FFmpeg 无法读取现有的 .bmp 帧序列来制作 .avi 文件；怎么了？

Question

假设当前目录包含 .bmp 格式的文件，名为 IMG_0000.bmp、IMG_0001.bmp 等。我需要用它们制作 avi 文件，将它们当作框架来威胁。 FFmpeg 给我一个错误，我不明白出了什么问题。我收到以下错误消息:

错误消息说 ffmpeg 找不到您的输入文件序列。

他们是怎么编号的？如果它们被命名为“IMG_0001.bmp”等......你必须使用:

 fmpeg.exe" -r 4 -i d:\WORK\MyFrames\IMG_%04d.bmp -vcodec h264 -y out.avi
