LGPL-2.1-or-later
* Wed May 06 2020 Mia Herkt <mia@0x0.st>
- Update to version 2.43.1
This release backports a number of bug fixes from master affecting
the v2.43.0 release, and also slightly extends the range of
backwards compatibility with respect to vulkan-headers versions.
(This change is not on master, so this can be seen as a
compatibility release)
Bug fixes:
* fix GLSL version checks when overriding GLSL versions with
pl_shader_params.glsl
* fix minor order-of-operations issue in AV1 grain synthesis
* fix glInvalidate* backwards compatibility issue
* fix compilation with older vulkan-headers (e.g. ubuntu 18.04)
* fix a bug where pl_shader_encode_color sometimes uploaded and
applied an identity matrix unnecessarily
* work around upstream issues with MSL shader compilation by
ensuring all buffer elements are sorted by offset
* fix hypothetical edge case with swapchain image usages
forbidden by the swapchain image format
* fix an issue where blending overlays caused the rest of the
image to be discarded
Other changes:
* log the vulkan surface selection choices
* log the overall library version on initialization
* add a few more pl_gpu validation checks
* significantly reduce the CPU consumpation of blocking texture
downloads
* Thu Apr 23 2020 Mia Herkt <mia@0x0.st>
- Add libepoxy to BuildRequires
- Enable test suite
- Update to version 2.43.0
The major highlight of this release is the introduction of a new
OpenGL backend, documented in <libplacebo/opengl.h>, which is also
the reason for the major version bump.
Apart from the addition of OpenGL support, this release brings with
it a large number of fixes for backwards compatibility with older
versions of GLSL and GLES, allowing libplacebo to be used to
generate legal shaders for virtually any GLSL version in existence.
Supporting these changes, the test framework has been expanded
considerably to allow for automated testing of older OpenGL context
versions and older GLSL versions.
Additions:
* add pl_gpu.pci, containing the PCI address of the underlying
GPU
* add pl_image.av1_grain, allowing pl_renderer to add AV1 grain
* add pl_opengl backend (see <libplacebo/opengl.h>)
* add pl_color_levels_guess, to infer color levels from
pl_color_repr
* pl_shader_encode_color now handles non-linear color systems
* add pl_render_params.force_dither, to force use of the dither
code
* add pl_render_params.disable_fbos, to forcibly disable FBOs
* add pl_vk_inst_params.layers, to allow loading extra vulkan
layers
* add a way to restrict the maximum GLSL version provided by the
various pl_gpu backends, for testing purposes
Changes:
* load all vulkan function pointers indirectly, using a
user-provided vkGetInstanceProcAddr function
* vulkan can now be built without linking against libvulkan.so
* refactor av1 grain data struct, splitting it up into
"grain metadata" and "shader params"
* pl_swapchain_resize now recreates suboptimal swapchains even
if the size does not change
* pl_tex_blit now requires the new cap PL_GPU_CAP_BLITTABLE_1D_3D
for 1D/3D textures
* pl_tex_params.host_readable now requires the new cap
PL_FMT_CAP_HOST_READABLE on the chosen format
* pl_vk_inst_create will now automatically load any layers needed
for extensions specified by the user
Fixes and performance improvements:
* make pl_color_adjustment.gamma actually do something
* fix av1 grain shader for separated planes
* fix memory corruption in pl_vulkan_swapchain_suboptimal
* fix access mask on API writes to read-writable vulkan buffers
* fix some instances of undefined behavior in av1 grain synthesis
* fix av1 grain scale for PL_COLOR_LEVELS_UNKNOWN
* fix use of local #include for config.h in installed headers
* fix various incorrect literals for compatibility with older
GLSL
* fix potential type error in XYZ input handling
* fix numerous backwards compatibility issues for older GLSL and
GLES versions, across the board
* quench some meson warnings, as well as some compiler warnings
* Tue Dec 24 2019 Martin Herkt <9+suse@cirno.systems>
- Update to version 1.29.1
This is a minor bug fix follow-up, to address one major and two
minor issues with the v1.29.0 release.
Fixes:
* segfault in the test framework on platforms without vulkan
* error message spam when rendering to minimized/hidden windows
* compilation on certain glslang versions
* Mon Dec 23 2019 Martin Herkt <9+suse@cirno.systems>
- Update to version 1.29.0
The key highlights of this release are the change of pl_gpu API
semantics to use explicit erroring instead of implicit undefined
behavior, and several important bug fixes related to swapchain
resizing (in particular, handling of suboptimal swapchains);
as well as other minor utility changes, bug fixes and performance
improvements.
The new pl_gpu API allows clients to duplicate less code related
to checking parameters and capabilities, as long as they're fine
with the resulting error messages they might receive. In
particular, libplacebo no longer aborts on invalid parameters -
which helped during initial development, but is now suffocating
clients more than it's helping.
Additions:
* add a new field pl_fmt.internal_size, which can differ from
texel_size for emulated formats
* add 16f / 64f texture formats with host-emulated 32f
representation
* expose a pl_vulkan_choose_device helper function
* add a mechanism for allowing the user to explicitly resize
suboptimal swapchains rather than having libplacebo take care
of it
Changes:
* make pl_gpu log and error gracefully on illegal parameters
rather than doing undefined behavior (i.e. aborting)
* creating a host_mapped buffer now requires
PL_GPU_CAP_MAPPED_BUFFERS
* drop priv fields from public structs
Fixes and performance improvements:
* make libplacebo slightly less log spammy in general
* skip the creation/use of semaphores for single-queue usage
* fix several bugs related to swapchain recreation and image
acquisition
* fix creation of non-renderable but storable vulkan textures
* fix several bugs related to emulated texture downloads
* fix pl_fmt capabilities for some emulated formats
* fix stride/alignment of std430 vectors/matrices
* use push constants more aggressively, whenever possible
* slightly improve accurate of BT.2100 matrices
* fix overzealous rotation of vulkan queues
* fix dangling validation layer suppression in rare cases
* fix possible swapchain deadlock on VK_SUBOPTIMAL_KHR
* handle VK_SUBOPTIMAL_KHR more gracefully / efficiently
* Mon Oct 21 2019 Martin Herkt <9+suse@cirno.systems>
- Update to version 1.21.0
This is a minor / house-keeping release, mostly to get some
important fixes into distros while also getting support for iGPUs
requiring non-coherent memory into a "stable" release.
Additions:
* shaders.h API users can now override the GLSL version
* add support for vulkan platforms with non-coherent memory
(e.g. iGPUs)
Changes:
* default GLSL version is now 130 unless otherwise specified
* signature of pl_shader_alloc now uses a params struct
* PL_FIX_VER / PL_VERSION are no longer header constants
* the renderer will now automatically adjust deband grain scale
for HDR
Fixes and performance improvements:
* on GLSL < 130, shaders now correctly use texture2D etc.
* fix a bug where async transfer was never actually used, due to
incorrect alignment checks
* fixed some issues that could lead to symbol conflicts
* don't require large vertex buffers be host-visible
(usually impossible)
* correctly detect swapchain image feature flags
* turned a few 1ms busy loops into infinite waits
* fix compilation on some platforms that require SPIRV-Tools
* fix vkCreateEvent error spam on MoltenVK
* bump queued command limit from 64 to 1024
* Tue Feb 26 2019 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.
* Sun Dec 16 2018 Martin Herkt <9+suse@cirno.systems>
- Remove baselibs.conf since nothing needs it
- Fix build due to missing shaderc, which is optional
- Switch to new upstream URL
- Update to version 1.7.0
This release marks the first major release of libplacebo, in tune
with the release of VLC 4, which will be the first major project
using it. Apart from API stability going forwards, this release
brings with it a new AV1 film grain shader, better
interoperability between libplacebo and external APIs like CUDA
(via shared buffers and shared textures), and ICtCp support.
While not strictly part of libplacebo, one of the highlights
since the previous release includes the existence of a new
example file demos/video-filtering.c which illustrates how one
would use libplacebo to do GPU-based image filtering in something
like FFmpeg or mpv.
Additions:
* Add a new function pl_gpu_finish which blocks until all
oustanding rendering on this pl_gpu is finished.
* Add new functions pl_tex_recreate and pl_buf_recreate, which
work like pl_tex/buf_create but take a pointer to an existing
tex/buf that will get destroyed + recreated only when necessary
* Add a new function pl_shader_is_failed which will return true
if a given shader is in a "failed" state. Shaders will be
marked as failed on any internal/usage error, rather than them
being silently ignored.
* Add a new enum pl_channel to clarify and encode friendly names
for the often-referenced "canonical channel order".
* Add a new header libplacebo/shaders/av1.h which currently
contains a function pl_shader_av1_grain for applying AV1 film
grain on the GPU.
* Add a new concept of an "exportable" object (buffers and
textures). Exportable objects can be exported using a handle
and imported into other foreign APIs such as CUDA.
The new functions pl_buf_export and pl_tex_export must be used
to correctly synchronize access to the object. This also adds
new fields uuid and handle_caps to pl_gpu.
* Supporting the previous feature, add a new field memory_type
to pl_buf_params which can be used to influence what type of
memory to allocate a buffer from. Currently only works for
texture transfer buffers, since allocating uniform/storage
buffers from non-VRAM makes little sense.
* Add a new synchronization primitive wrapper, pl_sync, which
wraps a semaphore pair and must be used to synchronize access
to textures with external, asynchronous APIs.
* Implement the ITU-R BT.2100 ICtCp color system. Since the
libplacebo color systems are not strictly tied to any
particular transfer function, we must explicitly mark which
flavor of ICtCp is meant.
* Add a new field instance_params which can be used to influence
the parameters used when pl_vulkan_create ends up creating an
internal instance.
* Add a new function pl_vulkan_unwrap which allows users to
unwrap a vulkan-baed pl_tex to expose the internal VkImage,
allowing simultaneous use (via pl_vulkan_hold/release) similar
to wrapped external images.
* Add new generic helper functions pl_std430_layout and
pl_std140_layout which replace the old pl_buf_uniform_layout,
pl_buf_storage_layout and pl_push_constant_layout.
Changes:
* Empty device names ("") can now be passed to pl_vulkan_create.
They will be treated as if NULL was passed.
* The out_plane parameter of pl_upload_plane is now optional.
* Clarify/Relax the restrictions on pl_buf usage and polling.
Users are technically free to use pl_buf for multiple
simultaneous libplacebo operations. Buffer polling is only
needed for accesses by the host.
* pl_vulkan_hold now returns a bool indicating success.
* pl_buffer_var has been moved from gpu.h's pl_desc to
shaders.h's pl_shader_desc. Describing the individual variables
of a descriptor binding had zero practical application.
* pl_buf_uniform_layout, pl_buf_storage_layout and
pl_push_constant_layout are now macros for pl_std140_layout
and pl_std430_layout (respectively).
This changed the signature to drop the pl_gpu parameter.
* The buf_offset parameter to pl_tex_transfer no longer needs to
be strictly aligned to a multiple of 4. The minimum alignment
is now 1, however users are strongly recommended to stick to
the multiple-of-4 alignment (or ideally align_tex_xfer_offset)
for performance reasons.
* The chromatic adaptation method in pl_get_color_mapping_matrix
has been adjusted. We now use an LMS model derived from
CIECAM97's revised linear Bradford matrix, rather than the
non-linear matrix that was being used previously (incorrectly
so, due to the lack of the required nonlinearity).
* The order of fields in pl_rect3d has been changed for
consistency with the other rect types.
Fixes and performance improvements:
* Fix std140/std430 packing errors for vec3.
* Skip unnecessary flush in pl_buf_poll noop cases.
* Fix variable collision in sh_prng.
* Don't leak glslang internal symbols on supported platforms.
* Fix an issue where pl_pass_run was stricter than intended about
compatibility with between target and target_dummy.
* Fix an issue where pl_dispatch could sometimes try dispatching
shaders with an incompatible target.
* Fix an error in the heuristic for choosing the optimal image
layout for vulkan render passes.
* Improved debugging messages in several places.
* Slightly speed up lookups from texture LUTs.
* Fix the addressing of shader LUTs in some hypothetical cases.
* Correctly flush the contents of host-readable buffers after
modifications made by the GPU.
* Fix synchronization on pl_buf_write with non-mapped buffers.
* Fix undefined behavior when using push descriptors.
* Slightly speed up some texture recreate operations by
invalidating re-used textures.
* Fix an issue when trying to update large (>64k) VRAM-resident
buffers.
* Fix two address calculation bugs in pl_tex_blit.
* Fix an over-read bug when the size of the vertex data changed
for otherwise identical passes.
* Fix a misalignment that could theoretically happen with some
combinations of (odd) texel sizes and device alignment
requirements.
* Fix UB when creating "useless" images (without any usage flags)
* Fix a vulkan device memory leak when destroying large textures.
* Fix an alignment issue that could happen sometimes with
pl_buf_write for odd write sizes.
* Fix an alignment bug when uploading partial textures when async
transfer is enabled on some devices.
* Fix crash in pl_color_primaries_is_wide_gamut on DISPLAY_P3.
* Fix an error when re-using shader objects between polar and
non-polar samplers. This is now safe to do.
* Fri Sep 28 2018 Martin Herkt <9+suse@cirno.systems>
- Add C/C++ compilers, glslang and lcms2 to BuildRequires
- Update to version 0.6.0
This release brings with it a number of minor fixes and changes,
as well as a new feature for simulating, and partially
counteracting, various forms of color blindness. For more
information see the new pl_cone_params structure and
pl_get_cone_matrix function.
Additions:
* VK_COMPOSITE_ALPHA_INHERIT_BIT_KHR is now supported, and gets
treated as PL_ALPHA_UNKNOWN.
* Add a new feature for simulating various forms of color
blindness (based on the LMS color model).
Changes:
* Setting pl_render_params.upscaler/downscaler to NULL no longer
allows automatically choosing bicubic, since this breaks
various other optimizations that are only possible when using
the built-in GPU sampling. This now only chooses
bilinear/nearest depending on the texture/hardware capabilities
* The public API of pl_shader_alloc was changed:
the uint8_t ident field was removed. This makes no real sense
to expose publicly, since users had no legitimate use for it
other than setting it to 0.
Fixes and performance improvements:
* The pl_dither_params.lut_size now gets correctly defaulted to 6
* Fixed some use-after-scope bugs in the renderer
* Fixed colorspace selection when using user-specified swapchain
formats
* Peak detection is now correctly disabled if the buffer size is
set to 0. (Before, it would default back to 63 in that case)
* Fix the out-of-gamut warning feature. This previously stopped
working for out-of-range tone mapped values.
* Sun Jul 29 2018 jengelh@inai.de
- Fix RPM groups.
* Sat Jun 09 2018 9+suse@cirno.systems
- Update to 0.5.0
This release brings with it greatly improved support for HDR (including
HDR-in-SDR emulation, native HDR passthrough and improvements to the
HDR->SDR tone mapping algorithm), as well as support for ICC profiles
and external VkImage interop (needed for e.g. hardware decoding).
Additions:
* Add support for treating an SDR curve as an HDR curve by
overriding/providing the true target peak. This essentially allows you
to calibrate a true HDR device to a typical SDR curve and use it to
display HDR media, at the cost of bit precision
* Add more values to enum pl_chroma_location
* Add a scale factor to struct pl_sample_src, which is useful for e.g.
debanding on bit-shifted inputs
* Add a new function to infer/guess unknown pl_color_space fields
* Add support for 3DLUTs / ICC profiles (via LittleCMS), including
support for assigning ICC profiles to the `pl_render_image` and
`pl_render_target` structs
* Allow enabling optional extra vulkan device/instance extensions, as
well as listing what extensions were actually loaded
* Add an API for VkImage interop with user code, e.g. to wrap mapped
hardware decoding planes into `pl_tex`, plus all synchronization code
and extra metadata necessary to make this interop safe
* Implement support for native HDR output on supported platforms
Changes:
* Separate the texture from the plane data struct in `pl_upload_plane`
* Swapchain FBOs are now guaranteed to be blittable (e.g. pl_tex_clear)
* Tone mapping is no longer done for desaturation steps. Users wanting
high quality desaturation should use ICC profiles
* Change the types of various fields in struct pl_gpu_limits
* Slightly relax the sizing requirements of pl_tex_transfer
* Change the default value for pl_tex_transfer_params.stride_w/h.
Instead of defaulting to the image size, they now default to the rect to
be transferred
* Texture transfer buffer offsets must (now) be aligned to the texel
size, in addition to being a multiple of 4
* Change the API of `pl_color_space_equal` to be consistent with the
rest of the colorspace APIs
* Allow the `pl_upload_plane` helpers to upload from buffers as well
* Switch the type of mapped buffer pointers from char* to uint8_t*
* Rename DCI_P3 to Display_P3, and add DCI_P3 (using the actual DCI white
point)
Fixes and performance improvements:
* Fix some compatibility issues with GLSL 120
* Prevent desaturation from exploding when tone mapping to HDR, or when
tone mapping a very bright HDR scene to SDR
* Implement the fully parametrized BT.2100 (HLG) OOTF in both
directions, based on the tagged/inferred signal peak
* Fix an issue preventing the out-of-gamut feature from working
correctly on HDR displays
* Fix a segfault that occurs when instance creation fails
* Fix an issue where `peak_detect_frames` was sometimes too low
* Allow debanding to take care of implicit bilinear sampling in cases
where no other scaler is requested, thus avoiding an unnecessary FBO
indirection
* Only run the debanding algorithm on the parts of the image we will
actually be displaying. This is relevant when cropping
* Fix an issue where PL_TONE_MAPPINg_MOBIUS could fail in certain
(unrealistic) scenarios involving HDR-in-SDR emulation
* Fix an issue where vulkan could sometimes modify commands after
submitting them, when recreating vertex buffers
* Make an effort to reuse the same vertex buffer when the contents don't
change from the previous invocation
* Fix the glslang locale work-arounds on windows
* Fix an issue where trying to upload from a too-large texel buffer
results in an assertion failure rather than a clean error
* Fix an issue where the usage of VkEvents prevented libplacebo from
working on platforms where they were unsupported (e.g. MoltenVK)
* Support and use vulkan push descriptors where supported. This avoids
having to maintain, update and synchronize descriptor sets
* Correctly disable signal linearization on low-bit depth FBOs
* Prevent a crash on the (pathological) case of a shader with no
descriptors
* Fix a bug in the size limit calculations for 2D/3D LUTs
* Use optimization level "performance" instead of "size" for shader
compilation
* Fix an abort() when trying to render to a non-storable FBO when using
a final pass that requires compute shaders (e.g. HDR peak detection)
