Arm unittest failures #479

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
3 unittests are failing on arm:

[  FAILED  ] libyuvTest.TestJ420
Likely its just the test, because the actual I420ToARGB passed.

[  FAILED  ] libyuvTest.ARGBSobelToPlane_Any
The odd width support must be wrong?

[  FAILED  ] libyuvTest.TestScaleJ420
Same as TestI420.  This test doesnt actually do anything useful yet, so I'll 
disable.

r1454 fixes libyuvTest.ARGBSobelToPlane_Any and disables TestScaleJ420
