* swscale/yuv2rgb: fix conversion to X2RGB10Manuel Stoeckl2021-09-26
| | | | | | | | | This resolves a problem where conversions from YUV to X2RGB10LE would produce color values a factor 4 too small, because an 8-bit value was placed in a 10-bit channel. Signed-off-by: Manuel Stoeckl <code@mstoeckl.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swscale/swscale: Disable x86-specific code for other archesAndreas Rheinhardt2021-09-19
| | | | | | | | SSE2 is x86 specific, yet due to the call to av_get_cpu_flags() compilers were unable to optimize the checks (and the call) away on other arches. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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.

* sws: move updating the palette higher upAnton Khirnov2021-07-03
| | | | | It does not interact in any way with the code setting up the image pointers/strides, so it should not be intermixed with it.

* sws: reset sliceDir at the end of sws_scale()Anton Khirnov2021-07-03

* sws: separate the calls to scaled vs unscaled conversionAnton Khirnov2021-07-03
| | | | | | | | | | Call the scaler function directly rather than through a function pointer. Drop the now-unused return value from ff_getSwsFunc() and rename the function to reflect its new role. 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.
