- Update libplacebo to version 4.157.0:
This is a major new release involving a significant overhaul of the
public API, full thread safety, support for Direct3D 11 / Win32 /
MSVC, native HDR output, and more.
The primary way of accessing most libplacebo objects has been revamped.
Rather than writing e.g. `const struct pl_tex *image`, users now simply
write `pl_tex image`. In addition, the `struct pl_context *ctx` was
universally refactored and replaced by `pl_log log`, with no concern
besides logging.
Direct3D 11 is now natively supported by libplacebo, and compiling on
Windows in general has been made more straightforward.
The entire API was revamped to be thread safe by default, even when
using OpenGL (assuming the user provides the appropriate context binding
callbacks). Accompanying this change, the `pl_queue` has been rewritten
with multi-threaded decoding loops in mind. See the accompanying
`plplay` demo for an illustration.
Finally, this release brings with it a lot of features for feature
parity with mpv, such as the ability to get pass stats / timings,
oversample scaling, and more.
Additions:
- add a `void *user_data` field to `pl_frame`, with no further
interpretation by libplacebo
- add `pl_queue_push_block`, useful for multi-threaded decoding loops
- add a `uint64_t timeout` to `pl_queue_update`, allowing it to
block until frames are available even when not using a `get_frame`
callback
- make `pl_queue_update` also return valid data when failing with
PL_QUEUE_MORE, allowing access to partial/incomplete mix outputs
- allow calling `pl_render_image` on `image == NULL`, to render overlays
only
- add `pl_get_buffer2`, API-compatible with AVCodecContext.get_buffer2
- add support for blitting from/to several obscure formats such as
a1rgb5 or 64-bit integer formats
- add `pl_tex_clear_ex` to support clearing integer textures
- add `pl_render_params.ignore_icc_profiles`, for debugging
- add `pl_queue_params.interpolation_threshold`, to allow disabling
frame mixing when the source FPS approximately matches the display FPS
- always accept DRM_FORMAT_MOD_INVALID for texture imports
- add extra windowing functions to <libplacebo/filters.h>
- add the `pl_fmt.gatherable` capability
- add `pl_shader_sample_oversample`, a variant of nearest-neighbour
that preserves pixel aspect ratios - good for pixel art
- add `pl_scale_filters` alongside `pl_frame_mixers`
- add support for compile-time specialization constants (`pl_constant`),
and use them to speed up recompilation of shaders with hard-coded
constants
- add `pl_render_params.dynamic_constants`, which lifts hard-coded
constants to dynamic variables - useful for scenarios in which render
parameters are expected to change very frequently
- add more PL_COLOR_TRC_GAMMAxx definitions
- implement full black point adaptation, even when not using ICC
profiles, and infer this black-point-adapted BT.1886 instead of gamma
2.2 as the default gamma curve for SDR files.
- add `pl_shader_res.description` and `pl_shader_res.steps`, containing
more friendly names for shaders plus a detailed list of operations
that shader is performing
- add callbacks to `pl_dispatch` and `pl_renderer` for informing users
of executed passes and their execution times
- add support for the Direct3D 11 graphics API
- add `pl_swapchain_colorspace_hint`, replacing
`pl_swapchain_hdr_metadata` as the new way to update swapchain
colorspace metadata at runtime. This can be used to e.g. switch
between HDR and SDR mode, for supported swapchains
- add `pl_peak_detect_params.minimum_peak`, allowing users to constrain
the detected peak values to only be sensible (e.g. above 1.0)
Changes:
- simplify the `shaderc` pkg-config check - rather than querying for
`shaderc_shared.pc`, `shaderc_combined.pc` etc, simply check for
`shaderc.pc`, matching upstream
- make almost everything thread-safe, and document the parts that
aren't. In particular, almost all GPU state access is now thread safe,
freeing up users to access `pl_gpu` instances from multiple threads,
even when the underlying API is OpenGL
- deprecate `disable_overlay_sampling`, now effectively always true
- `struct pl_overlay` has been refactored completely to allow for
overlays with more than one part per texture. The only way of using
this struct is deprecated
- prefix `enum pl_queue_status` members by `PL_`, fixing an oversight in
the previous version of this API
- make `pl_renderer` automatically clear the target image, freeing users
from the responsibility of calling `pl_frame_clear` themselves. This
can be controlled via three new fields in `pl_render_params`:
`background_color`, `background_transparency` and `skip_target_clearing`
- rename `pl_context` to `pl_log`, and make its use optional. The old
names have been deprecated. It now lives inside <libplacebo/log.h>
- add `typedefs` to all public-facing object types, o make them shorter
to reference. For example, `const struct pl_tex *tex` is now simply
`pl_tex tex`. This change affects almost every type of object in
libplacebo. The old way of referencing these objects is still
possible, but considered deprecated. Note that due to C++-specific
reasons, C++ users *must* upgrade their codeto the new API style
- remove PL_PRIM_TRIANGLE_FAN
- remove support for 64-bit float formats, which probably don't work on
any Vulkan implementation
- stop contrast-limiting ICC profiles, instead assuming perceptual
profiles have infinite contrast
- remove `pl_shader_signature` for being necessarily unsafe
- require Vulkan 1.1 as the minimum vulkan version
- rename `pl_oversample_frame_mixer` to `pl_filter_oversample`, and
allow using it for image scaling as well
- change `pl_color_space_monitor` from PL_COLOR_TRC_GAMMA22 to UNKNOWN
- change the signature of `pl_shader_(de)linearize` slightly
- significantly increase the default strengths of the desaturation
settings in`pl_color_map_params`, to mimic the hollywood feel
- refactor `pl_glsl_desc` and `pl_gpu_caps` completely, in favor of the
new structs `pl_glsl_version` and `pl_gpu_limits`, with new members.
The old API is still available for the time being, but deprecated

* Fri Apr 02 2021 Niklas Haas <obs@haasn.xyz>
- Update libplacebo to version 3.120.0. (Upstream changelog appended)
- Create a new package `plplay` for the included demo program. This requires
bundling a copy of `nuklear.h`, which is single-header library not included
as part of the libplacebo source distribution.
This is a feature release, introducing frame mixing, DRM format
modifiers, and support for custom LUTs -, while also greatly expanding
the available demo programs, in particular the `plplay` video player.
The main highlight is the new `pl_queue` abstraction living in
<libplacebo/utils/frame_queue.h>. This greatly simplifies the core of a
libplacebo-based video renderer by translating a stream of input frames
into an array of GPU-mapped textures suitable for frame mixing, given a
corresponding vsync timestamp. New frames can be delivered to this API
using a push or pull model, and they are lazily uploaded on an as-needed
basis as well as internally garbage collected when no longer needed.
This abstraction also contains all needed machinery for estimating
source/display framerates by comparing and averaging timestamps, freeing
users from the burden of having to accurately determine this information
a priori.
Also worth mentioning is the addition of support for custom LUTs,
currently only in Adobe's .cube format. They can be applied flexibly at
a number of locations in the video processing pipeline, including as a
replacement for YUV<->RGB conversion or tone/gamut mapping, and fed with
either normalized linear light or native-gamma values.
Among the included demo programs, the `plplay` example video player has
been greatly expanded - adding support for a settings GUI (based on
nuklear), frame timing and mixing, custom shaders, and more. This
example video player now serves as a convenient platform to demonstrate
all of libplacebo's advanced rendering features.
Finally, all of libplacebo now contains only code written entirely from
scratch (rather than deriving from mpv), opening up the possibility to
explore different licenses besides the current LGPLv2.1+. In particular,
permissive (MIT/BSD-style) licenses are being considered.
Additions:
- add asynchronous GPU callbacks, specifically to `pl_tex_transfer`,
allowing for non-blocking host memory transfer operations

indexed vertex data when dispatching shader passes
- add `pl_dispatch_vertex` to allow dispatching fragment shaders using
a list of custom vertices with custom vertex attributes

apply white point adjustments between correlated color temperatures (K)

name for a given filter preset
Changes:
- `pl_3dlut_params` has been renamed `pl_icc_params`
- `pl_render_params.force_3dlut` has been renamed `force_icc_lut`
- `pl_3dlut_update/apply` have been renamed to `pl_icc_update/apply` and
moved to a (conditionally installed) new header <libplacebo/shaders/icc.h>
- `pl_upload_plane` no longer initializes `out_plane->shift_x/y` to 0,
instead leaving them unmodified (to avoid clobbering existing shift data)
- `pl_filter_box` has been renamed to `pl_filter_nearest`
- `pl_filter_triangle` has been renamed to `pl_filter_bilinear`
- `pl_render_params.frame_mixer = NULL` now disables frame mixing - to
get back the old behaviour, set this to `&pl_oversample_frame_mixer`.
- `pl_color_map_params.gamut_warning` now highlights out-of-gamut colors
in bright pink, rather than the old (ill-defined) inversion behaviour
- `pl_named_filter_config` has been renamed to `pl_filter_preset`
- `pl_find_named_filter` has been renamed to `pl_find_filter_preset`
- ditto for `pl_named_filter_function` and `pl_filter_function_preset`

* Fri Jan 01 2021 Mia Herkt <mia@0x0.st>
- Update to version 3.104.0
This is a major release, introducing many new features and
modifications. Most importantly, libplacebo now interoperates well
with FFmpeg's libav* abstractions. This is primarily exposed via a
new set of helpers, <libplacebo/utils/libav.h>, implemented as a
single header library. In addition to this, a number of other
supporting changes have been made to the API, most notably the
unification of `pl_image` and `pl_render_target` into a single
`pl_frame` concept, similar in spirit to AVFrame. As such,
libplacebo now supports **rendering to planar targets**, including
subsampled YCbCr.
Besides the libav* compatibility changes, this release also brings
with it a new feature for custom shaders: buffer blocks, and
persistent storage. This can be used by third parties to implement
stateful shaders (e.g. motion interpolation or temporal
deinterlacing), or be leveraged to speed up some shaders by
combining multiple passes into one.
Finally, various import/export procedures have been expanded,
including the ability to import host pointers and real-world
DMABUFs.
Additions:
* add `pl_memory_qualifiers`, plus a corresponding
`pl_shader_desc.memory`, to allow attaching GLSL memory
qualifiers (coherent, volatile etc.) to shader descriptors
* add functions `pl_dispatch_save` and `pl_dispatch_load` to
allow saving/restoring the contents of an entire
`pl_dispatch`'s cache
* add functions `pl_renderer_save` and `pl_renderer_load` to
allow saving/restoring the contents of an entire
`pl_renderer`'s cache
* add `pl_vulkan_swapchain_params.prefer_hdr`, which will cause
the surface format selection logic to try HDR output formats
first
* add `pl_buf_copy` to copy from one buffer to another
* add `pl_get_detected_peak`, to read back the result of peak
detection
* add `pl_primaries_superset` to test if one set of primaries is
fully enclosed by another
* add `pl_color_map_params.gamut_clipping`, which will
colorimetrically clip any out-of-gamut colors by desaturating
them towards neutral gray until they're in-gamut, rather than
clipping per channel as before
* add `PL_GPU_CAP_SUBGROUPS` and `pl_gpu_limits.subgroup_size`,
to expose GLSL subgroup functionality via the `pl_gpu`
interface
* add `pl_gpu_is_failed`, to query at a high level whether the
`pl_gpu` is in some internal failure state. GPUs in this state
should be recreated, using the appropriate mechanism
* add `pl_shader_custom`, to allow injecting arbitrary custom
GLSL code into a `pl_shader`.
* add `pl_buf_params.import_handle` to allow importing buffers
* add `PL_HANDLE_HOST_POTR`, to allow importing arbitrary host
pointers
* add `pl_pass_run_params.vertex_buf`, to allow drawing vertex
data directly from a `pl_buf`, guarded by
`pl_gpu_limits.max_vbo_size`
* add `_COUNT` members to all public enums, for consistency
* add `pl_shared_mem.drm_format_mod`, to allow communicating
DRM format modifiers when importing/exporting textures
* add support for importing DMABUFs via EGL, via the new fields
`pl_opengl_params.egl_display/context`
* add `pl_fmt.fourcc` to facilitate mapping between `pl_fmt` and
DRM
* add the missing `pl_var_*` helpers, for consistency
* add `pl_plane_data_align` to help with aligning
`pl_plane_data` structs to byte boundaries
* add support for STORAGE textures in user shaders, which can be
used to persist data across separate invocations of the shader
* add support for BUFFER blocks in user shaders, which can be
used to create UBOs or SSBOs for use inside shaders, the latter
of which can also persist across frames and be used to store
persistent state
* add PL_COLOR_PRIM_EBU_3213 and PL_COLOR_PRIM_FILM_C
* add a new header <libplacebo/utils/libav.h>, containing a
variety of helper functions for interoperating between libav*
and libplacebo
* add `demos/plplay.c` to serve as a demonstration of how to make
a trivial playback loop with libavcodec and libplacebo
* add `pl_sample_src.component_mask` to allow sampling an
arbitrary subset of the available components from a plane
* add `pl_frame_is_cropped` and `pl_frame_clear` to assist in
properly clearing frames before rendering to them
* add `pl_tex_poll` to assist in interoperating with some
external APIs
* add `pl_render_params.blend_params` to allow blending the final
output
Changes:
* remove `pl_image.signature` and
`pl_render_params.skip_redraw_caching`
* change vulkan surface format selection to prioritize formats by
'score', preferring higher depth integer formats
* `pl_fmt` may now have PL_FMT_CAP_STORABLE even when
`glsl_format` is NULL, in which case formatless image storage
must be used
* `pl_buf_read` no longer requires `buf_offset` be a multiple of
4
* `pl_buf_*` commands are now synchronized internally:
* `pl_buf_write` and `pl_buf_read` now block while the buffer is
in use Note: for this reason, `pl_buf_write` should not be used
in loops
* `pl_tex_upload/download` may now be called on in-use buffers
* allow `pl_dispatch_compute` on shaders with outputs, including
the ability to automatically determine the number of work
groups based on the shader output resolution
* remove `pl_buf_params.type`, and the concept of buffer types in
general. `pl_buf` is now a generic catch-all for any type of
buffer, with individual capabilities in `pl_buf_params`
determinig what type of shader operations it can be used for
* relax the alignment requirements on `pl_tex_transfer_params`
* change `pl_opengl_wrap_params` to allow directly importing
framebuffers in addition to textures
* rename `pl_color_levels` members for clarity
* make `pl_opengl` ignore software rasterizers by default, unless
the new field `pl_opengl_params.allow_software` is set
* add `pl_av1_grain_params.luma_comp` to allow drawing the luma
component from a channel with nonzero index
* `pl_renderer` now supports rendering to planar targets,
including subsampled targets
* `pl_image` and `pl_render_target` have been removed and unified
into a single `pl_frame` concept
* remove `pl_tex_params.sample_mode/address_mode` and move them
to `pl_desc_binding` instead, to decouple them from texture
creation
* refactor the signature of `pl_tex_blit`
Fixes and performance improvements:
* fix an oversight where `pl_buf_destroy` delayed some buffer
destructions unnecessarily
* fix a limitation where `pl_tex_destroy` sometimes delayed
destroying textures unnecessarily
* improve the performance of `pl_dispatch`'s code for assembling
UBOs
* improve the performance of `pl_shader_av1_grain` by switching
from SSBOs to texture LUTs, also improving compatibility with
older GL
* improve the performance of `pl_shader_detect_peak` on GPUs with
access to subgroups operations
* fix an issue where reinitializing shader state objects with
different settings sometimes resulted in undefined behaviour
* fix some GLSL backwards compatibility issues
* slightly cut down on unnecessary image layout transitions
* add some miscellaneous debug print-outs, and improve the
legibility of some existing log messages
* fix an issue where freeing buffer variables from shader
descriptors could result in use-after-free
* add support for vulkan memory imports requiring dedication
allocations
* slightly improve, and fix, the vulkan memory placement logic
* significantly improve the performance of `pl_tex_download` by
importing the target host pointer directly
* improve the performance of small LUTs, especially for the
non-compute polar fallback path
* prevent `pl_renderer` from unneccessarily applying a 3DLUT when
both the input and output frames have the same ICC profile
* fix the behaviour of partially specified `pl_bit_encoding`
structs
* fix the component ordering on some odd packed vulkan formats
* fix an issue where `pl_plane_data_from_mask` broke for high bit
depths
* make `pl_renderer` consult the dither bit depth from the
texture precision, if absent from `pl_bit_encoding`
* fix the behaviour of `pl_renderer` when sampling from textures
with swapped component orders
* fix the implementation of PL_COLOR_SYSTEM_BT_2100_HLG
* fix some issues relating to missing includes
* enforce legality of image usage parameters on `pl_vulkan_wrap`
* fix an undesired shader double-compilation when using
orthogonal scalers with subsampled chroma planes
* fix an issue where application of a 3DLUT cleared the alpha
channel
* add a missing extension to `pl_vulkan_recommended_extensions`
* fix the plane alignment code for oddly sized subsampled chroma
* fix the poor precision of `pl_shader_dither` for high bit
depths
* fix several possible overflows in the BT.2390 shader
* fix a bug where using a polar sampler to draw a scaled overlay
onto a non-storable target neglected to disable compute shaders
* fix a bug where the renderer could sometimes alias when
downscaling, in particular if both the upsampler and
downsampler are set to bicubic
* improve performance of scalers by avoiding bilinear filtering
* reduce verbosity of memory allocations
* fix missing PL_FMT_CAP_BLENDABLE on opengl fbos
* significantly improve precision of float literals in shaders
* add better error checking to gl_pass_create
