文件地址有误，之前通过

[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/camera_movie"];

获取沙盒Documents目录，想要将录制的存放在对应路径下。但是一直报-11800 错误。

但是在不断尝试之后，发现改文件名是没有用的，主要是文件路径问题，有一种方案能够解决当前问题，就只把视频文件存放到沙盒目录下Library/Caches文件中。

[[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:@"camera_movie"];

文件路径就可以使用了file:///var/mobile/Containers/Data/Application/ADA3EA2F-D872-4E66-8371-01D66F4453CB/Library/Caches/camera_movie
