# exercises: How far such a file gets, which is not far. An application
#   reaches the demuxer through a format check first -- anim_util.c calls
#   WebPGetInfo() -- and that is the still-image header walk, which looks
#   for VP8 or VP8L where this file has ANIM and refuses it as a bad
#   signature. The demuxer would have refused it too, one layer down: its
#   master chunk table has three entries, VP8, VP8L and VP8X, and a file
#   beginning with none of them matches no parser at all.
