This library contains GPU-accelerated video/image rendering
primitives, as well as a standalone vulkan-based image/video
renderer. It is based on the core rendering algorithms and ideas
of mpv.

Changelog

2019-02-26 - Martin Herkt <9+suse@cirno.systems>
- Build with (preferred) shaderc now that it?s packaged in TW
- Update to version 1.18.0
The major changes of this release include a new and completely
overhauled HDR tone mapping algorithm, support for importing
backing memory for textures and buffers (such as via dmabuf fds),
as well as a swapchain resizing API that, among other benefits,
allows libplacebo to function properly on Wayland.
There is also now support for generating CPU-backed "dummy
resources" for things like lookup tables or convolution kernels,
for users who prefer managing their own GPU resources.
This allows pl_shader-level API users to access the full host of
libplacebo shaders without being restricted the lack of a pl_gpu.
Additions:
* pl_color_space now has a sig_scale field, which allows
modifying the signal range without affecting the transfer
function's shape. (Effectively, by "stretching" it).
This can be useful when dealing with HDR material encoded in a
non-HDR curve such as linear light.
* Add support for importing handles (including pl_sync objects
and pl_shared_mem). Currently, only memory can be imported.
* Add partial support for dmabuf fd interop. Currently does not
support dma layout modifiers, so the usefulness of this feature
is limited.
* Allow importing external memory when creating textures.
* Add a way to overexpose HDR material to bring its brightness up
to more easily viewable levels.
* Add pl_var_int to go alongside the other gpu.h helpers.
* Add a way to create CPU-backed "dummy" instances of pl_gpu.
These are not capable of compiling or executing any shaders,
so they're only useful for users who want to generate and
compile their own shaders.
All GPU resources (textures, buffers) are backed by malloc.
* Add a new field to pl_tex/buf_params allowing users to attach
arbitrary references (void*) that libplacebo will ignore.
* Add a function for changing the pl_context_params after
creation.
* Add a new API function for dealing with swapchain resize
events. This function can be used to both query and update
the swapchain size, based on the usage.
Not all platforms support all operations.
* Add new demo/skeleton based on GLFW.
Changes:
* Remove the hdr_simulation field from pl_color_map_params.
Use signal_scale on the target color space instead.
* Subdivide handle capabilities based on object type
(texture vs buffer).
* Completely redesign the HDR tone mapping algorithm.
Most members of pl_tone_mapping_params have been updated,
in particular the options related to desaturation and peak
detection.
* Split up the HDR peak detection API into a "detection" and
"application" stage, which can run independently. This avoids
the one-frame delay inherent with the previous API, and thus
allows tone mapping to be frame perfect.
* Remove superfluous field from pl_shader_reset left behind
from a previous version of the API.
Fixes and performance improvements:
* Correctly apply the OOTF before performing linear colorspace
operations on scene-referred content.
* Avoid clipping when tone-mapping out of gamut content by tone
mapping before gamut mapping.
* Correctly reset the peak detection buffer state when running
pl_renderer_flush_cache.
* Correctly use the image's original color space as the reference
space when the content is prelinearized by the renderer.
Fixes some cases where libplacebo could end up defaulting
PL_COLOR_TRC_AUTO to a suboptimal curve.
* Correctly track the lifetime and ownership of individual vulkan
buffer objects. Fixes some synchronization issues when
attempting to use the same buffer from multiple different
queue families.
* Fix integer overflow on implementations with very large
texture size limits.
* Fix building against static libshaderc.
