 (Is it possible that you did not test the sample attached here?)

 This issue is about libavcodec encoding yuv410p input to tiff and
 ImageMagick and FFmpeg disagreeing on how to display / encode the
 rightmost pixels if the tiff file has odd width (and gimp agreeing with
 ImageMagick). It is only related to a specific part of the tiff
 specification (and its interpretation) afaict.
 The issue you just reported is related to libswscale (and unrelated to
 tiff apart from the fact that it is easier to reproduce with tiff input).
