Comment (by Balling):

 Replying to [comment:1 ami_stuff]:
 > {{{2_2_2__21_21_21_YCbCrK.jpg}}} has 0x21212121 pix_fmt id, not sure if
 it decodes "by luck" or is really supported.

 Yeah, I also cannot see this pixel format, but maybe it was added with
 this commit: d56c373391d334d3dc29c752955fd17f0cef7ff9
