* swscale/utils: Derive range from YUVJ-pix-fmt only onceAndreas Rheinhardt2022-11-24
| | | | | | | | | | | | | | Currently, it is done once per slice-thread, leading to one warning per slice-thread in case a YUVJ pixel format has been originally used. This also fixes the anomaly that said parameter are only updated for the user-facing context (whose values are retrievable via av_opt_get()) if slice-threading is not in use. Fixes ticket #9860.

* swscale/utils: Factor initializing single slice context outAndreas Rheinhardt2022-11-24
| | | | | | | | | | | | | | | | | | Initializing slice threads currently uses the function (sws_init_context()) that is also used for initializing user-facing contexts with the only difference being that nb_threads is set to one before initializing the slice contexts. Yet sws_init_context() also initializes lots of stuff that is not slice-dependent, i.e. (src|dst)Range. This currently only works because the code sets these fields to the same values for all slice contexts. This is not nice; even worse, it entails that log messages are printed once per slice context (and therefore fill the screen). This commit lays the groundwork to fix this.

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* swscale/aarch64: add hscale specializationsSwinney, Jonathan2022-05-28
| | | | | | | | | | | | | | | | | | | | | | | This patch adds code to support specializations of the hscale function and adds a specialization for filterSize == 4. ff_hscale8to15_4_neon is a complete rewrite. Since the main bottleneck here is loading the data from src, this data is loaded a whole block ahead and stored back to the stack to be loaded again with ld4. This arranges the data for most efficient use of the vector instructions and removes the need for completion adds at the end. The number of iterations of the C per iteration of the assembly is increased from 4 to 8, but because of the prefetching, there must be a special section without prefetching when dstW < 16. This improves speed on Graviton 2 (Neoverse N1) dramatically in the case where previously fs=8 would have been required. before: hscale_8_to_15__fs_8_dstW_512_neon: 1962.8 after : hscale_8_to_15__fs_4_dstW_512_neon: 1220.9 Signed-off-by: Jonathan Swinney <jswinney@amazon.com> Signed-off-by: Martin Storsjö <martin@martin.st>

* swscale: Take the destination range into account for yuv->rgb->yuv conversionsMartin Storsjö2022-02-25
| | | | | | | | | | | | The range parameters need to be set up before calling sws_init_context (which selects which fastpaths can be used; this gets called by sws_getContext); solely passing them via sws_setColorspaceDetails isn't enough. This fixes producing full range YUV range output when doing YUV->YUV conversions between different YUV color spaces. Signed-off-by: Martin Storsjö <martin@martin.st>

* swscale/swscale: Fix races when using unaligned strides/dataAndreas Rheinhardt2021-09-19
| | | | | | | | | | | | | | | | | | | | | | | | In this case the current code tries to warn once; to do so, it uses ordinary static ints to store whether the warning has already been emitted. This is both a data race (and therefore undefined behaviour) as well as a race condition, because it is really possible for multiple threads to be the one thread to emit the warning. This is actually common since the introduction of the new multithreaded scaling API. This commit fixes this by using atomic integers for the state; furthermore, these are not static anymore, but rather contained in the user-facing SwsContext (i.e. the parent SwsContext in case of slice-threading). Given that these atomic variables are not intended for synchronization at all (but only for atomicity, i.e. only to output the warning once), the atomic operations use memory_order_relaxed. This affected the nv12, nv21, yuv420, yuv420p10, yuv422, yuv422p10 and yuv444 filter-overlay FATE-tests.

This will be useful in the following commits, where it will become important that the amount of output is different for scaled vs unscaled case.
