# exercises: The same silent drop as anim-empty-frame, with nothing left
#   behind it. The frame list stays empty, and IsValidExtendedFormat()
#   refuses a finished file with no frames at all -- so what the demuxer
#   tolerates in the middle of a sequence it will not tolerate as the whole
#   of one.
