Image Magick 有效吗？它是一个非常强大的 C++（和 C）绑定库。它确实支持从某些视频格式中抓取静止帧，请参阅此处。这是一个命令行示例，但也应该可以通过 API 运行。
Will Image Magick work? It is quite a capable library with C++ (and C) bindings. It does support grabbing still frames from some video formats, see here. It's a command-line example, but should work from the API as well.
