Mark Reid	3f4ce004b8	swscale/input: clip rgbf32 values before lrintf if the float pixel * 65535.0f > 2147483647.0f lrintf may overfow and return negative values, depending on implementation. nan and +/-inf values may also be implementation defined clip the value first so lrintf always works. values < 0.0f, -inf, nan = 0.0f values > 65535.0f, +inf = 65535.0f old timings 195960 decicycles in planar_rgbf32le_to_uv, 1 runs, 0 skips 186120 decicycles in planar_rgbf32le_to_uv, 2 runs, 0 skips 188645 decicycles in planar_rgbf32le_to_uv, 4 runs, 0 skips 183625 decicycles in planar_rgbf32le_to_uv, 8 runs, 0 skips 181157 decicycles in planar_rgbf32le_to_uv, 16 runs, 0 skips 177533 decicycles in planar_rgbf32le_to_uv, 32 runs, 0 skips 175689 decicycles in planar_rgbf32le_to_uv, 64 runs, 0 skips 232960 decicycles in planar_rgbf32be_to_uv, 1 runs, 0 skips 221380 decicycles in planar_rgbf32be_to_uv, 2 runs, 0 skips 216640 decicycles in planar_rgbf32be_to_uv, 4 runs, 0 skips 213505 decicycles in planar_rgbf32be_to_uv, 8 runs, 0 skips 211558 decicycles in planar_rgbf32be_to_uv, 16 runs, 0 skips 210596 decicycles in planar_rgbf32be_to_uv, 32 runs, 0 skips 210202 decicycles in planar_rgbf32be_to_uv, 64 runs, 0 skips 161680 decicycles in planar_rgbf32le_to_y, 1 runs, 0 skips 153540 decicycles in planar_rgbf32le_to_y, 2 runs, 0 skips 148255 decicycles in planar_rgbf32le_to_y, 4 runs, 0 skips 140600 decicycles in planar_rgbf32le_to_y, 8 runs, 0 skips 132935 decicycles in planar_rgbf32le_to_y, 16 runs, 0 skips 128531 decicycles in planar_rgbf32le_to_y, 32 runs, 0 skips 140933 decicycles in planar_rgbf32le_to_y, 64 runs, 0 skips 190980 decicycles in planar_rgbf32be_to_y, 1 runs, 0 skips 176080 decicycles in planar_rgbf32be_to_y, 2 runs, 0 skips 167980 decicycles in planar_rgbf32be_to_y, 4 runs, 0 skips 164685 decicycles in planar_rgbf32be_to_y, 8 runs, 0 skips 162751 decicycles in planar_rgbf32be_to_y, 16 runs, 0 skips 162404 decicycles in planar_rgbf32be_to_y, 32 runs, 0 skips 167849 decicycles in planar_rgbf32be_to_y, 64 runs, 0 skips new timings 183320 decicycles in planar_rgbf32le_to_uv, 1 runs, 0 skips 175700 decicycles in planar_rgbf32le_to_uv, 2 runs, 0 skips 179570 decicycles in planar_rgbf32le_to_uv, 4 runs, 0 skips 172932 decicycles in planar_rgbf32le_to_uv, 8 runs, 0 skips 168707 decicycles in planar_rgbf32le_to_uv, 16 runs, 0 skips 165224 decicycles in planar_rgbf32le_to_uv, 32 runs, 0 skips 163423 decicycles in planar_rgbf32le_to_uv, 64 runs, 0 skips 184940 decicycles in planar_rgbf32be_to_uv, 1 runs, 0 skips 185150 decicycles in planar_rgbf32be_to_uv, 2 runs, 0 skips 185790 decicycles in planar_rgbf32be_to_uv, 4 runs, 0 skips 185472 decicycles in planar_rgbf32be_to_uv, 8 runs, 0 skips 185277 decicycles in planar_rgbf32be_to_uv, 16 runs, 0 skips 185813 decicycles in planar_rgbf32be_to_uv, 32 runs, 0 skips 185332 decicycles in planar_rgbf32be_to_uv, 64 runs, 0 skips 145400 decicycles in planar_rgbf32le_to_y, 1 runs, 0 skips 145100 decicycles in planar_rgbf32le_to_y, 2 runs, 0 skips 143490 decicycles in planar_rgbf32le_to_y, 4 runs, 0 skips 136687 decicycles in planar_rgbf32le_to_y, 8 runs, 0 skips 131271 decicycles in planar_rgbf32le_to_y, 16 runs, 0 skips 128698 decicycles in planar_rgbf32le_to_y, 32 runs, 0 skips 127170 decicycles in planar_rgbf32le_to_y, 64 runs, 0 skips 156020 decicycles in planar_rgbf32be_to_y, 1 runs, 0 skips 146990 decicycles in planar_rgbf32be_to_y, 2 runs, 0 skips 142020 decicycles in planar_rgbf32be_to_y, 4 runs, 0 skips 141052 decicycles in planar_rgbf32be_to_y, 8 runs, 0 skips 138973 decicycles in planar_rgbf32be_to_y, 16 runs, 0 skips 138027 decicycles in planar_rgbf32be_to_y, 32 runs, 0 skips 143939 decicycles in planar_rgbf32be_to_y, 64 runs, 0 skips Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Almer <jamrial@gmail.com>	3 years ago

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.
