This script uses the lavfi cropdetect filter to automatically
insert a crop filter with appropriate parameters for the
currently playing video.

It will automatically crop the video, when playback starts.

Also It registers the key-binding "C" (shift+c). You can manually
crop the video by pressing the "C" (shift+c) key.

If the "C" key is pressed again, the crop filter is removed
restoring playback to its original state.

The workflow is as follows: First, it inserts the filter
vf=lavfi=cropdetect. After <detect_seconds> (default is 1)
seconds, it then inserts the filter vf=crop=w:h:x:y, where
w,h,x,y are determined from the vf-metadata gathered by
cropdetect. The cropdetect filter is removed immediately after
the crop filter is inserted as it is no longer needed.

Since the crop parameters are determined from the 1 second of
video between inserting the cropdetect and crop filters, the "C"
key should be pressed at a position in the video where the crop
region is unambiguous (i.e., not a black frame, black background
title card, or dark scene).

The default options can be overridden by adding
script-opts-append=autocrop-<parameter>=<value> into mpv.conf

List of available parameters (For default values, see <options>)：

auto: bool - Whether to automatically apply crop at the start of
    playback. If you don't want to crop automatically, set it to
    false or add "script-opts-append=autocrop-auto=no" into
    mpv.conf.

auto_delay: seconds - Delay before starting crop in auto mode.
    You can try to increase this value to avoid dark scene or
    fade in at beginning. Automatic cropping will not occur if
    the value is larger than the remaining playback time.

detect_limit: number[0-255] - Black threshold for cropdetect.
    Smaller values will generally result in less cropping.
    See limit of https://ffmpeg.org/ffmpeg-filters.html#cropdetect

detect_round: number[2^n] -  The value which the width/height
    should be divisible by. Smaller values have better detection
    accuracy. If you have problems with other filters,
    you can try to set it to 4 or 16.
    See round of https://ffmpeg.org/ffmpeg-filters.html#cropdetect

detect_min_ratio: number[0.0-1.0] - The ratio of the minimum clip
    size to the original. If the picture is over cropped or under
    cropped, try adjusting this value.

detect_seconds: seconds - How long to gather cropdetect data.
    Increasing this may be desirable to allow cropdetect more
    time to collect data.

suppress_osd: bool - Whether the OSD shouldn't be used when filters
    are applied and removed.
