将密钥添加到文件尾部的例子

一个x264编码的可执行程序 x264.exe，因为我只修改了 x264 的算法，未加入任何汇编，也没有修改x264的接口和功能，所以原版 x264 能运行的平台，此程序也应当能运行，且功能及调用方式不变。 执行命令方式为： -o 输出文件 输入文件 宽x高 -B 目标码率-X264 encoding an executable program x264.exe, because I only modified x264 algorithms, not to join any compilation, there is no modification of the interface and functionality of x264, the x264 can run the original platform, this procedure should also be able to run, and function and calls the same way. For the implementation of the order:-o output file input file width x high-B target rate
