That's completely arbitrary, TBH. Both cases are syntax errors, and there are no particular reasons to tolerate one but not the other. And even if it constitued a sensible distinction, that's simply not how strtoul() handles overflow: it returns ULONG_MAX, not a wrapped-around value. In this case, both error cases are strong signs of a typing error or corruption. _______________________________________________ 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".
