For example, consider checksums. If a file format contains a checksum, then you simply modify the checksum so it matches your random data before passing the file to the application.
例如，考虑校验和，如果文件格式包含一个校验和，在将文件传至应用程序前仅仅修改此校验和就可以使其同随机数据相匹配。
As is well known, pure video stream only can be played orderly, and can't be random accessed or played in network. File format is designed to solve these problems.
视频流本身只能顺序播放，不能进行随机访问和网络流化播放，文件封装则是为解决这些问题而设计的。
