最佳的Python视频处理库？ [英] Best video manipulation library for Python?
问题描述
我想为正在编写的Python应用程序提供一些简单的视频编辑功能，并使用谷歌搜索功能：
I'd like to include some simple video editing functionality for the Python application I'm writing and googling comes up with:
- pymedia
- pyglet（使用媒体模块）
- gst-python
要求：
- 占地面积小。我已经在使用 wxPython （正因为如此），它很容易膨胀最终的EXE文件，因此最好不要将我用来实现此视频编辑功能的任何内容显着增加。
- 仍应积极维护该库。
- 它不需要专有许可，因此FMOD成为不可能。
- 最小依赖项
- 不是成熟的视频编辑器。不需要花哨的裤子东西。只是能够跳到视频的不同部分，或者抓取帧或在视频部分的开始和结束处放置（多个）标记以截断位。
- 跨平台-可以在一天结束时在Windows，Linux和OS X上运行。
- Small footprint. I'm already using wxPython (just because), which bloats up the final EXE file pretty easily so preferably whatever I use to implement this video editing functionality shouldn't add to the bloat significantly.
- The library should still be actively maintained.
- It shouldn't require proprietary licensing, so FMOD is out of the question.
- Minimal dependencies
- Not a full-blown video editor. No need for fancy pants stuff. Just the ability to skip to different parts of a video and either grab a frame or put (multiple) markers for start and end of video sections to lop off bits.
- Cross platform - should be able to run on Windows, Linux and OS X at the end of the day.
如果您使用了以上任何一种上面列出的视频编辑库或我尚未在您的Python应用程序中遇到的其他视频编辑库，我想知道每种方法的陷阱以及它们之间如何相互叠加。如果您还知道avbin的Python绑定，我想知道在哪里找到它。
If you've used any of the above video editing libraries listed above or others I have yet to come across in your Python application, I'd like to know the pitfalls for each and how they stack up against each other. If you also know of a Python binding for avbin, I would like to know where to find it.
gst-python（带有Python绑定的Gstreamer）似乎没有有充分的记录。似乎也与pyGTK紧密结合，后者也是一个非常大的工具包。
gst-python (Gstreamer with Python bindings) doesn't seem to be very well documented. It also appears to be tightly coupled with pyGTK, which is also a pretty big toolkit.
推荐答案
我建议您再看一遍在gst-python上！它不是与pyGTK结合在一起的。您可以完全单独使用它，而不依赖于Python绑定或GTK的C库。我已经写了几个使用gst-python而不是GTK的命令行实用程序。
I would recommend that you look again at gst-python! It is not coupled with pyGTK. You can use it completely separately, with no dependencies on either the Python bindings or the C libraries of GTK. I've written several command-line utilities that use gst-python and not GTK.
的确是 gst-python文档不太好。但是，关于C API和模块的文档确实非常广泛，并且来自C API的映射Python API的使用非常简单。而且有一个非常活跃的Gstreamer社区，我很幸运在邮件列表和IRC上找到了帮助！
It's true that the gst-python docs are not so great. However, the documentation for the C API and modules is really very extensive, and the mapping from the C API to the Python API is very straightforward. And there is a very active Gstreamer community and I had good luck finding help on the mailing lists and IRC!
