CamX在HAL中输出帧率日志打印

在高通CamX中,如何从HAL角度看输出的帧率呢?

打开log

将如下两行setting添加到camxoverridesettings.txt中。

enableFPSLog=TRUE
logPerfInfoMask=0x10000

然后

  • 执行adb push camxoverridesettings.txt /vendor/etc/camera/camxoverridesettings.txt
  • kill掉camera hal进程,因为修改camxoverridesettings需要camera hal进程重启才能生效

过滤日志查看FPS打印

然后搜索:CalculateResultFPS

logcat |grep -i CalculateResultFPS

日志输出如下,每10秒打印一次log:
