六.CtsCameraTestCases模块

6.1 android.media.decoder.cts.VideoDecoderPerfTest#testPerf[14

(OMX.qcom.video.decoder.hevc:vga

log:

android.media.decoder.cts.VideoDecoderPerfTest#testPerf[9(c2.android.h263.decoder:qcif)] FAILURE: java.lang.AssertionError: Expected achievable frame rates

for c2.android.h263.decoder video/3gpp 176x144: [1374.0, 1403.0].           

Measured frame rate: [158.22103478559546, 156.59490404044968].

-》测试c2.android.h263.decoder:qcif 时走的是c2.android.h263.decoder video/3gpp 176x144 目标帧率1374/10,1403/10; 实际帧率158/10, 156/10

分析：

adb pull system/vendor/etc/media_codecs_performance.xml

 解决：帧率范围改成期望帧率：1374,1403

七.测试时间过长

android.hardware.camera2.cts.ReprocessCaptureTest#testBurstReprocessing[1]

android.hardware.camera2.cts.ReprocessCaptureTest#testMixedBurstReprocessing[1]

android.hardware.camera2.cts.ReprocessCaptureTest#testReprocessingSizeFormatWithPreview[1]

cts camera模块跑一遍需要48小时，其中上面3条就要耗用12小时左右，目前没有找到原因。
