Ah, yeah, the case against mapped addresses did not make it to RFC status, likely because the main author tragically died, see draft-itojun-v6ops-v4mapped-harmful. But anyway, I am not a vendor of IP stacks. I am just the messenger here: mapped addresses are not portable and so you should not rely on them in portable code. _______________________________________________ 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".
