  - 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
    * 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

  - 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.
    * add pl_gpu.pci, containing the PCI address of the underlying
    * 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_shader_encode_color now handles non-linear color systems
    * add pl_render_params.force_dither, to force use of the dither
    * add pl_render_params.disable_fbos, to forcibly disable FBOs
    * add pl_vk_inst_params.layers, to allow loading extra vulkan
    * add a way to restrict the maximum GLSL version provided by the
      various pl_gpu backends, for testing purposes
    * load all vulkan function pointers indirectly, using a
      user-provided vkGetInstanceProcAddr function
    * vulkan can now be built without linking against
    * 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
    * 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

  - 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.
    * 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 <>
  - 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
    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.
    * 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
    * 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
    * 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
    * 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
    * 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 <>
  - 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.
    * shaders.h API users can now override the GLSL version
    * add support for vulkan platforms with non-coherent memory
      (e.g. iGPUs)
    * 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 <>
  - 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.
    * 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
    * 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.
    * 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
    * 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
    * 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 <>
  - 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.
    * 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.
    * 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
    * 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
    * 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 <>
  - 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.
    * 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).
    * 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
    * 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
  - Fix RPM groups.
* Sat Jun 09 2018
  - 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).
    * 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
    * 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
    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
    * 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
    * Fix a bug in the size limit calculations for 2D/3D LUTs
    * Use optimization level "performance" instead of "size" for shader
    * 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)
