Here are the flags which it finds on my Ivy Bridge CPU: CPU_FLAGS_X86="aes avx mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" But I had the sse4 flag (used by ffmpeg) which it didn't find. Attached /proc/cpuinfo Reproducible: Always
Created attachment 395108 [details] cpuinfo
There no such thing as 'sse4'. ffmpeg was incorrect and it will be fixed when switched to CPU_FLAGS_X86.
