Yep, Lua is so crappy that the stdlib doesn't provide anything like
this.
Repurposes the undocumented mp.format_table() function and moves it to
mp.utils.
This isn't quite as robust as idet.sh as the default detection
interval is only 4 seconds vs 35 for idet.sh. idet.sh can have such a
large sample time since it turns off the vo and uses --untimed, which
is currently not possible from lua.
Commit e2e450f9 started making use of luaL_register(), but OF COURSE
this function disappeared in Lua 5.2, and was replaced with a 5.2-only
alternative, slightly different mechanism.
So just NIH our own function. This is actually slightly more correct,
since it forces the user to call "require" to actually make the module
visible for builtin C-only modules other than "mp". Fix autoload.lua
accordingly.
This will load other files in the same directory when a single file is
played. It's an often requested feature, but we definitely don't want it
in the core.
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.
