ffmpeg-文件名编号似乎会产生错误

这是在 Windows 10 上，我在同一个文件夹中有 3 个文件，名称如下：

  • 测试-0.数据
  • 测试-1.数据
  • 测试-2.数据

上述文件将使用 rawvideo 选项读取，然后保存为 mp4。我的 cli 命令如下：

ffmpeg -f rawvideo -pix_fmt nv21 -s 640x480 -r 15 -i test-%d.data out3.mp4

但我收到以下错误：

test-%d.data: No such file or directory

如果我尝试使用目录中的单个文件，它可以正常工作：

ffmpeg -f rawvideo -pix_fmt nv21 -s 640x480 -r 15 -i mike-1.data out4.mp4

我在这里不知所措，我可能做了一些愚蠢的事情。有人可以帮我纠正我的 cli 命令吗？

以下是完整报告：

答案1

%d或顺序模式语法%0Nd仅用于某些复用器（解复用器），例如图像文件解复用器。此模式不能与任何任意输入一起使用。

要连接原始视频，您可以使用concat 协议：

ffmpeg -f rawvideo -framerate 15 -video_size 640x480 -pixel_format nv21 -i "concat:test-0.data|test-1.data|test-2.data" output.mp4

答案2

留下双重省略号，它有特殊含义。

ffmpeg -f rawvideo -pix_fmt nv21 -s 640x480 -r 15 -i test-%d.data out3.mp4
