i dont know if this is a bug or just somethig that by sheer bad luck becomes vissible after this but ./ffmpeg -i cvid/dday.mov -vframes 30 -vcodec huffyuv -y -acodec pcm_s16le out3b.avi ; md5sum out3b.avi gives different outputs from time to time needs threads on the encoder side, huffyuv, vframes (audio codec irrelevant) difference in output files looks like this: valgrind shows nothing (but difference occurs under valgrind) should be here: http://samples.ffmpeg.org/V-codecs/CVID/grayscale/dday.mov --- A 2016-12-19 23:36:43.297001535 +0100 +++ B 2016-12-19 23:36:47.605001627 +0100 @@ -50,9 +50,7 @@ 0, 16, 16, 1, 54316, 0xdca6a02a 1, 18728, 18728, 1024, 2048, 0xf24df16c 0, 17, 17, 1, 55204, 0xa93a73e6 -1, 19752, 19752, 1024, 2048, 0x27c11d5c 0, 18, 18, 1, 54872, 0x8b01d9b0 -1, 20776, 20776, 1024, 2048, 0x77e00ab9 0, 19, 19, 1, 54544, 0x752b168f 0, 20, 20, 1, 58916, 0x1596d7cf 0, 21, 21, 1, 53868, 0x0f286854 [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety -- Benjamin Franklin
