I'm sorry, but the high-entropy-va is ebabled.

$ peflags -v /usr/bin/ff{mpeg,probe,play}
/usr/bin/ffmpeg: coff(0x022e[+executable_image,+line_nums_stripped,+local_syms_stripped,+bigaddr,+sepdbg]) pe(0x8160[+high-entropy-va,+dynamicbase,+nxcompat,+tsaware])
/usr/bin/ffprobe: coff(0x022e[+executable_image,+line_nums_stripped,+local_syms_stripped,+bigaddr,+sepdbg]) pe(0x8160[+high-entropy-va,+dynamicbase,+nxcompat,+tsaware])
/usr/bin/ffplay: coff(0x022e[+executable_image,+line_nums_stripped,+local_syms_stripped,+bigaddr,+sepdbg]) pe(0x8160[+high-entropy-va,+dynamicbase,+nxcompat,+tsaware])

peflags -e0 /usr/bin/ff{mpeg,probe,play} solves the issue.
Thansk!

Shoud I remove dynamicbase flag as well?
