Subject: Fix 10-bit video decode failure with --frame-parallel mode.
X-Git-Tag: v1.5.0~802^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1582ac851fc6b39549c8a57237b0619c7bcf4fcc;p=platform%2Fupstream%2Flibvpx.git

Fix 10-bit video decode failure with --frame-parallel mode.

Also add unit test to avoid same error in the future.

Issue:981
