* avutil/slicethread: Mark avpriv_slicethread_{create,free} as av_coldAndreas Rheinhardt2025-03-261-1/+2

* avutil/slicethread: Remove NULL pointer check when freeingAndreas Rheinhardt2025-03-261-3/+2
| | | | | | | | | | avpriv_slicethread_free() is one of our functions that takes a pointer to a pointer and resets the pointer when done. It is legal for such functions to be passed a pointer to a NULL pointer, yet passing a NULL pointer would be insane and should not be tolerated.

* avutil/csp: Improve enum range comparisonsAndreas Rheinhardt2025-03-211-7/+7
| | | | | | | | | | | | | | | | | | | The underlying integer type of an enumeration is implementation-defined (see C11, 6.7.2.2 (4)); GCC defaults to unsigned if there are no negative values like for all enums from pixfmt.h except enum AVPixelFormat. This means that tests like "if (csp >= AVCOL_SPC_NB)" for invalid colorspaces need not work as expected (namely if enum AVColorSpace is signed). It also means that testing for such an enum variable to be >= 0 may be tautologically true. Clang emits a -Wtautological-unsigned-enum-zero-compare warning for this. Fix both of these issues by casting to unsigned. Also do the same in libswscale/format.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* pixfmt: add AV_PIX_FMT_GBRAP32Lynne2025-03-173-1/+33
| | | | | | This commit adds a 32-bit *integer* planar RGBA format. Vulkan FFv1 decoding is best performed on separate planes, rather than packed RGBA (i.e. RGBA128), hence this is useful as an intermediate format.
* all: Fix doxy comments wrongly designated as trailing ///<Andreas Rheinhardt2025-03-121-1/+1
| | | | | | | | | | | The ///< or /**< form of doxygen comments are only to be used when the documentation follows the member and the comment block starts on the same line as the member. This commit fixes wrong uses of them; in particular, this fixes the comment for mb_height in H.264 SPS's structure which was wrongly added to mb_width.

* hwcontext_vulkan: add support for mapping multiplane images into CUDALynne2025-03-111-102/+160
| | | | | | | | | | | | | This patch refactors the CUDA import code to allow for Vulkan images with multiple planes to be mapped. Currently, a driver bug exists which causes NV12 images to be mapped incorrectly when the memory being mapped contains both planes, the issue has been reported to NVIDIA. yuv420p does work correctly, however. This is still an improvement, as the code used to crash when trying to map the memory, unless disable_multiplane=1 was given as an option.

| | | | | | | | Otherwise it is possible for av_log() to receive a non-NULL object with a NULL AVClass pointer; the default log callback handles it gracefully, yet this is probably an API violation. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* vulkan: take refs of frames using the regular buffer ref pathLynne2025-03-031-6/+14
| | | | | | | | | | | This simplifies the code, reduces allocations, and critically, does not store references of frames, along with references to hw_frames_ctx. The issue was that storing refs to frames while transferring stored refs to hw_frames_ctx of frames, and so created a circular dependency, which caused the Vulkan device to never be terminated. This only stores what it strictly needs as a dependency, and enables the frames context to be freed, even while doing asynchronous transfers.

* hwcontext_vulkan: enable read/write without storageLynne2025-02-271-0/+2
| | | | | | | | | | BGR formats in Vulkan cannot be used in storage images, as the pixel labels on storage images are always ordered as RGB, and swizzling is not an option due to old hardware limitations. This means that you must always use an RGB format and manually swizzle when reading or writing to BGR images, or simply not use a format in the shader itself. This adds support for the latter.
* vulkan: add .buf_elems to FFVulkanDescriptorSetLynne2025-02-212-2/+3
| | | | | | | | | | This enables users to specify a number that would be appended to the buf_content string. Saves users from needing to manually print to a string. An earlier commit tried doing this via .elems, but it was faulty, as this also incremented the total number of descriptors in the descriptor set.

* random_seed: Improve behaviour with small timer increments with high ↵Martin Storsjö2025-02-131-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | precision timers On a Zen 5, on Ubuntu 24.04 (with CLOCKS_PER_SEC 1000000), the value of clock() in this loop increments by 0 most of the time, and when it does increment, it usually increments by 1 compared to the previous round. Due to the "last_t + 2*last_td + (CLOCKS_PER_SEC > 1000) >= t" expression, we only manage to take one step forward in this loop (incrementing i) if clock() increments by 2, while it incremented by 0 in the previous iteration (last_td). This is similar to the change done in c4152fc42e480c41efb7f761b1bbe5f0bc43d5bc, to speed it up on systems with very small CLOCKS_PER_SEC. However in this case, CLOCKS_PER_SEC is still very large, but the machine is fast enough to hit every clock increment repeatedly. For this case, use the number of repetitions of each timer value as entropy source; require a change in the number of repetitions in order to proceed to the next buffer index. This helps the fate-random-seed test to actually terminate within a reasonable time on such a system (where it previously could hang, running for many minutes).

* avutil: add hwcontext_amf.Dmitrii Ovchinnikov2025-02-049-0/+718
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds hwcontext_amf, enabling a shared AMF context for encoders, decoders, and AMF-based filters, without copy to the host memory. Code also was tested in HandBrake. Benefits: - Optimizations for direct video memory access from CPU - Significant performance boost in full AMF pipelines with filters - Integration of GPU filters like VPP, Super Resolution, and Compression Artefact Removal(in future plans) - VCN power management control for decoders. - Ability to specify which VCN instance to use for decoding (like for encoder) - AMD will soon introduce full AMF API for multimedia accelerator MA35D - With AMF API, integration will be much easier: GPU and the accelerator will have the same API - including encoder, decoder, scaler, color converter, Windows and Linux. Learn more: https://www.amd.com/en/products/accelerators/alveo/ma35d.html Changes by versions: v2: Header file cleanup. v3: Removed an unnecessary class. v4: code cleanup and improved error handling v5: Fixes related to HandBrake integration. v6: Sequential filters error and memory leak have been fixed.
