* avutil/utils: Remove racy check from avutil_version()Andreas Rheinhardt2021-09-29
| | | | | | | | | | | | | | | | avutil_version() currently performs several checks before just returning the version. There is a static int that aims to ensure that these tests are run only once. The reason is that there used to be a slightly expensive check, but it has been removed in 92e3a6fdac73f7e1d69d69717219a7538877d7a0. Today running only once is unnecessary and can be counterproductive: GCC 10 optimizes all the actual checks away, but the checks_done variable and the code setting it has been kept. Given that this check is inherently racy (it uses non-atomic variables), it is best to just remove it.

| | | | | | | | | | | The new format (given in big/little endian forms) matches the existing X2RGB10 format, except with B and R channels switched. AV_PIX_FMT_X2BGR10 data often is created by OpenGL programs whose buffers use the GL_RGB10 internal format.

* libavutil/hwcontext_d3d11va: adding more texture information to the D3D11 ↵Artem Galin2021-09-08
| | | | | | | | | | | | hwcontext API Microsoft VideoProcessor requires texture with D3DUSAGE_RENDERTARGET flag as output. There is no way to allocate array of textures with D3D11_BIND_RENDER_TARGET flag and .ArraySize > 2 by ID3D11Device_CreateTexture2D due to the Microsoft limitation. Adding AVD3D11FrameDescriptors array to store array of single textures instead of texture with multiple slices resolves this. Signed-off-by: Artem Galin <artem.galin@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | From SMPTE RDD 5-2006, the grain seed is to be computed from the following definition of `pic_offset`: > When decoding H.264 | MPEG-4 AVC bitstreams, pic_offset is defined as > follows: > - pic_offset = PicOrderCnt(CurrPic) + (PicOrderCnt_offset << 5) > where: > - PicOrderCnt(CurrPic) is the picture order count of the current frame, > which shall be derived from [the video stream]. > > - PicOrderCnt_offset is set to idr_pic_id on IDR frames. idr_pic_id > shall be read from the slice header of [the video stream]. On non-IDR I > frames, PicOrderCnt_offset is set to 0. A frame shall be classified as I > frame when all its slices are I slices, which may be optionally > designated by setting primary_pic_type to 0 in the access delimiter NAL > unit. Otherwise, PicOrderCnt_offset it not changed. PicOrderCnt_offset is > updated in decoding order.

* imgutils: expose av_image_copy_plane_uc_from()Lynne2021-08-14
| | | | | | | | | | | | The reason why the generic av_image_copy_uc_from() doesn't really fit in the case for Vulkan is because some planes may be copied via other methods (such as mapping GPU memory), and if they don't satisfy the strict alignment requirements, a gpu image->gpu buffer->cpu ram copy is performed. We need this for hwcontext_vulkan, and I think this will also be useful to API users like libplacebo who would rather not write a custom SIMD memcpy.

| | | | | | | | | | | | | Since 580e168a945b65100ec2c25433f33bfacfe9f7be, av_size_mult() is no longer inlined; on systems where interposing is a thing, this also inhibits the compiler from inlining said function into the internal callers of said function, although inlining such a small function is typically beneficial: With GCC 10.3 on Ubuntu x64 and -O3 this decreases the size of av_realloc_array from 91B to 23B, from 129B to 81B for av_realloc_f and from 77B to 23B for each of av_malloc_array, av_mallocz_array and av_calloc.
