Or was an old feature that has long ago been removed, but the documentation hasn't been updated accordingly. Or this was part of a beta or experimental feature that never got added, but was mistakenly put in the official documentation. The software is supposed to behave as the docs say, but the programmers forgot to write the functionality into the code.
I can think of several ways this may occur. The bug here is that the software is not behaving as the official documentation states. Default value is ‘auto’.Īrithmetic dither, based using xor (more random/less apparent patterning that a_dither). Here's a block quote of the relevant section there. In the official documentation at it says that for the sws_dither command line switch, that "none" is a valid value.
I guess you could try -sws_dither 0 instead.īut "none" is SUPPOSED TO BE a valid value. set dithering algorithm (from 0 to 6) (default auto)Ī_dither 4 E.V.
This is the relevant part of ffmpeg -h filter=scale:
