RK3576 android14 GMS CtsVideoTestCases 测试fail
平台：RK3576，android14
CtsVideoTestCases 测试有如下fail
可以看到错误大体上分为两种类型 testPerformanceOfHardwareVideoEncoders 和 testPerf
先看 testPerformanceOfHardwareVideoEncoders 的测试源码。
public void testPerformanceOfHardwareVideoEncoders() throws IOException, InterruptedException {
encode();
String log = String.format("DecodeMime: %s, Decoder: %s, resolution: %dp, EncodeMime: %s," +
" Encoder: %s, Key-priority: %d :: ", mDecoderMime, mDecoderName, mHeight,
mEncoderMime, mEncoderName, mKeyPriority);
int maxExpectedFps = getMaxExpectedFps(mWidth, mHeight);
double fpsToleranceFactor = FPS_TOLERANCE_FACTOR;
if (VNDK_VERSION <= Build.VERSION_CODES.TIRAMISU) {
fpsToleranceFactor = Math.min(0.9, fpsToleranceFactor);
}
double expectedFps =
Math.min(mOperatingRateExpected * fpsToleranceFactor, maxExpectedFps);
Log.d(LOG_TAG, log + "act/exp fps: " + mAchievedFps + "/" + expectedFps);
assertTrue("Unable to achieve the expected rate. " + log + "act/exp fps: " + mAchievedFps
+ "/" + expectedFps, mAchievedFps >= expectedFps);
}
这是测试 你的实际帧率 必须大于 期望帧率。
已第一个测试个例为例子：
| android.video.cts.CodecEncoderPerformanceTest#testPerformanceOfHardwareVideoEncoders[193_c2.rk.hevc.decoder_video/avc_c2.rk.avc.encoder_1_2.5_true_2] |
fail

java.lang.AssertionError: Unable to achieve the expected rate. DecodeMime: video/hevc, Decoder: c2.rk.hevc.decoder, resolution: 2160p, EncodeMime: video/avc, Encoder: c2.rk.avc.encoder, Key-priority: 1 :: act/exp fps: 26.915002422350216/28.5

需要找到 c2.rk.avc.encoder 的配置。2160p
rk3576 平台在vendor/rockchip/common/vpu/etc/media_codecs_c2_rk3576.xml 下

报错分析如下：
exp: 60 * 0.95 = 57 act：26.9 测试实际能达到的fps = 26.9 / 0.95 = 28.3 28介于25和30之间，若想测试通过且符合谷歌标准，performance-point-3840x2160的value需改成25

第二个问题： testPerf
跟踪下源码可以发现
testPerf是CTS 中针对视频编解码器性能的测试方法，主要验证：
-
视频编码器在指定参数（分辨率、帧率、B帧数量等）下的性能表现（FPS）
-
解码器输出的图像质量（RMS误差）
-
是否符合
VideoCapabilities和CodecCapabilities声明的能力（如支持的分辨率、帧率、色彩格式等）
调用关系是 testPerf 调用 perf ，在调用 doTest 在这里面做核心处理。
测试的结果是：
| android.video.cts.VideoEncoderDecoderTest#testPerf[video/x-vnd.on2.vp8_c2.android.vp8.encoder_640x360_0] |
fail

java.lang.AssertionError: Expected achievable frame rates for c2.android.vp8.encoder video/x-vnd.on2.vp8 640x360: [130.0, 136.0].

根据报错信息可知，配置的是[130,136]，实际测试才[45.4609736934789，54.4713543799203] ,说明原来的配置偏大，需要重新配置，将实际测试结果包含进去即可。可配置[45,55]
找到 c2.android.vp8.encoder 配置信息，修改即可。
