I'm trying to limit the log level for the process /system/bin/mm-qcamera-daemon because when the camera strats working (recording video) it generates a lot of logs similar to the following entries:

The camera works correctly, but I'm seeing high CPU usage by this process. I tried to limit the log-level of the process by using the following command but it doesn't seem to have an effect:
adb shell setprop log.tag.mm-camera CRITICAL
Any help or hints are more than welcome.
PD: The device I'm using is not rooted so I can't create the /data/local.prop file which is another alternative to limit the log level as I read on other answers.
