【调试技巧】VPU硬解码时间打印和FAQ

Carlos 发表于 2020-1-3 15:36
我又执行了一下程序，它报的信息是这样的：
[358813.708211] rk_vcodec: vpu2_enc task: 3 ms
[358813.71 ...

你是enc,显然不对。

sudo echo 0x0100 > /sys/module/rk_vcodec/parameters/debug
bash: /sys/module/rk_vcodec/parameters/de ...

加sudo,...............

这样就可以查看是硬解码以及解码时间了

FFmpeg拉取rtsp流，送入到mpp进行解码，解码后的yuv播放正常，为啥解码时间输出为0呢？而且解码过程中cpu占用率还是很高，

同问，问题解决了吗，

我也出现这个问题了，莫名其妙的问题，突然解码就不行了。
请问怎么解决啊？

这两个log都不是错误log，都是正常的

好的，多谢。
这个 log，表示什么意思，在哪里能看到相关的资料啊。

我在解码的时候cat /proc/kmsg 显示如下

1. <3>[18407.492275]  rk_vcodec: vpu_service_ioctl:2138: error: unknow vpu service ioctl cmd 40086c01
