This is more stable in practice. Avoids switching between possibly
different hwdecs and avoids unnecessary init. Software decoding should be
more stable and possibly faster overall for decoding this small portion
of video needed for cropdetect.
I didn't set file-local-options/hwdec because you have to store the
hwdec value to restore it after cropdetect anyway, and if the user
manually changes hwdec after cropdetect, the new value isn't reset when
changing file.
If you change file while cropdetect is active and you try to crop the
next video, it fails with "Already cropdetecting!". This is because
timers.detect_crop wasn't cleared correctly, only the timer variable
local to the loop was being set to nil.
Gated behind option for backward compatibility.
Note that this will not magically start working with hwdec, as we do not
have crop detection for hwdec.
This reorders some code and checks the image track-list sub-property
instead of the albumart one, so that when playing audio without enough
playtime-remaining and images, the "autocrop only works for videos."
warning is logged instead of the "Not enough time to detect crop." one.
It also avoids repeating this warning twice in the code.
As of e16d0dd15d current-tracks returns a video track even when
lavfi-complex is used, so the track-list loop in is_cropable can be
replaced with just checking current-tracks/video while still cropping
videos with lavfi-complex.
Because having these on every video is annoying, and when you resume
from watch later files, the filters are applied immediately so they hide
your osd-playing-msg or equivalent show-text commands.
The previous code tried to disable autocrop for cover-art by testing
that track-list/$vid/albumart is false, however, $vid is completely
unrelated to the track-list index.
It only sometimes succeeded to disable for albumart, by accident,
e.g. with one audio track and one video track where $vid==1 and
track-list/1 happens to be the video (cover art) track.
The new code detects the currently-used video track by finding a track
with type=="video" and selected==true. Unlike the previous code, it
also works in scenarios with many audio/video/sub tracks.
Additionally, autocrop is now enabled also with lavfi-complex, which
should be considered an improvement. The previous code implicitly
disabled it with lavfi-complex because $vid is nil on such case.
- --lua and --lua-opts change to --script and --script-opts
- 'lua' default script dirs change to 'scripts'
- DOCS updated
- 'lua-settings' dir was _not_ modified
The old lua-based names/dirs still work, but display a warning.

It now inserts no filters and does nothing until the hot-key is pressed.
This makes it more suitable to be put in ~/.mpv/lua.
When the hot-key is pressed, it now inserts the cropdetect filter and
waits 1 second (or a --lua-opts specified duration) before gathering
the cropdetect metadata and inserting the appropriate crop filter. A
second press of the hotkey removes the crop.
