自己本机测试最快时60帧/秒,局域网传输只测试一次,结果很让我失望,原因不明~~~~
说下我的思路过程(我认为过程很重要!)
分块比较+压缩传输与以前那个内存流比较的优缺点:
内存流比较能找到最精确的找到图片差异,但每次都要压缩相同大小的数据,大家可以测试下,那个算法传输瓶颈是压缩算法,最费时间和CPU
分块比较+压缩传输能有效的减少压缩数据量,但缺点也很明显,比较图片的效率肯定没内存流比较高,要加快传输只能找到更好的算法
我选择的是后者,开始的时候是直接把截下来的图片分成n块,然后逐块和上一个图片比较,不同就放到流中压缩传送,不过写完测试时很是郁闷,Cpu占用不说,在自己电脑上根本就突破不了16帧,当时就苦想能节约时间的方法(当时做梦都在想^.^),终于在一次被吵醒后来了灵感,每次都要把图片分成n块,这也很占时间啊,有没有更好的办法呢?觉也睡不着了...
具体实现就看代码吧^_^-Their own tests of this machine, when the fastest 60 fr a mes/sec, LAN transmission test only once, the result will let me down, for reasons unknown ~ ~ ~ ~ wrote down my thought process (I think the process is very important!)
