拒绝造轮子，所以当然要选择开源库。
由于是mtk功能机平台，只支持c，所以c++和java什么的就不考虑了。
二维码的编码，选择了qrencode，这个移植比较简单，不多说。
二维码的扫描算法，走了一些弯路。一开始根据网上的扫描算法速度对比，选择了quirc。但是移植好了实际上机测试，完全不是那回事，速度慢的要死，十几秒没反应，机器直接重启了。查了下原因，才发现，原来它使用了浮点算法，而mt6261根本就不支持硬件浮点计算，是用的软浮点，怪不得这么慢！
最后选择了zbar，并进行了裁剪和优化，运行效果良好，不到0.5秒就能完成从扫描到识别出二维码的操作。
源码就不贴出来了，外包项目，代码还是要适当保密。

Further, it is a matter of deep regret that Mr Tomlinson's family learned of the nature of his contact with Simon Harwood through the press, rather than from our officers. I fully appreciate and regret the distress this must have caused the family."

Often, gaming companies deliver these contests with an agenda, promoting a game, or a DLC, or something. But this contest feels far less corporate, and a bit more . . . personal.
