There are plenty of libraries like x264 to do this type of thing for you, but you'll probably need to use a library. Video encoding is not an easy task.
I'm pretty sure you can do it with ImageMagick which has been ported to the iPhone Try the 'convert' command. (I haven't done this myself, so you might need to do some research on the latest iPhone port and how to use the command.)

有很多库（例如 x264）可以为您完成此类操作，但您可能需要使用库。视频编码并不是一件容易的事。

我很确定你可以使用 ImageMagick 来做到这一点，它已经 移植到 iPhone 尝试“转换”命令。 （我自己没有这样做过，所以你可能需要对最新的 iPhone 端口以及如何使用该命令进行一些研究。）
