推荐答案

我见过的最好的工具是FFMpeg(或Libav).您可以通过一个单独的过程启动应用程序并获取框架，这是一件微不足道的事情，或者将.NET包装器用于开源库.请查看我过去的答案:如何在C#中将图像转换为视频 [

The best tool I ever saw is FFMpeg (or Libav). You can launch the application is a separate process and get frames, which is quite a trivial thing, or use the .NET wrapper for the open-source library. Please see my past answer: how to convert image to video in C#[^].
