From: Andreas Rheinhardt <andreas.rheinha...@outlook.com>
It used to be a tri-state encoding both whether to use FLV picture
headers and whether to use the FLV way of encoding escape values,
but the former is now unnecessary due to the switch to a function
pointer for reading the header. So binarize h263_flv.
