Soft Works	58dce6f010	swscale/swscale: check SWS_PRINT_INFO flag for printing alignment warnings This makes output consistent with a similar warning just few lines above where this flag is checked in the same way.

Michael Niedermayer	f801207568	swscale/swscale: Pass slice location into unscaled code also for dst scaling Fixes: alphablend=checkerboard Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	3 years ago
Andreas Rheinhardt	044a7c08dc	swscale/swscale: Disable x86-specific code for other arches 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.

Andreas Rheinhardt	f440c422b7	swscale/swscale: Fix races when using unaligned strides/data 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.

Anton Khirnov	37c0fe49b7	sws: move updating the palette higher up It does not interact in any way with the code setting up the image pointers/strides, so it should not be intermixed with it.	4 years ago

Anton Khirnov	fe490ec165	sws: separate the calls to scaled vs unscaled conversion 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.	4 years ago
