Subject: Removed prediction_error accumulation
X-Git-Tag: 1.0_branch~685
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9e7fec216e37e6efe364428d9cba2f7b70f8ef3a;p=profile%2Fivi%2Flibvpx.git

Removed prediction_error accumulation

from vp8cx_encode_intra_macro_block.  prediction_error is used when
deciding if a frame should be a keyframe.  After reviewing this with
Yaowu, it was pointed out that vp8cx_encode_intra_macro_block
is only called for keyframes, so the accumulation is unnecessary.
