Subject: get/show_bits() can read up to MIN_CACHE_BITS bits
X-Git-Tag: v0.6~1176
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=39261cd8d992322ce8ad77ee76a63a683cca21b2;p=platform%2Fupstream%2Flibav.git

get/show_bits() can read up to MIN_CACHE_BITS bits

The limit for get/show_bits_long() to use get/show_bits() directly
should be MIN_CACHE_BITS, not 17.
