x264 [info]: using cpu capabilities: ARMv6
6410硬比armv6t2更高一个档次的才对。他有trustzone什么的。

但是armv6t2下编译不错，应该是我用的三星官方的编译器的问题。
armv6可以过。说明确实只是支持armv6.
那其他的那些特殊的指令呢，能支持么？
反正contex的选项， 编译器绝对是不支持的。
编译不过，应该是编译器的问题，也许我应该在后续工作中，使用更高版本的编译器。

下面的这个是realboard的那个x264，lxzhang大牛编译的：

不带有asm编译的，三星官方编译器编译的版本的运行结果在这里。

x264不太懂，不太明白是不是性能提升很明显。
