This changes the output for: ./ffmpeg -i ~/tickets/4926/5611842b1f09f2_20295212.png -vf scale=34:44 file.tga same with png output That is the red looks a bit different, the filesize also changes file should be here: https://trac.ffmpeg.org/attachment/ticket/4926/5611842b1f09f2_20295212.png I dont know if the one after the patch is more or less correct, but why does your patch change this ? is that change intentional ? thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Awnsering whenever a program halts or runs forever is On a turing machine, in general impossible (turings halting problem). On any real computer, always possible as a real computer has a finite number of states N, and will either halt in less than N cycles or never halt.
