- 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~rc4
  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 11:18:38 UTC 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.

Sat Jun  9 15:43:18 UTC 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)
