Dudemanguy 162044ade9 wayland: check for xdg-decoration on border update
Oversight in 69c64f5. If there is no xdg_toplevel_decoration, don't
attempt to set the mode.

LaserEyess ec9083d0d8 options: clarify OS support for media keys
The previous wording gave the false impression that there was no media
key support for OSes besides Windows and macOS. This is untrue, the
option may only exist on those two platforms but it simply means that
media keys will always be enabled on other OSes as long as they are
supported.

Dudemanguy 69c64f5fc4 wayland: handle xdg-decoration protocol better
The current usage of the xdg-decoration protocol is quite a bit crude.
There's a specific listener struct for this like with most wayland
things, but mpv wasn't even using it. It also made no attempt to detect
if the compositor was telling mpv to use client side decorations. To
implement this correctly, first of all we need to create the decoration
listener object and add it like how most wayland things work. Secondly,
set_border_decorations needs to be changed to accept the uint32_t mode
given by the compositor. When we get the decoration event, pass the mode
obtained from the compositor to set_border_decorations. Update the mpv
border option, based on whether or not we have server side decorations
(yes if we have them; no if we don't). mpv can actually request either
client side or server side decorations with this protocol. This function
doesn't belong in set_border_decorations but rather it should be called
when the border option changes. Whether or not this request actually
works depends on the compositor (Plasma appears to allow it; sway does
not). If the compositor allows this request, then it gets handled by
configure_decorations. Note that the enum strangely starts at 1 hence
why there is an extra +1.

Dudemanguy 02323a184f command: check for monitor par in window-scale
When performing the scaling calculations, the window scale properties do
not bother checking for potential monitor par. The vo keeps track of
this via vo->monitor_par. Simply multiply/divide the video's width or
height depending on the value of monitor_par. We also clamp the values
to avoid the values running away to infinity in extreme cases.

Dudemanguy 9dc0857b3d command: check for rotation in window-scale
The vo currently handles rotations in 90 degree steps and some VOs set
this via VO_CAP_ROTATE90. When the rotation exactly hits either 90 or
270 degrees, this causes the values of dwidth and dheight to perfectly
swap like one would expect. However, the mp_image_params_get_dsize
function call in both of the window scale functions do not take this
special case into account. So the width/height values returned will be
incorrectly flipped in the 90 and 270 degree cases if the vo driver does
implement VO_CAP_ROTATE90 (like vo=gpu). Fortunately, the
mp_image_params struct keeps track of the rotation for us. So all we
need to do is check if the image is rotated at 90 or 270 degrees and
check that the current vo driver supports VO_CAP_ROTATE90. If so, then
swap vid_w and vid_h to their true, correct values.

Dudemanguy 77f2fd97f8 command: merge window-scale code together
Based on a small patch originally written by @avih. Instead of
duplicating the window-scale logic in update_window_scale, just call the
mp_property_current_window_scale function with the M_PROPERTY_SET action
and a NULL property.

Dudemanguy 8d4f10fcc0 wayland: fix keepaspect-window during resize
So the resizing mechanism is actually supposed to match the video size
to the window size while preserving the aspect ratio. In wayland, the
current logic behaves as if --no-keepaspect-window was set. Fix this by
simply multiplying the height by the same scale factor the width is
multiplied by. Also get rid of the pointless (width > height) test (it
makes no difference in any case) as well as some unneccesary checks for
the keepaspect-window option. The use of ceil here is to make sure the
window coordinates can never possibly have be 0 due to truncation
(weston can still give you a 1x1 window which is fun). Fixes #9098.

Dudemanguy 8300830951 wayland: improve behavior with touch events
There's currently some touch related code in mpv wayland, but clearly
nobody actually uses because it's a broken mess. Initially an attempt to
distinguish between two finger touches and one finger touch was made,
but there's not a good way to make this work. For whatever reason,
initiating either xdg_toplevel_resize or xdg_toplevel_move blocks any
other touch events from occurring (at least in plasma). Trying to call
these functions anywhere else is not really useful since the serial will
be invalid outside of the touch down events (well it would work in the
touch up event but that's just silly).

Anyways, let's just make this work sanely. Eliminate the touch entries
variable completely because it's pointless. Only one finger event is
ever considered at a time. Touches besides the initial one are all
ignored. If a user touches and drags within the touch edge radius, then
a resize event occurs. If the user touches and drags elsewhere on the
window, a move event occurs. A single tap displays the osc (which is
clickable if you tap again). A double tap toggles fullscreen.
Additionally, the default touch edge radius of 64 pixels is way too big
(at least I think so). Cut this in half to 32 which feels a lot better
(on a pinephone using plasma mobile anyway).

Dudemanguy 84362e820e wayland: correct window-scale behavior
The way the window-scale option is supposed to behave wasn't really ever
documented until 25cfc81. It turns out that different OS/WMs may do
slightly different things. For wayland, we need to fix two things.
First, only return the wl->window_size in GET_UNFS (aka don't return the
fullscreen size). For SET_UNFS, we need to change the behavior for the
maximized window case. If the window is maximized, first attempt to
unmaximize it and send the wayland event. If the compositor allows this
to happen, then go ahead and set the new dimensions and resize it. In
the case that the attempt to unmaximize is not successful, then don't
attempt the resize and just save the window size dimensions for later to
be used when the user unmaximizes the window.

Dudemanguy a0441ddb5e command: make current-window-scale writeable, 2nd attempt
The window-scale property mirrors the respective option (not the
effective scale derived from the current window size), and as such
setting its value to the same value it had before has no effect.
Specifically - the window will not resize.

This is consistent as far as property-option bridge behavior goes,
but we do end up with an issue that we can't set an arbitrary scale
and expect the window to always resize accordingly.

We do also have a current-window-scale property which does reflect
the actual window size, however, it's been read-only till now.

This commit makes current-window-scale RW so that it's now always
possible to set an arbitrary scale and expect the window to resize
accordingly (without affecting window-scale - like manual resize).

Also, mention window-scale no-effect-if-not-changed at the docs.

Based on code by @Dudemanguy from commit 873ae0d, with same effect.

Avi Halachmi (:avih) 2667dd6643 Revert "command: make current-window-scale writeable"
This reverts commit 873ae0de2a.

The next commit will restore this functionality, with the
following differences from the reverted commit:
- Smaller and simpler code change.
- On bad scale: use "Invalid value" (compared to "no such property").
- Doesn't combine the docs for window-scale and current-window-scale.
- Doesn't remove the docs for window-scale behavior prior to 0.31.0.

Dudemanguy 19c4ae004a wayland: keep track of toplevel width/height again
Regression from 24357cb. It's ugly but unfortunately keeping tracking of
the last toplevel width and height really is the best way to solve this
problem and removing it was a mistake. Compositors don't always send
width/height coordinates of the actual window. The easiest way to
trigger this is by changing window-scale/current-window-scale and then
unfocusing the window. The compositor will send another toplevel
configure event with coordinates of the window before the resize. Maybe
compositors could be smarter but multiple ones do this (sway, gnome,
plasma), so just keep the old workaround. The only difference this time
is that the toplevel width/height is saved at the very beginning which
also covers the case where it equals 0 (i.e. weston).

Dudemanguy 873ae0de2a command: make current-window-scale writeable
Somewhat confusingly, mpv has both a window-scale option and a
current-window-scale property. The documentation lists window-scale
under properties (and it is technically is one), but at its core it is
actually an option which means it behaves subtly different. Options in
mpv are runtime-configurable, but they only change anything if the value
of the option itself changes. window-scale is an option and not meant to
keep track of the actual scale of the window (intended behavior
introduced by d07b7f0). This causes window-scale to do nothing in
certain cases (ex: the window is manually resized and window-scale is
set to 1.00 again). This is logical and consistent with the behavior of
the rest of the mpv options, but it also makes it a poor candidate for
setting the mpv window scale dynamically.

As a remedy, we can just make current-window-scale writeable instead.
current-window-scale is intended to always report the actual scale of
the window and keep track of any window size changes made by the user.
By making this property also writeable, it allows the user to have more
intuitive behavior (i.e. setting current-window-scale to 1.00 always
sets the window to a scale of 1). Additionally, the default input.conf
is changed to use current-window-scale instead of window-scale. The
window-scale documentation under property list is removed since it is
already documented under options and users should probably set the
current-window-scale property instead in most cases.

Avi Halachmi (:avih) 41650203c3 sub: sub-filter-regex and jsre: support ass-to-plaintext
Using --sub-filter-regex-plain (default:no)

The ass-to-plaintext functionality already existed at sd_ass.c, but
it's internal and uses a private buffer type, so a trivial utility
wrapper was added with standard char*/bstr interface.

The plaintext can be multi-line, and the multi-line regexp flag is now
always set, but only affects plaintext (the ASS source is one line).

Avi Halachmi (:avih) 7c264950c0 sub: new: --sub-filter-jsre (js regex)
Pretty much identical to filter-regex but with JS expressions and
requires only JS support. Shares the filter-regex-* control options.

The target audience is Windows users - where filter-regex doesn't
work due to missing APIs, but mujs builds cleanly on Windows, and JS
is usually enabled in 3rd party Windows mpv builds.

Lua could have been used with similar effort, however, the JS regex
syntax is more extensive and also much more similar to POSIX.

Avi Halachmi (:avih) d82a073069 sub: SDH filter: use unified text-extraction utils 2021-08-05 21:32:22 +03:00
Avi Halachmi (:avih) 62704e2315 sub: SDH filter: small refinements
1. On a pathological case where event_format is NULL, previously the
   filter was trying to use it with each new sub - and re-failed. Now
   the filter gets disabled on init (event_format doesn't change).

2. Previously, if the filter didn't modify the text or if the text
   could not be extracted - it still allocated a new packet with same
   content. Now it returns the original, saving a whole lot of no-ops
   (there are still few allocations in this case though).

1 above is preparation for the next commit, and 2 was trivial, but
there's more to do if anyone cares (NIH string functions instead of
bstr, unused arguments, messages could be improved, and more).

Avi Halachmi (:avih) ab689a33a8 sub: add filter text utils, use from filter-regex (no-op)
Add two stand-alone function to help with the text-extraction task
which ass filters need. Makes it easier to add new filters without
cargo-culting this functionality.

Currently, on malformed event (which shouldn't happen), a warning is
printed when a filter tries to extract the text, so if few filters
are enabled, we'll get multiple warnings (like before) - not critical.

The regex filter now uses these utils, the SDH filter not yet.

Dudemanguy 24357cb7b5 wayland: cleanup handle_toplevel_config
The source of many geometry woes. There's some loosely related toplevel
things that should be cleaned up/fixed. First of all,
VO_EVENT_LIVE_RESIZING is actually completely useless. It might have
been useful sometime in the past, but there's no point. It doesn't
"speed up" resizing in any way and appears to be originally for cocoa.
Just remove it.

Way back in the day, toplevel_width/height was added as a workaround for
when we got uncoorperative (i.e. wrong) width/height coordinates from
the compositor in this event. Basically it could happen due to numerous
reasons but a lack of atomic commits was part of the reason and also
mpv's geometry handling then was a lot rougher. We *shouldn't* need this
workaround anymore. The width/height values are only used exactly when
we need them. If mpv sets geometry on its own, it should still be the
right dimensions.

Related to the above, mpv never actually propertly handled the case
where width or height was equal to 0. According to the xdg-shell spec,
"If the width or height arguments are zero, it means the client should
decided its own window dimension." An example of a compositor doing this
is weston. It's, unsurprisingly, broken. Getting out of fullscreen or a
maximized state does not restore the old window size like it should. The
right way to handle this is to just return near the end of the function
if we have a 0 for either argument and before any geometry is set
(wl->geometry's width or height can never be zero). Luckily, state
changes are already being detected so they just trigger the goto when
needed.

Finally, e2c24ad mistakenly removed the VO_EVENT_EXPOSE. There are edge
cases where this is needed and it's safer to just force a redraw here
when the window gets activated again. Just force wl->hidden to false
first and then trigger the expose.

Guido Cella dd7a49eb71 options: don't always set set-locally to true
Since 1d1d1fbff9 option-info/<name>/set-locally was being set to true
for every option. This broke setting start from ytdl-hook, which doesn't
overwrite start if it was set-locally. Fix this so that only adding an
option to reset-on-next-file or setting file-local-options/<name> make
set-locally true like before.

However, it's arguable that just adding an option to
reset-on-next-file without ever changing it should not make set-locally
true, so that e.g.
--reset-on-next-file=start 'https://youtube.com/watch?v=...&t=30'
will start at 30, though it currently doesn't.

Fixes #9081.

Avi Halachmi (:avih) 416668d3c8 stats.lua: page 4 (keys): better alignment of non-ascii keys
Previously we assumed the key-name string occupies strlen(name) cells,
now we count codepoints instead.

This improves alignment of non-english key names. Still not perfect
because we don't know if the key name is single or double width, but
wcwidth not available to scripts, notoriously unreliable (depends on
locale, correct and updated tables, etc), and also not always
available (Windows).

Still, better than nothing, and we err by at most one cell - vs up to
three before this commit (4 bytes keyname codepoint).

In the future we could do the alignment using libass tags, however,
this both complicates the ass-output generation, and also not available
when we output for the terminal, so for now only count codepoints.

Also, if the key name was in a right-to-left language, then previously
the name/command were swapped visually. Now we inject a left-to-right
marker before the name to ensure direction. This works also when
harfbuzz is disabled for libass (--sub-ass-shaper=simple).

Avi Halachmi (:avih) 8b1930fbd6 stats.lua: page 4 (keys): detect single-quotes 2021-07-30 09:52:34 +03:00
Avi Halachmi (:avih) 9f6cbf3a4d input: arguments quoting: support single-quotes
Users expect single quotes to work when the value includes literal
backslashes or double-quotes (or as general quoting like in shell).

The updated docs also include some previously-missing notes:
- newline is only supported in double quotes.
- adjacent (quoted) arguments don't join into one.

Supporting mixed quoting (adjacent quoted strings) would make
mpv's parsing more complete, but would require delicate effort of
larger scope, for two reasons:
- We'd need to also support escaping outside of quotes and do our
  best about backward compatibility.
- The parsed value can either be a substring of the input or
  a newly-allocated string, which would be delicate when joining.

Not critical to add right now.

Avi Halachmi (:avih) 73c9509720 input: argument custom quotes: use ` instead of !
Custom quotes were added in 4f129a3e and began with !, however, this
required quoting "!reverse" (used for the cycle-values command), which
is inconvenient, and was not taken into account when ! was chosen for
custom quotes. Also, ` is more natural for quoting than !.

This does break backward compatibility with the earlier form of custom
quotes, but at least we didn't make a release yet since custom quotes
were added (the last release - 0.33[.1] doesn't support it).

Dudemanguy e2c24adebe wayland: unset hidden state in frame callback
More wayland weirdness. So previously, flipping a hidden state from true
to false was done in vo_wayland_wait_frame. In theory, this would be
after you get the frame callback and all those events so there's no
problem. However since the function also does a bunch of
flushing/dispatching/etc. to the default display queue so a lot of
unknown things can happen before we actually set the hidden variable
back to false. For example if a single image was paused and left on
another virtual desktop long enough (~5 minutes) while also not having
focus, switching back to that desktop could render it a black frame.

This edge case was supposed to be handled by the surface being activated
again in the toplevel event but apparently that doesn't always work. The
fix is to just delete all of that junk and set wl->hidden = false in the
frame callback. What's actually happening is kind of a mystery honestly.
Probably the compositor drops the buffers after a while as an
optimization (sensible) and forces a repaint if you switch back to the
virtual desktop. Somehow wl->hidden not being set to false would not
properly trigger a repaint (likely because it also sends a toplevel
event which does stuff) thus you just get a black window. If you just
make sure to set hidden in the frame callback, it appears like all of
these problems and edge cases are solved. Since this event must happen
first, that makes sense. That simplifies a lot of stuff and fixes some
subtle bugs at the same time so just go with this approach.

Dudemanguy f8e62d3d82 egl_helpers: fix create_context fallback behavior
The EGL stuff is really complicated because of historical reasons
(tl;dr: blame EGL). There was one edge case with EGL context creation
that lead to incorrect behavior. EGL_KHR_create_context was created with
EGL 1.4 (which mpv does support) but it is still possible for an EGL 1.4
device to not implement this extension. That means that none of the EGL
attrs that pass a specific opengl version work. So for this obscure
case, there is a fallback context creation at the very end which simply
creates an EGLContext without passing any special attrs.

This has another problem however. mpv has a hard requirement on at least
desktop opengl 2.1 or opengl ES 2.0 to function (we're not asking for
much here). Since the fallback EGL context creation has no version
checking, it is entirely possible to create an EGL context with a
desktop opengl version under 2.1. As you get further along in the code,
the user will encounter the hard opengl version check and then error
out. However, we're supposed to also actually check if GLES works
(that's what the opengl-es=auto option is for) so this is a bug.

The fix is to do a bit of code duplication and make a mpgl_check_version
specifically for if we hit the edge case of needing to create an EGL
context without the EGL_KHR_create_context extension. Grab the version
with the function pointer, check if it's under 210, if so destroy the
EGL context and set it to NULL. After that, if the user has set
opengl-es to auto, mpv will try GLES next. If it is set to no, then mpv
will simply fail as desired. Fixes #5915.

Sidenote: the ra_gl_ctx_test_version originally testing 140 doesn't make
any sense. Passing the version number in that function only does
something if the user has set opengl-restrict. What we need to do is to
pass the version of the created context to that function. If the version
is higher than the opengl-restrict option, then make this a failure.

Avi Halachmi (:avih) 955736b7b7 stats.lua: fix ass-escape while persistent_overlay=yes
mpv has two methods to display output from text input:
- show-text (scripting: mp.osd_message) has ass disabled by default
  (escaped), and the property osd-ass-cc can control escaping.
- osd-overlay (scripting: mp.set_osd_ass or mp.create_osd_overlay)
  has ass enabled (unescaped), and osd-ass-cc is NOT supported.

By default, stats.lua uses mp.osd_message which does support escaping.
That's persistent_overlay=no.

When using persistent_overlay=yes then mp.set_osd_ass is used.

Due to this, the no_ASS(..) function - which is supposed to escape
ass, simply returned its input unmodified when persistent_overlay
is enabled.

This is not a new issue, and the filters on page 1 use no_ASS() to no
avail in persistent mode, however, this content (filter name and value
strings) rarely actually needs escaping, and users didn't notice.

However, the new page 4 (keys) does break visibly when no_ASS doesn't
work, because it tries to escape arbitrary key-names and command
strings, and at the very least the key '{' is bound by default, which
is displayed incorrectly if escaping doesn't work.

Fix this by rolling our own escaping when using mp.set_osd_ass,
similar to how the mpv code does it for mp.osd_message (substrings
replacements).

However, this means that the set_ASS(..) function can no longer
behave correctly because escaping requires going through the whole
content string rather than only inserting a marker.

Luckily, other than at no_ASS, set_ASS was only used at one place
(text_style), which is only called from two places:
- generate_graph() only needs to restore styles - not to enable ass.
- add_header() is only used at the begining of page output, and
  uses set_ASS to enable ass initially when using mp.osd_message.

So remove the set_ASS function, and instead enable ass directly at
print_page using osd-ass-cc when mp.osd_message is used.

Fixes #9022

Jan Ekström e2109b606b ci/travis: remove macOS builds
Quite unlikely to be run afterwards, and the macOS runner on
Github actions seems to work.

Dudemanguy 747b152001 context_drm_egl: allow autoprobe selection
This was explictly coded to avoid the autoprobe way back when in
2015[1] with no real explanation. In theory, there shouldn't be any
issues allowing this. If a user runs mpv in tty, this is probably what
they actually want in most cases. Perhaps something strange happens on
nvidia, but it should just fail anyway during the autoprobe.

Avi Halachmi (:avih) 5ed0338eea js: fix tiny leaks if js_try throws(!)
As it turns out, js_try can throw if it runs out of try-stack
(without/before entering either the try part or the catch part).

If it happens, then C code which does allocation -> try will leak.

In mpv there were two places which do alloc and then try, one of
them as part of the autofree system. On both cases the leak is the
smallest possible (zero allocation) - talloc_new(NULL);

It's very unlikely to trigger - an autofree mpv API should be called
when the try-stack is exactly full, and our next try will throw
(and guaranteed to get caught at an outer level, but with a leak).

Fix that by doing the allocation inside the try block, so that if
try throws before it's entered then nothing got allocated/leaked.

Mujs internal code also has/had similar leaks, which are getting
fixed around this time (July 2021, post mujs 1.1.3).

[1] exhaust the try-stack or call-stack, whichever comes first:
      function kaboom() { try { kaboom() } catch(e) {} }

Guido Cella 36b7cff582 manpage: fix watch-later-options examples
--watch-later-options-remove doesn't accept multiple options, so split
the example.

Also suggest the more correct -clr to empty the list, and remove the
workaround to not print an error with --watch-later-options=

Avi Halachmi (:avih) 7f4841ff39 js: key bindings: ensure priorities for same-key bindings
Previously, if a script bound the same key more than once to different
functions (without removing the older bindings first), then pressing
the key triggered any of the bound functions arbitrarily[1].

Now the newest binding for the same key is always the active one.

If the newest binding is then removed - the second-newest will become
active, etc. (same mechanism as before, except that the active key
was not always the newest).

[1] The order was implementation-defined, however `for (name in obj)'
    happens to iterate. With mujs that's currently alhabetic order,
    and name is from mp.add_[forced_]key_binding(key, name...)
    or generated internally if name is not provided. So a binding with
    higher alphabetic `name' value had priority over lower name value.
