vo_opengl used to have it as sub-option, which made it very hard to pass
down option values to backends in a generic way (even if these options
were completely backend-specific). For --opengl-dcomposition we used a
VOFLAG to deal with this. Fortunately, sub-options are gone, and we can
just add it as global option.
Move the option to context_angle.c and add it as global option. I
thought about adding a mechanism to let backends declare options, which
would get magically picked up my m_config instead of having to add them
to the global option list manually (similar to VO vo_driver.options),
but decided against this complexity just for 1 or 2 backends. Likewise,
it could have been added as a single option to avoid the boilerplate of
an option struct, but then again there are probably going to be more
angle suboptions, and it's cleaner.
Scale the window by the assumed DPI scaling factor, using 96 DPI as
base. For example, a screen that reports 192 DPI is assumed to have a
DPI scale factor 2. The window will then be created with twice the size.
For robustness reasons, we accept only integer DPI scales between 1 and
9. We also error out if the X and Y scales are very different, as this
most likely indicates a multiscreen system with botched size reporting.
I'm not sure if reading the X server's DPI is such a good idea - maybe
the Xrdb "Xft.dpi" value should be used instead. The current method
follows what xdpyinfo does.
This can be disabled with --hidpi-window-scale=no.
our constrainFrameRect prevents our window from positioning itself ontop
of the menubar, which is unwanted for a fullscreen window. this always
positioned our window vertically at -22/-23pt when going into fullscreen
because of the menubar. this bug doesn't show on newer versions of OS X
since the various flags we set force the window position. on OS X 10.9
though the fullscreen window was shifted 22pt downwards. even though
this bug doesn't show on newer OS X versions, it should still be fixed
for a possible behaviour changes in future version.
Fixes#4044
everytime we switched to a new video file a new displaylink was
initialised and started, but the old one was not stopped and released
beforehand. this lead to several displaylink callback calls per swap,
depending on how many files were switched beforehand. moving the
displaylink init call to the cocoa init functions will ever only init
one displaylink.
Fixes#4031
we are calling the method on a NSWindow object that may not respond to
that call, since its a method of MpvVideoWindow. add the method to our
protocol and rename that protocol to reflect the change.
in some circumstances cocoa isn't able to enter or exit fullscreen but
we still set window sizes and flags accordingly. this leaves us in a
hanging state between fullscreen and window. it also prevents the
toggleFullscreen method and its events to work properly afterwards. in
that state it's impossible to enter or exit this 'semi-fullscreen'.
add a proper fallback to recover from this state.
Fixes#4035
Introduce the --opengl-hwdec-interop option, which replaces
--hwdec-preload. The new option allows explicit selection of the interop
backend.
This is relatively complex, and I would have preferred not to add this,
but it's probably useful to debug certain problems. In exchange, the
"new" option documents that pretty much any but the simplest use of it
will not be forward compatible.
Replace the old code, that played games to evade thread-safety issues,
with newer thread-safe option access functions.
This also means mp_opengl_create() doesn't need to cache the hwdec
settings anymore. (They're applied in mpv_opengl_cb_init_gl() instead.)
Use the libavutil vdpau frame allocation code instead of our own "old"
code. This also uses its code for copying a video surface to normal
memory (used by vdpau-copy).
Since vdpau doesn't really have an internal pixel format, 4:2:0 can be
accessed as both nv12 and yuv420p - and libavutil prefers to report
yuv420p. The OpenGL interop has to be adjusted accordingly.
Preemption is a potential problem, but it doesn't break it more than it
already is.
This requires a bug fix to FFmpeg's vdpau code, or vdpau-copy (as well
as taking screenshots) will fail. Libav has fixed this bug ages ago.
Because it allows easier testing of filters + hwdec.
Make the texture setup code a bit more generic so it doesn't get too
much of a mess. We also use the GL renderer utility function
gl_find_unorm_format(), which saves us additional work with OpenGL's
semi-redundant format specifiers.
EGL rendering + new decode API didn't work due to a certain libva bug
with sort-of legacy API use hitting again. It will report the wrong
vaapi pixel format. It's old code and always nv12 anyway, so stop
worrying about it.
There are going to be users who have a Mesa installation which do not
support 10 bit, but a GPU which can decode to 10 bit. So it's probably
better not to hardcode whether it is supported.
Introduce a more general way to signal supported formats from renderer
to decoder. Obviously this is imperfect, because it still isn't part of
proper format negotation (for example, what if there's a vavpp filter,
which accepts anything). Still slightly better than before.
I don't know any way to probe for vaapi dmabuf/EGL dmabuf support
properly (in particular testing specific formats, not just general
availability). So we stay with the current approach and try to create
and map dummy surfaces on init to probe for support. Overdo it and check
all formats that AVHWFramesConstraints reports, instead of only NV12 and
P010 surfaces.
Since we can support unknown formats now, add explicitly checks to the
EGL/dmabuf mapper code to reject unsupported formats. I also noticed
that libavutil signals support for RGB0/BGR0, but couldn't get it to
work. Remove the DRM formats that are unused/didn't work the way I tried
to use them.
With this, 10 bit decoding + rendering should work, provided you have
a capable CPU and a patched Mesa. The required Mesa patch adds support
for the R16 and GR32 formats. It was sent by a Kodi developer to the
Mesa developer mailing list and was not accepted yet.
For surfaces allocated by libavutil, we assume that the sw_format (i.e.
in hw_subfmt in mp_image_params) is always correct. The API guarantees
that it explicitly sets the equivalent vaapi format on surface
allocation.
For surfaces allocated by mpv's old vaapi code, we explicitly retrieve
the format right after decoding. Unless the driver magically changes the
format asynchronously, it will still be correct once the surface reaches
the renderer.
In both cases, checking the format again is obviously redundant. In
addition, it doesn't require us to maintain a libva fourcc <-> mpfmt
table and the va_fourcc_to_imgfmt() function. This also unbreaks 10 bit
rendering support (still disabled by default).
This does not work, because Mesa has no support for the proposed
DRM_FORMAT_R16 and DRM_FORMAT_GR16 formats. It's also untested of
course.
As long as video/decode/vaapi.c doesn't hand down P010 surfaces, this is
fine anyway.
This can be tested by removing the code that disables P010 output:

mp_image_hw_download() is a libavutil wrapper added in the previous
commit. We drop our own code completely, as everything is provided by
libavutil and our helper wrapper.
This breaks the screenshot code, so that has to be adjusted as well.
the display refresh rate can't be estimated
correctly in some cases and just increases till it
turns off display-resample. cases are
off-screen rendering (different space), mpv
being completely hidden behind another window or
the mission control view.
this utilise the unused displaylink callback to
limit the refresh rate to the actual display
refresh rate.
This flips the y-coordinate to be consistent with
other platforms and the manual. furthermore it
fixes an unwanted behaviour of the cocoa
convertRectFromBacking method, where the x- and
y-coordinate was divided by the same factor as the
width and height instead of placing the new scaled
rectangle at the same relative position as the
original unscaled rectangle, by manually
calculating the new position.
Fixes#3867
I'm not sure what systems have <sys/poll.h> (maybe there are historical
reasons why some would), but POSIX defines <poll.h>. Although this code
is full of highly OS specific calls (like ioctl()), there's no reason
not to use the more standard include path.
vo_wayland_wait_events() is going to return when its time to swap the
buffers anyway, calling request_frame() before makes no sense.
Fixes the constant high CPU usage by the compositor when mpv is paused
and the window is in view.
According to MSDN, in WM_SYSCOMMAND messages, the four low-order
bits of the wParam parameter are used internally by the system.
To obtain the correct result when testing the value of wParam,
an application must combine the value 0xFFF0 with the wParam
value by using the bitwise AND operator.
This is actually a pretty important fix. eglChooseConfig() might be the
first thing that fails when porobing for desktop GL / ES2 / ES3 support,
because EGL_RENDERABLE_TYPE is set values specific to the underlying
APIs.
Not sure how the hell this worked before. EGL 1.4 implementations
certainly could fail the call with EGL_BAD_ATTRIBUTE if
EGL_RENDERABLE_TYPE has EGL_OPENGL_ES3_BIT set. It's quite possible that
many EGL implementations tolerate invalid EGLConfig values steming from
uininitialized EGLConfig values (and eglCreateWindowSurface() even is
specified to return EGL_BAD_CONFIG error code for "not valid"
EGLConfigs).
The way it should (probably) work is that selecting a RGBA framebuffer
format will simply make the compositor use the alpha. It works this way
on Wayland. On X11, this is... not done. Instead, both GLX and EGL
report two FB configs, which are exactly the same, except for the
platform-specific visual. Only the latter (non-default) points to a
visual that actually has alpha. So you can't make the pure GLX and EGL
APIs select alpha mode, and you have to override manually.
Or in other words, alpha was hacked violently into X11, in a way that
doesn't really make sense for the sake of compatibility, and forces API
users to wade through metaphorical cow shit to deal with it.
To be fair, some other platforms actually also require you to enable
alpha explicitly (rather than looking at the framebuffer type), but they
skip the metaphorical cow shit step.
So that the EGL code can use it too.
Also print the actual FB config ID, instead of nonsense. (I _think_ once
in the past a certain GLX implementation just used numeric config IDs
casted to EGLConfig - or at least that would explain this nonsense.)
Preparation for the following commits. Since at least theoretically the
config selection depends on the context type (EGL_RENDERABLE_TYPE has
separate bits for ES 2, ES 3, and desktop GL), doing it any other way
would be too painful.
For X11 garbage we have to pass some annoying parameters to EGL context
creation. Add some sort of extensible API, so that adding a new
parameter doesn't break all callers. We still want to keep it as a
single function, because it's so nice isolating all the EGL nonsense API
boilerplate like this. (Did I mention yet that X11 and EGL are garbage?)
Also somewhat simplifies the vo_flags mess in the helper internals.
The chroma alignment renormalization code forgot to account for the fact
that the chroma subsampling ratio has to be rotated.
Unfortunately, doing it this way seems to have somewhat broken the
chroma offset rotation logic for odd-sized subsampled image files. While
this is a bug, it's much, much less noticeable, so it's not nearly as
important as the bug this change fixes. Either way, a future patch needs
to still revise this logic, ideally by redesigning the entire rotation
mechanism.

According to MSDN, GetWindowLong and SetWindowLong have been
superseded by GetWindowLongPtr and SetWindowLongPtr.
It's a cosmetic code change in this case.
Apparently we don't always set the viewport to window dimensions
anymore, e.g. if nothing is actually rendered. This means the viewport
can contain old values.
The window screenshot code uses the viewport values to guess the default
framebuffer dimensions. With --force-window --idle --no-osc (which draws
nothing and issues a glClear() command only), taking a screenshot would
yield an image with the wrong size and possibly garbage in it. Fix this
by explicitly passing the currently known window dimensions. Abusing the
values stored in the viewport was questionable anyway.
