s.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_l

 解决：帧率范围改成期望帧率：1374,1403
