thanks

Same for me :/

[smolleyes]

damn :(

something changed in ffmpeg, was working before since you builded it :p

i search for changes in upstream

[smolleyes]

it works if i use --disable-asm but don t know if it has side-effects :/

[smolleyes]

main ffmpeg delevloper say:

that looks like a bug in clang 4 rather than FFmpeg, no?
I mean, clang crashed
also llvm+clang 4.0 isn't even stable yet
see: http://llvm.org/
so yes, go provide a bug report to the llvm+clang people
it shouldn't crash

....

[vzamanillo]

You are tenacious, thank you very much!

[smolleyes]

yes... i do it once for all and next time in 3 years lol, still waiting for the account to be able to post in llvm bug tracker...

i tested the videos with the --disable-asm, i don t see any performance issue so... good for me

[vzamanillo]

Confirmed, the build ends with success disabling asm, but seems like is not a good practice, the ffmpeg crew refers to the use of that flag as "in the worst case", I don't know really why, could be related to performance but I cant not find more information about it ...

Anyway, thank you very much!!

Same asm related errors on building for windows x64
