swscale/x86/yuv2rgb: Remove obsolete MMX functions
x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> |

swscale/x86/yuv_2_rgb: fix access to memory past the frame data in yuv to rgb conversion
Y, U, V data is loaded at the end of the current iteration for the next iteration. It results in memory access past the frame data on the last iteration (that data is never used after the loading). So load data at the start of the iteration, so that only useful data is loaded. Signed-off-by: Vardan Margaryan <v.t.margaryan@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net> |

libswscale/x86/yuv2rgb: add ssse3 version
Tested using this command: /ffmpeg -pix_fmt yuv420p -s 1920*1080 -i ArashRawYuv420.yuv \ -vcodec rawvideo -s 1920*1080 -pix_fmt rgb24 -f null /dev/null The fps increase from 389 to 640 on Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz Signed-off-by: Ting Fu <ting.fu@intel.com> |

libswscale/x86/yuv2rgb: Change inline assembly into nasm code
The original inline assembly and nasm code have the same fps when called by command. NASM code almost has no impact on the perfromance. Signed-off-by: Ting Fu <ting.fu@intel.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> |
