem and shows:
    Stream #0:0: Video: rawvideo (UYVY / 0x59565955), uyvy422, 704x480, 29.97 fps, 29.97 tbr, 1000k tbn, 1000k tbc
