常用MIME类型(Mp4的mime类型设置)
前两天在遇到了一个h5写的mp4视频网页在某些电脑中打开后只下载而不播放的问题（大部分电脑都播放正确，而有些电脑在打开网页时就会变成迅雷下载，下载完成也不会播放）。
html如下：
后来发现是服务器MIME配置有问题， 原来服务器配置的MIME type为：application/octet-stream。改为video/mp4之后就好了。
那么，application/octet-stream和video/mp4有什么区别呢？
1、先看一下mime type的定义，维基百科中的解释很好，特此摘抄过来：
一个MIME类型包括一个类型（type），一个子类型（subtype）。此外可以加上一个或多个可选参数（optional parameter）。其格式为
类型名 / 子类型名 [ ; 可选参数 ]
目前已被注册的类型名有application、audio、example、image、message、model、multipart、text，以及video。chemical是一个非官方的常用类型名。[1]此外，非标准的类型名一般会加上x-前缀，但这种做法已经过时。[2]
子类型名通常是一个媒体形式被冠以的名称，不过子类型名中也会有其它信息，包括厂商信息、产品信息、分类信息（子类型会被归进一个树状的分类结构中）、后缀等等。树结构分类信息以被.相互连接的字符串表示。每一个由.分隔开的部分又可以加上与其以-相连接的附加信息。此外，子类型名中也会有放在最后，与前面的内容以+相连接的后缀。因此，一个媒体类型的格式可以被更加细地表示为：
类型名 / [ 树结构分类信息（中间可能有一个或多个“.”） ] 子类型名（中间可能有一个或多个“-”） [ + 后缀 ] [ ; 可选参数 ]
2、再看看这两种的类型的用途：
application/octet-stream:任意的二进制文件（通常做为通知浏览器下载文件）；
video/mp4：MP4视频文件[RFC 4337]
