6863eefc3d handled this situation by using
an atomic variable to express the state for which the wakeup is caused
by AO control, and the dispatch queue is only processed at this state.
However, this can cause permanent lockup of the player core when the
following happens:
- AO control sets the thread state to WASAPI_THREAD_DISPATCH, and
sets the wakeup handle.
- WASAPI thread reads the WASAPI_THREAD_DISPATCH state and processes
the dispatch queue.
- Another AO control happens. A dispatch item is enqueued, and the
state stays at WASAPI_THREAD_DISPATCH.
- WASAPI thread resets the thread state to WASAPI_THREAD_FEED since
the state has not changed.
- WaitForSingleObject() returns in the WASAPI thread, sees this state,
and does not process the dispatch queue.
- The player core locks permanently because it is waiting for the dispatch
to be processed.
This has been experimentally verified on a system under high contention:
The easiest way to trigger this lockup is to continuously hold down "i",
which rapidly issues AO get volume/mute controls.
To properly handle this, use separate handles for system and user wakeup
requests. Only feed audio when woke up by system and only process the
dispatch queue when woke up by user.

bc28f7693d originally added this, but the
implementation isn't correct and causes excessive notifications when
writing to other options which may have bad behavior in some some
circumstances. Fix this by reworking the implementation for force
options so that the timestamps of the option update compared instead.
Whenever an option gets changed, the internal timestamp in the cache is
always incremented. For a special force option, we can save this
timestamp internally as well.
Because cache_check_update is always checked before potentially sending
an option notification, we know that if the internal timestamp is equal
to the timestamp saved by a force update option, it must have been
previously written. Thus, the notification can be sent. This lets
options like geometry work repeatedly but without constantly sending
notifications. Fixes#13954.
dead keys like tilde and accents were not reported because they returned
an empty string from the NSEvent.
try to retrieve dead key with alternative Carbon API when an empty key
is reported.
the Screen property localizedName returns a none unique dynamic name
that doesn't allow a specific selection of a Screen on every OS boot.
the name consists of the vendor name and model name (eg DELL U2723QE).
if the same model display is connected to the system several times,
macOS starts to add numbers to the localizedName (eg DELL U2723QE (1)),
that may not be associated to the same Screen on every OS boot or
connecting the display. it also changes the name of the first connected
display by adding that numeration. this makes it impossible specify the
proper screen with the screen-name option every time.
to circumvent this we remove the enumeration from the name and instead
add the serial number to the display-names property. this makes the
actual Screen unique and none dynamic. furthermore the selection of a
screen by name will check for equality for the old localizedName, simple
name without enumeration, serial number and the combined name with
serial number. this makes it possible to select the screen by either of
those names and identifiers, and keeps backwards compatibility with the
old behaviour.
Examples:
localized name (System Settings name): DELL U2723QE, DELL U2723QE (1)
simple name: DELL U2723QE
serial number: 123456789
combined name: DELL U2723QE (123456789)
When this was originally implemented, the fixed conversion factor was
accidentally reverse engineered. It was left as is though. Instead, use
the wl_fixed_from_int helper, so it's more obvious what is going on
here.
Currently they refer to the OSC documentation. However,
the "mp.options functions" already documents that, is more detailed,
and does not contain false statements like "there may be no spaces around
the ``=`` or anywhere else" (the primitive parser does not care about
them, so starting a string option value with spaces is perfectly fine).
Change them to refer to "mp.options functions" and remove the redundant
section in the OSC documentation.
mp_input_sdl_gamepad_add() calls mp_input_add_thread_src() which
already locks, so it cannot be called inside a lock.
Missed in e8b9476bf7 refactoring.
DXGI debug interface encapsulate multiple message queues, which allows
to get validation not only for D3D11 calls, but also DXGI ones.
Also this makes leak detector not report self debug interface as alive
like it was before. And same as with validation, it has ability to
detect more alive objects, not being limited to D3D11.
This allows users to set buffer duration in exclusive mode. We have
been using the default device period as the buffer size and it is
robust enough in most cases. However, on some devices there are
horrible glitches after a stream reset. Unfortunately, the issue is not
consistently reproducible, but using a smaller buffer size (e.g., the
minimum device period) seems to resolve the problem.
Fixes#13715.
Not all cards support gbm which means the creation of the gbm device
will fail. However during the uninit process, the destruction of the
device was unconditionally done which leads to a segfault. Guard it
instead. Fixes#13929.
Previously, the code required a check against the old saved geometry to
make sure the size and/or position was different before updating. The
doesn't work with the previous changes that allow a geometry value to be
set again with the same value as before. It would probably be nicer to
check against something that always keeps track of the actual window
size in real time, but it seems geometry in x11 doesn't quite work that
way so we'll do it the easier way instead.
mpv's core does not propagate option notifications unless they actually
change to the rest of the player. Most of the time, this makes perfect
sense. If the user sets fullscreen multiple times, there's no reason to
care about anything other than the change in state. However, there are
certain options where it makes sense to always broadcast a notification
even if the value doesn't change. For example, consider the window-scale
case. A user may set window-scale to some value, resize the window
further through some other means (such as mouse resizing) and then want
to set the window-scale again to the same value as earlier. The
window-scale value did not change from before so no notification is sent
and nothing happens even though it is desirable and expected that it
operates again.
This was solved by making the current-window-scale property writable a
few years ago, but actually the easier solution is to just always force
the option to update on any write. For the big callback, the needed
changes are trivial. Unfortunately, it requires a hot mess in order to
have this work with the m_config_cache_update APIs. Spooky stuff in
there, but it does send the notification now.
This option type is not used only by filter options: they're already
used by --ao, --vo, and --gpu-context. Replace the mentions of
"filter" to "item" instead, and changes some languages to improve clarity.
Also change the documentation on "Filter options" to describe what it
really is, and fix a typo.
Now that obj_settings_list is used for GPU contexts, detailed
descriptions can be added so that --gpu-context=help can print
the descriptions of the GPU contexts using standard
obj_settings_list help printing.
This adds a dummy context at the start of the context lists, which
serves three purposes:
- The "auto" option is listed for --gpu-context=help.
- Some special handlings of "auto" string are removed.
- Make sure that lists have at least one element, so MP_ARRAY_SIZE()
works as intended.
Since the list of available GPU contexts is a compile time constant,
use obj_settings_list instead of opt_string_validate for GPU contexts.
This has several advantages:
- Aligns with the existing usage of vo, ao, and filter lists.
- Allows custom probing order.
- Allows list option suffixes. (--gpu-context-append, etc.)
- Allows autocomplete in console.lua.
- Uses the standard obj_settings_list help printing, so the custom
help printing function is no longer needed.
This also deduplicates some context creation code for ra_ctx_create
and ra_ctx_create_by_name.
This gives these properties the "time" type, which allows them to be pretty-printed as HH:MM:SS easily (but also still allows raw formatting using e.g. ${=sub-start}).
This lets you press / in page 4 of the stats and type a keybinding or
part of its command to filter it by using mp.input.
This works badly without a VO because both stats.lua and console.lua use
show-text and only one can be displayed at a time, but it's still better
than not having the search available at all.
21d434d2db attempted to ignore unknown
CSI sequences with a specific termination rule. This however does not
apply to mouse CSI sequences which can have characters out of that
range. Fix this by throwing away the whole sequence when an unhandled
mouse sequence is detected.
These 6-byte codes have the format of \e [ M <button> <xpos> <ypos>.
Support the first 3 mouse bottons + scroll up/down for now as
button numbers > 5 are pretty non-portable across terminals.
Pixel-based mouse position values are calculated and sent to the
input system.
