相机Camera日志分析之三十一：高通Camx HAL十种流程基础分析关键字汇总（后续持续更新中）
【关注我，后续持续新增专题博文，谢谢！！！】
上一篇我们讲了：有对最普通的场景进行各个日志注释讲解，但相机场景太多，日志差异也巨大。后面将展示各种场景下的日志。
通过notepad++打开场景下的日志，通过下列分类关键字搜索，即可清晰的分析不同场景的相机运行流程差异，日积月累这样将能快速提升分析日志的能力。
这一篇我们开始讲： 相机Camera日志分析之三十一：高通Camx HAL十种流程基础分析关键字汇总（后续持续更新中）

十一、：录像日志关键字
一、背景
1：【效率决定成长空间】无论什么开发，分析日志是解决问题的法宝。且是最有效最常用的调试工具，特别是在Android或Linux领域下，log分析是开发必备技能，然而log分析效率参差不齐，你分析一份日志要一天，别人分析只需要一个小时，作何感想？别人一年的学习成果可能是你几年才能学会。
2：【巨量日志降低了开发效率】接触过Android日志，就清楚日志量非常大。几十个进程几百个线程同时并行打印日志。而Camera领域日志量极大，因为预览一般是每秒30帧的日志量，录屏一般是每秒60帧的日志量，少则几万行日志，多则几十万行日志，更多则多个日志总量几百万行日志。
3：【日志梯度分级来提效】开发追求效率，如何快速有效挖掘出问题，并如何解决问题变得尤为重要。此专题将以梯度分级日志来分析日志，让日志流程变得简单化，提高解决问题的效率。
4：【举一反三】当前以高通CamX架构为例讲解Camera日志，方式通用，其他领域模块均可效仿借鉴。
5：【开发思维决定成长高度】当前讲述的是Camera领域log分析梯度分级讲解，讲究的是一种分析技巧，分析思维，一种感悟。技术路线的提升空间，需要更多开发技巧和开发学习能力去提升。技术大拿分析问题，可以从日志快速定位问题并解决问题，有充分的时间去学习更多知识，成长速度极快。同一起跑线，学习能力，开发效率等等都决定了程序员的成长提升空间。记得我毕业三年，同学之间的差距无限拉大，一些人还在几千块薪水，你已经是他的四五倍了，人与人的差距就是短短几年就拉开了。
