Commits 04018c3061cd7a7a1de8 introduced behavior that
updated window geometry during wayland events (specifically surface and
output). This is good but they also are too aggressive with
automatically resizing. For example, if a window is manually resized by
the user and then dragged to a different monitor with different geometry
than the initial monitor, mpv will automatically resize itself to the
window's resolution. The initial thought behind this logic was for
autofit to automatically readjust itself on a new monitor, but doing
that breaks other common use cases. An attempt could be made to
distinguish between autofit and a manual resize but that introduces a
lot of complexity for an edge case. It's better to simply not change the
window geometry here. Internal values are recalculated and scaled of
course, but wl->window_size and wl->geometry should not change.
nvidia follow the OpenGL spec very strictly, with two particular
consequences:
* They will give you the exact context version that you ask for,
rather than the highest possible version that meets your request.
* They will hide extensions that the specs say require a higher
version than you request, even if it's technically possible to
provide the extension at lower versions.
In our case, we really want a variety of extensions, particularly
compute shaders that are only available in 4.2 or higher. That means
that we must explicitly include a high enough version in our list of
versions to check for us to be able to get a 'good' enough context.
As for which version? We restore the 4.4 version that we had in the
old version selection logic. This is the highest version we ever asked
for, and we have separate logic that clamps the GLSL version to 4.4,
so anything newer wouldn't make a difference.
This possibility actually existed for years. The wayland protocol is
asynchronous and there's no restriction on when a compositor can send a
surface enter event. In mpv's case, the surface enter event is used to
set some vital things regarded geometry/scaling etc. However, this
implictly assumes that wl->current_output is actually initialized. The
vast majority of the time, vo_wayland_reconfig will happen first which
is where wl->current_output is, and should, be created. There's no
rule/law that the ordering of events will always occur in this order.
Plasma with certain auto-profile conditions can send the surface enter
event before mpv does its initial reconfig. That segfaults of course.
Just add a check to make sure we have wl->current_output here and return
if we don't. This assumes that the compositor will send us another
surface enterance event when mpv actually does the initial surface
commit and roundtrip request later. Wayland logs indicate this does
happen. Fixes#9492.
d2e8bc4499 was the the commit that
originally introduced the usage of this bit. As the message states, the
purpose was to force creating GLES 3 contexts on drivers that do not
return a higher version context than what was requested. With the recent
opengl refactors, mpv's gl selection has already moved away from such
complicated queries. Perhaps when that commit was added things were
different, but nowadays it seems like Mesa simply returns the highest
driver version available that is compatibile with the request (i.e.
requesting GLES 2 returns a GLES 3 context on my machine). In that case,
let's just simply drop EGL_OPENGL_ES3_BIT altogether as it does break
GLES 2 only machines. Fixes#9431.
Back when runtime updating of autofit/geometry was added for wayland and
x11 (commits: 4445ac828d and
ced92ba607 respectively), the naive
assumption was that window-related geometry would always be available.
While this is true 99% of the time, this isn't a guarentee. It is
possible for certain things such as loading shaders to delay starting up
the player. This causes autofit/geometry options to be registered as a
runtime update and triggers VOCTRL_VO_OPTS_CHANGED. This ends up calling
some geometry-related functions but this happens before the actual
values are available. Hence, a nullptr was accessed which segfaults. At
least one user experienced this with a combination of options in wayland
but in theory the same thing could happen under x11.
The fix is simple. Just be sure to check that the required geometry is
available before doing any calculations. In wayland, this would be
wl->current_output. Additionally add an assert to set_geometry (we
should never use this function without wl->current_output) to be extra
sure. In x11, the check is on x11->window. Later when the reconfig for
each backend actually happens, the autofit/geometry set by the user
happens anyway so ignoring it in this case does no harm. Fixes#9381.
Upstream libplacebo got refactored to use byte-sized strides rather than
texel-sized strides. This commit makes mpv's ra_pl wrapper take
advantage of that, rather than forcing a stride-fixing memcpy.
Note that, technically, we would still need a stride fixing memcpy in
cases when the true stride is not a multiple of the format's texel
*alignment*, however this is a much rarer case and extremely unlikely to
occur in practice, since all relevant formats use power-of-two texel
alignments.
In the reconfig event, the keepaspect option was checked before setting
the window_size geometry to the new params obtained from the vo. This is
incorrect. If a user disabled keepaspect on wayland, the video's size
would not change on a reconfigure event (i.e. loading a new video in the
playlist with a different size). No other windowing backend (x11, win32,
etc.) behaves like this or uses keepaspect in its code like wayland did
in this case. Clearly, this is not correct. Such functionality should be
handled by a separate option entirely. Just remove this if statement.
Based on the idea behind emersion's change to drm_info
(869e789a64).
Lets us by default skip devices which are not capable of doing what
the DRM master output requires (not primary devices), as some devices
have card0 actually not be such.
Negative part is that the number given to drm-connector is no
longer a direct mapping against a file name.
Upon re-examination I have no idea why this code was ever written or
what problem it was trying to solve. But, getting rid of it fixes#9291.
It might be a remnant from before 2af2fa7a27. Who knows. This code will
be replaced soon(tm) anyways.
Regression from e13fe1299d. Apparently,
Broadcom's EGL does not support the EGL_CONTEXT_FLAGS_KHR attribute nor
EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR. Just define these as EGL_NONE and 0
respectively if we do not have them.
With the recent refactor and quick look against the GLX code path, it's
fairly obvious, and trivial, how to add support for debug contexts.

Drop the gl3 suffix from the function name - it's no longer needed, with
the _old function gone.
Push the mpgl_min_required_gl_versions[] looping within the function,

while making the code neater.

The old/legacy code-path isn't really needed for mpv use-cases.
In particular:
All Mesa drivers (even GL 2.1 ones like lima/vc4) work fine with the
"non-legacy" path.
From proprietary/binary drivers - the vendor either does not support
desktop GL or the drivers/HW is not actively supported.
Looking at the Nvidia HW - anything GeForce 7 and older is GL 2.1 and
lacks decent video acceleration. The latest official drivers are from
2017.
All newer Nvidia HW is GL 3.3+ thus must have GLX_ARB_create_context as
in the non-legacy path, while also good acceleration albeit via VDPAU
in some cases.
With the old path gone, provide meaningful error message in the very
unlikely case that GLX_ARB_create_context is missing.

With earlier commit f8e62d3d82 ("egl_helpers: fix create_context
fallback behavior") we added a fallback for creating OpenGL context
while EGL_KHR_create_context is missing.
While it looked correct at first, it is missing the eglMakeCurrent()
call after creating the EGL context. Thus calling glGetString() fails.
Instead of doing that we can just remove some code - simply pass the
CLIENT_VERSION 2, as attributes which is honoured by EGL regardless of
the client API. This allows us to remove the special case and drop some
code.

The ra_gl_ctx_test_version() helper is quite clunky, in that it pushes a
simple check too deep into the call chain. As such it makes it hard to
reason, let alone have the GLX and EGL code paths symmetrical.
Introduce a simple helper ra_gl_ctx_get_glesmode() which returns the
current glesmode, so the platforms can clearly reason about should and
should not be executed.

As the documentation of the toggle says - the implementation can (and
will actually if they follow the GLX/EGL spec) return context version
greater than the one requested.
This happens with all Mesa drivers that I've tested as well as the
Nvidia binary drivers.
This toggle seems like a workaround for buggy drivers, yet it's lacking
context about the vendor and version.
Remove it for now - I'll be happy to reinstate it (partially or in full)
as we get concrete details.
This allows us to simplify ra_gl_ctx_test_version() making the whole
context creation business easier to follow by mere mortals.

Alike the GL commit earlier - the EGL spec essentially mandates that
implementation will return GLES 3.0+ (if supported by the driver), even
though only GLES 2 is requested.
The only thing we should watch out is - we should add both ES2_BIT and
ES3_BIT as EGL_RENDERABLE_TYPE.
This has been verified against the Mesa drivers (i965, iris, swrast) and
Nvidia binary drivers.

Currently mpv requires a bare minimum of GL 2.1, although it tries to
use 3.2+ core contexts when possible.
The GLX and EGL spec effectively guarantee that the implementation will
give you the highest compatible version possible. In other words:
Requesting 3.2 core profile will always give you core profile and the
version will be in the 3.2 .. 4.6 range - as supported by the drivers.
Similarly for 2.1 - implementation will give you either:
- 2.1 .. 3.1, or
- 3.2 .. 4.6 compat profile
This has been verified against the Mesa drivers (i965, iris, swrast) and
Nvidia binary drivers.
As such, drop the list to 320, 210 and terminating 0.

The ioctls were disabled a while back since they error out and allegedly
cause problem with X running in another VT.
Omitting the ioctls is not cool, even as a workaround.
If they fail, the user is supposed to fallback appropriately - use a suid
wrapper, logind-like daemon or otherwise.
As of kernel 5.10, they should just work in nearly all cases, so let's
just reinstate the calls.

The value of the border option should always match what the actual state
of the window is. Previously if a compositor rejected the request by
mpv, it did not correct itself. Also add some code to keep track of
decoration requests. Anytime the state is changed, make the last saved
request again (doesn't hurt and seems like intuitive behavior).
Unfortunately, this isn't foolproof since options only send callback if
the value is changed. (ex. on sway if the floating window has no border,
and then is titled, setting the border value to "yes" does nothing since
tiling the window already set the border value to "yes").
Fixes handle leak that happened whenever tvservice callback was invoked.
Powering on the TV causes HDMI unplug and attached events to be sent to
the tvservice callback.
This meant you could only power on/off your TV a finite number of times
before you were unable to allocate additional resources from VideoCore
(usually resulting in a "Could not get DISPMANX objects." error).
Furthermore because the VideoCore kernel driver does not cleanup handles
when a process dies, the only way to recover from the leak was to reboot
the RPI.
In wayland_common, wl->window_size keeps track of the window's size when
it is not in the fullscreen or maximized state. GET_UNFS_WINDOW_SIZE is
meant to report the size except for when it is fullscreen (hence UNFS).
However, the actual function was merely returning the wl->window_size so
it was wrong for maximized windows. Workaround this by returning
wl->geometry instead when we have the maximized case. Fixes#9207.
Previously, the initial positioning and fit ignored the borders, and
centered the content (the video itself) at the working area.
Now, the initial positioning centers the window, by subtracting the
borders (if needed) from the target area for the initial fit/position.
While this does mean that the initial maximum content area is now
smaller than before, ultimately this has no impact on the window size,
because fit_on_screen is called later and, if needed, further shrinks
the window to fit the borders too - but without centering the window.
So the net impact of this commit is only the initial positioning (same
size as before), which now centers the window instead of the content.
Note that on Windows 10 the borders include invisible areas at the
sides and bottom of the window (for mouse edge-drag), so visibly the
window is nearer to the top than to the bottom, but these are the
metrics we have (fit_on_screen uses the same border size values).
On Windows 7 it looks perfectly centered.
The --monitoraspect value is calculated at vo_calc_window_geometry2
(VCWG2) or VCWG3, and applied via vo_apply_window_geometry.
Before this commit, the screen size which the win32 VO used with
VCWG2 was the working area (screen minus taskbar). This allows better
fitting, but breaks the pixelaspect calculation which is derived from
the --monitoraspect value and this rectangle.
VCWG3 allows an independent size for the aspect calculations, and now
we use it independently of the fit size.
vo_calc_window_geometry2 (VCWG2) calculates both the pixelaspect and
the autofit sizes based on one "screen" rectangle.
However, these two calculations might need two different "screen"
rects if the fit should take into account decorations and/or taskbar
etc, while pixelaspect should be based on the full (monitor) rect.
VCWG3 does just that. It's the same as VCWG2, but with an additional
monitor rect which is used exclussively to calculate pixelaspect,
while the "screen" argument is used for fitting (like before).
VCWG2 now uses/calls VCWG3 with the same screen and monitor rects.
Currently yet unused.
This read-only property reflects the VO's dpi-scale value, and wasn't
supported on win32 until now (it is supported on wayland/x11/osx).
Currently in mpv it's only used by the builtin script console.lua,
and assumed 1 if unavailable.
When --window-scale=NUM is set from CLI, the dpi_scale value was/is
taken into account when the win32 VO calls vo_calc_window_geometry2.
However, when [current]-window-scale is read or set at runtime, it uses
the VOCTRL_{GET,SET}_UNFS_WINDOW_SIZE interface, where other VOs apply
the dpi_scale value internally (wayland, x11, osx), but the win32 VO
didn't before this commit.
Fixes two issues when --hidpi-window-scale=yes and dpi_scale != 1 :
- Incorrect window-size when setting [current-]window-scale at runtime.
- Incorrect current-window-scale value when reading it.
vo_calc_window_geometry2(...) is called to initialize the window
size with the dpi_scale value as one of the arguments.
dpi_scale is 0 initially, and set to a valid value at update_dpi(),
which is called from [force_]update_display_info().
However, no measures were taken to ensure that dpi_scale is set
correctly before vo_calc_window_geometry2() is called, which could
result in incorrect window size if it's not initialized.
It did happen to get initialized on time, by luck, because
VOCTRL_GET_DISPLAY_FPS is used early, which happens to call
update_display_info to read the fps value (other update_display_info()
calls are after the first vo_calc_window_geometry2() call).
This commit ensures that dpi_scale is initialized on time if needed.
Also, update_dpi() now ensures that dpi_scale is never 0.
This is a regression from cbbd81bb (the previous commit):
print_seq1 (which prints a sequence with 1 parametric byte value) is
used with 256 colors output, and apparently was never tested.
Two issues were introduced at the offending commit:
1. The ";5" part was incorrectly removed from the strings
ESC_COLOR256_{BG,FG} (affects both *nix and Windows).
2. On windows only - a semicolon was not used after the prefix.
Both issues resulted in an invalid 256 colors sequences and output.
On windows the UTF-8 strings are translated to wchar_t when printed to
the console, and some escape sequences are also translated, however,
this only works when printf is mapped to mp_printf, and for that to
happen we need to include osdep/io.h .
Normally in wayland, you receive a keymap event from the compositor
which is what allows the client to setup what is needed for xkb.
However, it turns out that this doesn't occur in the case of virtual
keyboards, such as from wtype, that come from the custom
virtual-keyboard protocol. What happens in this case is that mpv only
receives a keyboard entrance event. According to the wayland protocol
documentation [1], "the compositor must send wl_keyboard.modifiers event
after [the wl_keyboard.enter] event". It is possible for this to occur
before the physical keyboard is properly mapped (i.e: using a virtual
keyboard to start mpv). What this results in is a segfault once
xkb_state_update_mask is called in the modifiers event. The fix is to
simply not always assume we have created the xkb state if we get this
event and check for its existence first. Closes#9119.

Previous fullscreen handling code was removed in 59cdfe50b2 during
deprecation of VOCTRL_FULLSCREEN. Lack of this code caused the OSD layer
to be to be not resized along with the video layer when fullscreen is
toggled.
If a user attempted to change the window scale of a maximized window on
x11, nothing would happen since the window manager holds the size of the
window constant. Just do an unmaximize first before performing the
resize.
When the VT switch out is triggered, the decode thread (VD) falls back
to sw decoding. However, on the VO thread, which is responsible for
handling display preemption and presentation, vo_vdpau.c:reconfig() is
called. The reconfig() function returned -1 when the check_preemption()
returned 0. The vo_reconfig2() (which calls reconfig()) returned -1 in
turn which entered into an error handling path. This led to a series of
functions calls that ultimately set the in_terminate flag to TRUE.
This led the vo_thread to exit which ultimately led to the
MPV application exit.
The fix is to return 0 instead of -1 after the check_preemption() in
the vo_vpdau.c:reconfig(). Returning 0 instead of -1 is not fatal and
does not have any side effects. This is confirmed by testing the VT
switching behaviour. And as far as the frames that are going to the
display are concerned, they are now dropped. Since the display is
preempted, it is okay to drop the frames and continue.
Right after the listener is constructed, request a mode based on the
value of the border option. If border, then request SSD. If no border,
request CSD. The decoration listener handles it from there.
