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
