  1. 用 echo 0x100 > /sys/module/rk_vcodec/parameters/mpp_dev_debug,然后跑测试,如果用了硬解码,会有内核打印每个任务的时间
  2. 新的内核补丁会加上使用率

那如何关闭显示呢?echo 0x00 > /sys/module/rk_vcodec/parameters/mpp_dev_debug 不生效;屏显信息太多了

echo 0 应该是能生效的,估计是路径打错了

但是我这边仍然是未生效的欸,路径是/sys/module/rk_vcodec/parameters/mpp_dev_debug没复制错;logcat抓取仍然屏显rk的解码信息
