I if understand right your goal, you should take a look at Avisynth. I use it -and like it. It's for Windows only, but conceptually it seems to have what you are going after: a script language for non-linear video editing.
I'm having trouble understanding the purpose of writing such code.
If you are intending on creating a tool that a user can use to edit a video by supplying a set of commands, how is forcing the user to write text better than the GUI video editors that are available? Its going to have a pretty low usability in this situation.
If you are looking for a way to automate some kind of editing process, some video editors like VirtualDub already contain tools for batching and plugins to allow them to be automated.
Are you actually looking to make a tool that will be used by someone to edit video or is this for your own intellectual curiosity?
When it comes to writing video editing software, I always see ffmpeg mentioned.
From the site:
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec - the leading audio/video codec library.

我如果正确理解您的目标，您应该看看 Avisynth。我使用它并且喜欢它。它仅适用于 Windows，但从概念上讲，它似乎拥有您想要的东西：用于非线性视频编辑的脚本语言。

我无法理解编写此类代码的目的。
如果您打算创建一个工具，用户可以通过提供一组命令来编辑视频，那么强制用户编写文本如何比可用的 GUI 视频编辑器更好呢？在这种情况下，它的可用性相当低。
如果您正在寻找一种自动化某种编辑过程的方法，一些视频编辑器（例如 VirtualDub）已经包含批处理工具和插件，以允许它们自动化。
您是否真的想制作一个供某人编辑视频的工具，或者这是出于您自己的求知欲？

最好的起点是安装常见视频编辑软件的试用版，然后看看它们提供什么功能。
The best starting point can be installing trial version of the common video editing softwares and see what they offer.
当谈到编写视频编辑软件时，我总是看到提到ffmpeg。
