Subject: Two tables in truemotion1data.h were slightly different from VpVision
X-Git-Tag: v0.5~13479
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c017693c9388ba1284c58fbb930577727d8c206;p=platform%2Fupstream%2Flibav.git

Two tables in truemotion1data.h were slightly different from VpVision
source. This patch fixes decoding of some samples from Phantasmagoria 2
(they use delta tables N1, not N0 as the rest of files).
