tiff with IrfanView.
Don't test with IrfanView, or Gimp, or XnView. I've just tested, these
ones have broken output, but libtiff (eg tiff2rgba) and ffmpeg do not. I
suspect most softwares do not abide by the rule set in libtiff, encode
extended image data if need be.
Second, are the softwares you use able to decode YUV with chroma
subsampling produced by either libtiff or even themselves? Is their output
decodable by libtiff? By themselves?
If you do have a file not produced by ffmpeg but that decodes well in both
libtiff and some software, that would be interesting.
