运行mpi_dec_test解码h264裸流文件花屏

[wangbinfei]

我是在toybrick板子rk3399prod上debian10上编译的mp.当我运行mpi_dect_test时，解码得到的yuv是花屏甚至绿屏。以下下是mpi_dec_test的结果

请问大佬们，这个是哪里出错了呢，为什么运行mpi_dec_test会不成功，debian10 kernel: [18349.105688] rk_vcodec: vpu_service_ioctl:2140: error: unknown vpu service ioctl cmd 40086c01是什么严重错误码

unknown vpu service ioctl cmd 40086c01 这个可以忽略，这时内核版本检测时候的一个打印，旧内核+新mpp的时候会出现 这个内核是 4.4 版本的，比较旧了。 从 log 上看，并硬件并没有报错出现，是否是数据保存方面出现了问题？

多谢了大佬，问题解决了，保存也没问题。之前不了解yuv，然后学习了，最后意识到原来是yuvplayer播放yuv文件的时候没有设置正确分辨率。。。
