image-processing - ffmpeg 只处理第一张图片

Question

我有一个 .png 图像的目录（我之前曾尝试过 .jpg，直到我在某处阅读 ffmpeg 更喜欢 .png）。

图像共享文件编号格式 cof000.png - cof358.png。

我想将这些图像转换为动态图片格式。MPG 或 MP4 都可以。

我试过的命令是

ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4

我改编了这篇文章中的命令，在这里：

https://stackoverflow.com/questions/53778503/ffmpeg-video-slideshow-only-takes-first-image

即使在尝试了许多不同的命令排列之后，最终文件中也只有第一个图像。我正在使用窗户。

我需要在 Windows 上使用什么 ffmpeg 命令将所有 180 个图像文件编译成单个运动图像？

这是使用命令的输出：

$ ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4
