I also get the same problem. Does anyone have solution and what is the cause?
, Nov 14, 2010
Hello. I get the same problem. I applied the patch (A). So this test passed! (A) http://android.git.kernel.org/?p=platform/cts.git;a=commit;h=cac69966080b824fe6c10a011f7d2658681ae8de

Yes, that patch should fix things. It will included in the next release.
Status: FutureRelease

android.graphics.cts.YuvImageTest.testCompressYuvToJpeg(YuvImageTest.java:189) at this line we pass two copies of the same rect[l], so effectively the altered code is doing the same job as that of unchanged code.. how is this fix solving the issue?
, Nov 16, 2010
t4tina007, the compressRects method (line 243) changed to pass in a different argument to compareBitmaps (line 255) depending on whether or not the rect1 and rect2 arguments passed to compressRects was the same. Beyond that, I can't tell you much, since this is not my area of expertise. However, here is what the reviewer commented before approving it: "...the issue is that the requested rectangle region for doing the YuvToJpeg compression may be adjusted in the cases that the left-top point of the region is located in odd-indexed position. In such cases, the rectangle in the golden test image should be adjusted accordingly."
看看补丁最新的补丁：比较一下新、旧YuvImageTest.java的不同。
修改后，测试通过！
个人觉得是因为 actual = compressDecompress(image, rect2)，当rect2的left,top是奇数时，这一句会将rect2的left,top改变。
此时而rect1和rect2是指向同一个的，所以rect1在被compressToJpeg()后，其left,top也会改变，由(11,11)变成(10,10)
