This patch broke compilation on ppc64be with gcc 9.3 (Debian sid): src/libswscale/ppc/yuv2rgb_altivec.c: In function ‘altivec_yuv2_abgr’: src/libswscale/ppc/yuv2rgb_altivec.c:338:18: error: implicit declaration of function ‘vec_xl’; did you mean ‘vec_rl’? [-Werror=implicit-function-declaration] 338 | y0 = vec_xl(0, y1i); Carl Eugen _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
