- Don't define _GNU_SOURCE on Windows, no need
- Define WIN32_LEAN_AND_MEAN to strip some unneded headers from
windows.h
- Define NOMINMAX and _USE_MATH_DEFINES as they are common for Windows
headers
We prefer to fail fast rather than degrade in unpredictable ways.
The example in sub/ is particularly egregious because the code just
skips the work it's meant to do when an allocation fails.
This property was never encouraged. The manual even stated that "You
should avoid using it, unless you absolutely have to." Since we now have
user-data which is superior in every single way and replaces this,
delete this property. The manual also has threatened people for years
with the line "It's a makeshift solution which could go away any time
(for example, when a better solution becomes available)." We were nice
and deprecated it in 1d00aee8e1 for a
while to give script authors some time to update. Let's remove it for
good now.
This mostly is added to resolve player command synchronization with VO
thread discussed in 477a0f83.
The current uses does not necessarily need this as they are all managed
by playloop. But for future use with other params that will be handy.
Those params are mostly to observe current state of VO and does not
necessarly need to be locked along with frame drawing, that changes the
params once at the end.
Only vaapi-copy variant as nothing can map D3D12 resources currently.
And even if we would add resource sharing to D3D11 it would invoke copy
at some point, so there is no point really. Maybe in the future when
libplacebo get smarter about resource sharing on Windows, but practical
advantages are really small. I've tested it with Vulkan <-> D3D11
sharing and GPU <-> GPU copy is still invoked. Better than CPU memcpy,
something for the future.
Up to 2x playback rate is the most we can offer currently. Should work
fine for most kernels with radius <= 2.
This avoids limitation of hwdecs number of frames in-flight.

there is 1px border at the top of the window that is not covered by our
title bar and the video below is visible. this broke in some newer macOS
version even so the calculation of size and position of the title bar is
still correct. add 1px the the height of the title bar to cover up the
unwanted border.
Unclear if there are other situations but at least using --force-media-title
this can be called without a playing file, causing a segfault.

The "auto" logic is vastly better than setting a specific size. This
option amounts to "allow users to shoot themselves in the foot" flag,
given that the vast majority of ICC profiles in the wild are fine on
17x17x17 or even smaller 3DLUTs.
Setting stupidly high --3dlut-size is the main source of ICC-related
slow startup issues, and there is absolutely no conceivably benefit to
going above the defaults except for pixel peeping and chasing tiny PSNR
increments.
These are less likely to be modified from run to run, and with the
avoidance of redundant re-saving we can get away with a larger size.
This is enough to save 10 3DLUTs at typical sizes.
D3D11 is actually the main platform that suffers from slow shader
compilation, typical Vulkan/GL drivers are either very fast to begin
with, or already internally cache.
I have no idea why this code is such a convoluted mess of options and
possibilities. First of all, why is dumping both caches to a single file
even a supported use case? Why is the cache path generated multiple
times, once for saving and once for loading, instead of just generated
once and stored? Why even create a pl_cache if you're not going to
save/load it? Why so much code duplication?
I don't know. But I rewrote it in a way that makes far more sense to me.
This change prevents unwanted adjustments. Generally, screenshots
shouldn't invoke pl_queue_update, as this action could cull the already
mapped frames in the queue.
If !display_synced, some values may not be correct or zeroed. Therefore,
it makes no sense to interpolate in this case.
For a non-moving frame, we always want to show an uninterpolated frame.
libplacebo requires additional frames when VPS is lower than FPS and
anti-aliasing is enabled. Supports up to a 1/4 ratio. VO has a limit of
10 frames, so in practice, not many more can fit.
Note that the internal libplacebo mixing limit is 16 frames.
The `current_frame` can be redrawn even if the remaining `num_vsync` is
equal to 0. In this scenario, the vsync offset would be incremented
beyond the target point.
