fail:
junit.framework.AssertionFailedError: rms error is bigger than the limit [1.705549439004595, 1.7481510867834686, 45.12865402872597, 45.55498948157783, 22.659392092463555, 12.045954830472251, 36.54067065917403, 21.267713558349428, 9.689990540071062, 6.778597281968527, 32.54079661662333, 9.445533041837525, 18.634087700889584, 6.7517520359944765, 20.300935747453178, 17.36366100029983, 46.599351736072705, 15.336949935803185, 17.07504797455437, 4.151855140911242] vs 20.0
這個是cache 機制差異的問題
6771 少了 HW access 後的invalidate ，這個測項後面接的是google SW codec 才會機率性fail
