Subject: fix a bug related to gf_active_flags in multi-threaded encoder
X-Git-Tag: 1.0_branch~479^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89c6017cc03082c78c6058db85cd22027230927c;p=profile%2Fivi%2Flibvpx.git

fix a bug related to gf_active_flags in multi-threaded encoder

Paul pointed out that the pointer to the gf_active_flags is not being
properly incremented in multithreaded encoder. This commit fixes the
issue by making sure the gf_active_ptr points to the starting of next
group of mb rows.
