The exact type name (m_obj_list_t) was removed in 2013. I don't think
this stub comment helps much with understanding this complicated thing
anyway (this code is for the --vf/--af options, and makes up almost half
of m_option.c).
This is used to detect whether any filters were changed. This code was
essentially ported to m_option.c.
One possible difference is how the old code did name comparison. It did
not actually compare the name (!?!?), so this might change behavior,
hopefully to the better.
Today, if window decorations are not present, either because they were
disabled, or because the platform doesn't support them
(eg: gnome-shell on wayland), there are no window controls, meaning it
is not possible to minimize/maximize/close a window without knowing
keyboard shortcuts.
While you can imagine various ways of offering client side decorations,
it is attractive to consider using OSC because that is functionality
that we already have.
The main work here is defining a separate input area from the main
OSC box with its own buttons, etc.
While we could probably handle auto-detection based on whether
decorations are present or not, it's manually controlled for now.
The window control logic is mostly disconnected from the OSC itself,
except in the case of the `topbar` layout, where there has to be
coordination so that the controls don't get drawn on top of each other.
I had to do fine-positioning of the buttons based on the font on
my system, so don't be surprised if it looks wrong elsewhere.
You could also argue that window controls should be unscaled, even
if the main OSC box is scaled, but I've not tried to do this.
We primarily care about pseudo-decorations for wayland, where
the compositor may not support server-side decorations. So let's
implement the minimize and maximize commands and return the
maximized window state.
If we want to implement window pseudo-decorations via OSC, we need a
way to tell the vo to minimize and maximize the window. Today, we have
minimized as a read-only property, and no property for maximized.
Let's made minimized settable and add a maximized property to go with
it. In turn, that requires us to add VOCTRLs for minimizing or
maximizing a window, and an additional WIN_STATE to indicate a
maximized window.
At least with gnome-shell (I know, I know), the compositor does
not provide the old window size when leaving the maximized state.
Instead, we get a toplevel_config event with a 0x0 size and no
additional states.
Today, we already save the window geometry to restore it when leaving
the fullscreen state, so we just need a small change for it to
kick in for leaving the maximized state. If I read this correctly,
we'll still respect the size passed by a compositor that actually
provides the old size.
Rather than hard-coding the edge grab zone width, we can make it
user configurable. It seems worthwhile to have separate configs
for pointer and touch usage as the defaults should be different,
and a user might have both input methods in use.
Today, we support resizing wayland windows when we detect a touch
event in a defined grab zone. As part of implementing
pseudo-decorations, we should have equivalent functionality for
mouse input. And if we detect support for actual decorations we
will not activate the grab zone as the decorations will provide this.
Use x11->opts instead of vo->opts. This doesn't matter currently, and
x11->opts is actually set to vo->opts. However, there's a chance that
either option access changes, or that the way backends integrate with
struct vo changes. This is just a preemptive change to make this less of
a mess, and it's generally a good idea to reduce accesses to struct vo
anyway.
The previous bunch of commits made this unnecessary, so this should be
a purely internal change with no user impact.
This may or may not open the way to future improvements. Even if not,
at least the property/option interaction should now be much less buggy.
Convert some remaining properties to work without the option-to-property
bridge. Behavior shouldn't change (except for the corner case that it
tries to reapply the new state when setting a property, while it used to
ignore redundant sets).
As it is the case with many of these changes, much of the code is not in
its final proper state yet, but is rather a temporary workaround. For
example, these "VO flag" properties should just be fully handled in the
VO backend. (Currently, the config or VO layers don't provide enough
mechanism yet as that all the backends like x11, win32, etc. could be
changed yet, but that's another refactoring mess for another time.)
Now nothing relies on this option-to-property bridge anymore, which
opens the way to even more refactoring, which eventually may result in
tiny improvements for the end user.
Until now, using a filter not in mpv's builtin filter list would assume
it's a libavfilter filter. If it wasn't, the option value was still
accepted, but creating the filter simply failed. But since this happens
after option parsing, so the result is confusing.
Improve this slightly by checking filter names. This will reject truly
unknown filters at option parsing time. Unfortunately, this still does
not check filter arguments. This would be much more complex, because
you'd have to create a dummy filter graph and allocate the filter. Maybe
another time.
The behavior is slightly different in a messy way. The change is in line
with the option-to-property bridge removal mentioned some commits ago
and thus is deemed necessary.
This attempted to restore the old filter chain if setting a new one at
runtime failed. This is not needed anymore, because changing the filter
chain is done in a "transactional" way now.
When changing filters at runtime (vf/af commands/properties), this could
crash due to a NULL pointer access. The code for comparing the old and
new option values (to detect changes) was simply buggy.
This function is dangerous, because it disables the already basic/week
type checking the option system has at all. I'm tend towards thinking
that all of its uses should be replaced.
This is preparation to get rid of the option-to-property bridge
(mp_on_set_option). This is a pretty insane thing that redirects
accesses to options to properties. It was needed in the ever ongoing
transition from something to... something else.
A good example for the need of this bridge is applying profiles at
runtime. This obviously goes through the config parser, but should also
make all changes effective, for which traditionally the property layer
is used.
There isn't much left that needs this bridge. This commit changes a
bunch of options (which also have a property implementation) to use
option change notifications instead. Many of the properties are still
left, but perform unrelated functions like OSD formatting.
This should be mostly compatible. There may be some subtle behavior
changes. For example, "hwdec" and "record-file" do not check for changes
anymore before applying them, so writing the current value to them
suddenly does something, while it was ignored before.
DVB changes untested, but should work.
These properties actually were removed/replaced, so there is no conflict
with the options of the same name anymore. For example, there is no
"audio-file" property anymore, but you still can set "audio-files" (and
--audio-file simply maps to --audio-files-append).
add_key_binding() makes the name argument optional (in weird Lua
fashion), which did not work if there were additional arguments. So
there is no way to avoid specifying a name while passing a rp argument.
Fix this, declare this way of skipping the argument as deprecated, and
allow passing name=nil as the preferred way to skip the name argument.
Handling the window with this function makes no sense, since windows
and kernels are not the same thing and don't share the same option list.
The only reason it's done is to make sure the char* points at the static
string rather than the dynamically allocated one, which we can do
manually in this function. Rewrite a bit for clarity/quality.
This is supposed to turn input.conf comments into inline documentation.
Whether this will be useful depends on whether there'll be a script
using this field.
This changes a small aspect of input.conf parsing fundamentally: this
attempts to strip comments/whitespace from the command string, which
will later be used to generate the command when a key binding is
executed. This should not have any negative effects, but there could be
unknown bugs. (For some reason, every command is parsed when input.conf
is parsed, but it still only stores the string for the command. I guess
that saves some minor amount of memory.)
Read-only information about all bindings. Somewhat hoping someone can
make a nice GUI-like overlay thing for it, which provides information
about mapped keys.
No reason to have this as bstr, just makes everything more complex.
Also clear mp_cmd.sender when it's copied. Otherwise it would be a
dangling pointer. Apparently it's never set to non-NULL in this
situation, but this is cleaner anyway.
Should be without consequences. I think this is less trouble, because
code frequently wants to add/remove bits for modifiers and key state
from key codes, and with this change you can't accidentally break it by
testing or removing bits from the old -1 value.
It did that because there was no other way. It used a lock-free ring
buffer, which does not support this. Use a "manual" ring buffer with
explicit locks instead, and drop messages from the start.
(We could have continued to use mp_ring, but it was already too late,
and although mp_ring is fine, using it for types other than bytes looked
awkward, and writing a ring buffer yet again seemed nicer. At least it's
not C++, where mp_ring would have been a template, and everything would
have looked like shit soup no matter what.)
In the referenced commit, I forgot about this part, and a client which
tried to use this was actually not woken up when needed.
(Also why the hell does the subject line of that commit say "removed"?)

Particularly for "any_unicode" mappings, so they don't have to
special-case keys like '#' and ' ', which are normally mapped to
symbolic names for input.conf reasons. (Though admittedly, this is a
pretty minor thing, since API users could map these manually.)
The key is never nil if it's invoked through the normal input path. The
key name could be "" if mp_cmd.key_name==NULL. This should not happen,
but there's no strong guarantee in input.c that it cannot happen, so
whatever.
The intended target for this is the mpv.repl script, which manually
added every single ASCII key as a separate key binding. This provides a
simpler mechanism, that will catch any kind of text input.
Due to its special nature, explicitly do not give a guarantee for
compatibility; thus the warning in input.rst.
I often watch sporting events. On many occasions I get files with the
same filename for each session. For example, for F1 I might have the
following directory structure:
F1/
FP1.mkv
FP2.mkv
FP3.mkv
Qualification.mkv
Race.mkv
Since usually one simply watches one race after the other, I usually
just rsync the new event's files over the old ones, so, for example,
Race.mkv will be replaced from the file for the last event with the file
from the new event.
One problem with this is that I like to use --resume-playback for other
kinds of media, so I have it on by default. That works great for, say, a
movie, but doesn't work so well with this scheme, because you can
trivially forget to pass --no-resume-playback on the command line and
end up 2 hours in, watching spoilers as the race results scroll down the
screen :-)
This patch adds a new option, --resume-playback-check-mtime, which
validates that the file's mtime hasn't changed since the watch_later
configuration was saved. It does this by setting the watch_later
configuration to have the same mtime as the file after it is saved.
Switching back and forth between checking mtime and not checking mtime
works fine, as we only choose whether to compare based on it, but we
update the watch_later configuration mtime regardless of its value.
