memory failures due to large images.
@item apply_cropping @var{bool} (@emph{decoding,video})
Enable cropping if cropping parameters are multiples of the required
alignment for the left and top parameters. If the alignment is not met the
cropping will be partially applied to maintain alignment.
Default is 1 (enabled).
Note: The required alignment depends on if @code{AV_CODEC_FLAG_UNALIGNED} is set and the
CPU. @code{AV_CODEC_FLAG_UNALIGNED} cannot be changed from the command line. Also hardware
decoders will not apply left/top Cropping.
