Description Tobias Burnus 2023-10-04 13:27:26 UTC 
GNU Binutils 2.41 now reveals a bug in the 'asm' code used in ffmpeg-4:

 ./libavcodec/x86/mathops.h:125: Error: operand type mismatch for `shr'

While Binutils is pending for opensuse:factory, the new version has already landed in 15.4 and 15.5 such that ffmpeg-4 fails there:

https://build.opensuse.org/package/show/multimedia:libs/ffmpeg-4

ffmpeg-5/6 seemingly got the fix as I do see no fails for 15.4/15.5 for the build of the 4h old package.


Upstream FIX:  "Fixes assembling with binutil as >= 2.41" at
