  • v3.120.0   v3.120.0 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 - add `pl_shared_mem.stride_w/h` to control dmabuf pitch - add `pl_render_image_mix` to blend multiple frames into a single output image, given relative timestamp information - add the `pl_filter_mitchell_clamp` filter preset - add `pl_render_params.preserve_mixing_cache` to speed up redraws after renderer size changes when frame mixing is active - add <libplacebo/utils/dav1d.h> to help with Dav1dPicture mapping - implement `PL_HANDLE_HOST_PTR` for the OpenGL backend - implement drm format modifiers for vulkan - add a new field `pl_fmt.modifiers` for DRM format modifier negotiation - add new header <libplacebo/shaders/lut.h> to load custom LUTs (currently only supporting the .cube format) - add `index_data/buf` to `pl_pass_run_params`, adding support for 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 - add `pl_frame_recreate_from_avframe` and `pl_download_avframe` to help downloading GPU textures back into AVFrame form - add a new header <libplacebo/utils/frame_queue.h> to assist in taking a stream of (Frame, PTS) pairs as well as a list of VSync times and turning them into a stream of `pl_frame_mix` structs - add `pl_white_from_temp` and `pl_color_adjustment.temperature` to apply white point adjustments between correlated color temperatures (K) - add `pl_filter_preset.description` containing a longer, human-readable 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` Fixes and performance improvements: - fix buffer overflow in custom shader STORAGE blocks - fix include path for glslang >= 11.0.0 - actually enable shader subgroup operations for HDR peak detection - fix locale dependence of shader parsing primitives - fix AVCOL_SPC_SMPTE170M mapping - fix wrong color space selection in `pl_vulkan_create_swapchain` - work-around low UBO size limits on some platforms - fix compilation issues on C++ due to the use of reserved identifiers - fix `pl_get_detected_peak` on platforms without host-visible SSBOs - fix edge case in vulkan texture handle capabilities check - fix suboptimal mutex destruction code - skip peak detection when outputting to HDR displays - fix edge cases in shader LUT type selection logic - avoid redundant scaling passes when scaling anamorphic content - merge similar planes before dispatching heavy shaders (e.g. debanding, hooks) - avoid scaling passes for certain small fractional scaling steps - entirely avoid processing unneeded components when dispatching scalers - avoid using more components than necessary for intermediate FBOs - fix out-of-bounds read for small non-cropped emulated textures - avoid thrashing the shader cache when reinitializing OpenGL FBOs - fix incorrect include in <libplacebo/opengl.h> - fix vk.xml priority issue on windows - fix undefined behaviour / GPU hangs in HDR peak detection shader - fix incorrect forwarding of DRM modifiers to the OpenGL backend - fix crash on AV_PIX_FMT_FLAG_BAYER - fix various compilation issues on certain platforms - fix obscure edge-case in floating point printing routine - `pl_render_params.force_icc_lut` now excludes no-op cases - fix handling of custom shader COMPUTE blocks - correctly apply hue and saturation controls for non-YCbCr color spaces
  • v3.104.0   v3.104.0 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` -

  • v2.72.0   v2.72.0 This is a major release with several key additions, most notably being the support for custom, mpv-style "user shaders" (.hook), giving us access to a large variety of pre-existing user shaders such as RAVU, FSRCNNX, Anime4K, SSimSuperRes, KrigBilateral, NNEDI3, and more. In addition to this, major additions include a completely refactored and fixed AV1 grain generation shader, support for Vulkan versions higher than 1.0, support for GPU-based timers, and improved interop APIs for both Vulkan and OpenGL, and new and improved aspect ratio handling. Finally, this release also brings with it a major change to the way HDR and SDR content are mapped between each other, including a new tone-mapping function based on the industry-standard ITU-R BT.2390 EETF.

  • v2.43.0   v2.43.0 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

  • v1.29.1   v1.29.1 This is a minor bug fix follow-up, to address one major and two minor issues with the v1.29.0 release. Fixes: - fix a segfault in the test framework on platforms without vulkan - fix error message spam when rendering to minimized/hidden windows - hackily fix compilation on certain glslang versions
  • v1.29.0   v1.29.0 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
  • v1.21.0   v1.21.0 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
  • v1.18.0   v1.18.0 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.
  • v1.7.0   v1.7.0 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. This release also marks our move from GitHub to VideoLAN's GitLab. May they provide a home for us for a long time going forwards. 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: - Meson 0.47 is correctly marked as the minimum required version. - Fix compilation on clang. - Fix compilation on glslang git master. - Fix compilation with older shaderc versions. - Fix compilation on some platforms. - 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. - Fix build issues on Android arm32. - 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. - Speed up compilation by skipping glslang when shaderc is available. - 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.

  • v1.7.0-rc4   v1.7.0-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. This release also marks our move from GitHub to VideoLAN's GitLab. May they provide a home for us for a long time going forwards. 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.
