Comment (by kurosu):

 So I had noticed the same, but assumed only Vittorio's additions were
 affected.

 It's nice you noticed e95018b694c0774477abec5bbf86ecc7946a9a28 was also
 affected. Strange for Kostya, but seems so. As for 1256's luma, it reuses
 1235's. Original VLC ticket at [https://trac.videolan.org/vlc/ticket/9620]
 should allow a bit of testing.

 I'll send a patchset with all changes if everybody confirms it improves
 things.
