Another modification for the upcoming meson build. Meson can capture the
stdout and redirect it to a file. However, this is considered a hack.
It's better to just add a few lines to this script and write a file
directly.
Apple is great and forces us to do a lot of weird checks because they
randomly move the location of the swift libraries around. Make a
specific python script for checking various locations and write the
output to stdout for meson.
Building for macos requires us to check the macos sdk path as well as
the sdk version that is on the system. To do this, let's steal the logic
that's in the compiler_swift.py check from the waf build. This returns a
comma-delinated string. The first entry is the absolute path to the sdk.
The second entry is the detected macos sdk version.
version.h is essential for building, and its generation was done by a
shell script. Strictly speaking, python should in general be more
portable (windows), and would be better for the upcoming meson build to
simply just execute a python script. version.py has some small
differences with version.sh which shouldn't matter but they are noted
below.
- version.sh accepted several arguments that seemed useless (like
--cwd). These were removed from version.py.
- version.py takes either no arguments (prints the version) or it takes
exactly one argument specifying the complete path of where the header
should be generated.
- version.sh attempted to read a file named "snapshot_version". The
comments noted that this was for "daily tarball snapshots". Such a
file does not exist in the source tree, and it's not really clear that
anyone actually uses this. This logic was removed from version.py.
- version.py reads the SOURCE_DATE_EPOCH environment variable. Some
distros use this for reproducible builds. Technically you could also
just disable the build date but this is only a couple of extra lines
and maybe it's prettier than UNKNOWN.
- version.py also doesn't attempt to display timezone information in the
build date. It only shows UTC time.
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.
The new GBM supporting nvidia drivers declare support for 10bit
surfaces using BGR ordering, rather than RGB, so add support for them.
We've also seen examples of hardware supporting BGR8888 but not
RGB8888 so let's support those too.
Of course, the nvidia EGL driver doesn't publish support for any 10bit
formats so you can't actually do 10bit display. Perhaps they'll
eventually fix that.
The GBM supporting nvidia driver doesn't support creating surfaces
without modifiers and using modifiers is more and more recommended as
the right way to do this.
Enumerating modifiers is painfully verbose, but necessary if we are to
allow the driver to pick the best possible one.
This fixes a mismatch between configure working and build time
failing with Linux + OSSv4, enabling compilation on Debian based
Linux systems with the oss4-dev package.
Fixes#9378
This logic, which was working around a libplacebo bug, ended up always
alpha blending - even for sources without an alpha channel. This caused
a minor slowdown to be constantly enabled.
Due to the recent bump to libplacebo v170, this is no longer needed.
Completely untested, since Linux still can't into HDR in 2021. Somebody
please make sure it works.
Technically covers #8219, since gpu-context=drm can be combined with
vo=gpu-next.
This required an upstream API change to implement in a way that doesn't
unnecessarily re-push or upload frames that won't be used. I consider
this a big enough bug to justify bumping the minimum version for it.
Closes#9401
This was originally added in f2afae55e9
for unclear reasons (way to go me). This concept is clearly incorrect.
It doesn't matter what state the window is in. As soon as mpv detects a
scale change, it needs to reset the buffer scale of the window. Just
remove all this junk and put wl_surface_set_buffer_scale in
set_surface_scaling like it should be. Related issue: #9426.
Looking at this again I'm not sure it does anything useful at all. The
man page entry is also wrong: `bicubic` is not affected, only
`bicubic_fast`, and those filters are not configurable anyways.
So this would only ever be a debugging option, and I don't see a
pressing need for it.
No interface-change.rst update because it only just got added anyways.
In practice, this is for wayland. vo_gpu_next doesn't check the
check_visible parameter since it didn't descend into the
vulkan/context.c file when starting a frame. To make this happen, just
call the start_frame function pointer but pass NULL as the ra_fbo. In
there, we can do the visibility checks and after that bail out of the
start_frame function if ra_fbo is NULL.
This vulkan-specific parameter was poorly named and probably causes
confusion. Just rename it to check_visible instead to make clear what is
going on here. Only wayland uses it for now but in theory anyone else
can. As an aside, wayland egl accomplishes this by using an external
swapchain instead (an opengl-only concept in the mpv code). This may or
may not need to be changed in the future when gpu-next gets opengl
support.
As discussed in #8799, this will eventually replace vo_gpu. However, it
is not yet complete. Currently missing:
- OpenGL contexts
- hardware decoding
- blend-subtitles=video
- VOCTRL_SCREENSHOT
However, it's usable enough to cover most use cases, and as such is
enough to start getting in some crucial testing.
This seems to work on gcc, clang and mingw as-is, but I made it
conditional on __GNUC__ just in case, even though I can't figure out
which compilers we care about that don't export this define.
Also replace all instances of assert(0) in the code by MP_UNREACHABLE(),
which is a strict improvement.
A lot of people seem to do something like --tscale=box
--tscale-window=<function>. Just let them use --tscale=<function>
directly, by also accepting raw windows.
Kinda hacky but needed for feature parity with vo_gpu_next, which no
longer has `--tscale=box`. Note that because the option struct is still
shared, vo_gpu_next inherits the same option handling code, so we have
to export this feature for vo_gpu as well.
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.
The problem with the previous code - which used mp.get_user_path, is
that it returns a path even with --no-config, and even if the file
doesn't exist.
This is why we tested the "config" property, and also used
mp.utils.file_info to check that the file exists.
mp.find_config_file doesn't return a path with no-cofig and doesn't
return a path if the file doesn't exists. It's simpler and better.
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.
The bytes_read struct member in AVIOContext is now officially public,
so its usage no longer has to be specified as non-compliance with
FFmpeg's ABI/API rules.
That said, unfortunately there was a short period of time between
August 2021 and October 2021 where the struct member did not exist
in FFmpeg's git master, so keep a feature check for it alive for
now to enable building with those versions. Thankfully, no release
version of FFmpeg will be without this field, so it should be
possible to drop this check with time.
Finally, simplify the function in case the struct member is not
found. After all, there is zero reason to iterate through the AVIO
contexts if we cannot get the information we require.
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.
