当图像不是连续的时，有没有办法在 ffmpeg 中输入多幅图像？
就像是-i image1.jpg otherimage.jpg newimage.jpg？
我知道如何使用-i img-%3d.jpg，但这不适合我的需要。
occvtech 的答案结果是 1 张图片

答案1
我个人总是发现重命名目录中的文件更容易，这样它们是连续的（在 Windows 上 - 突出显示所有文件，然后按 F2 重命名）。
但是，如果由于某种原因您想要手动输入三个 jpg 文件（名为 image1.jpg、otherimage.jpg 和 newimage.jpg），您可以单独使用该-i标志来完成。
ffmpeg -i image1.jpg -i otherimage.jpg -i newimage.jpg ....
