FFMPEG-在视频中添加暂停

是否可以使用ffmpeg在视频文件中添加多个暂停？示例：我想从第5秒开始添加3秒的暂停，然后从第17秒开始添加8秒的暂停。音频文件同步不是问题，只是应该在指定的时间间隔暂停。

谢谢。

将循环过滤器与时间轴编辑“启用”参数结合使用。 应该允许您创建一个过滤器，该过滤器循环单个帧3秒，但仅当输出时间戳在3到5秒之间时才启用

如果我之前的回答不起作用，您可能需要剪切源视频，然后将其覆盖在空白画布上。使用-filter\u复杂参数传入构造的filtergraph

这将为您提供第一个场景

the 'concat' filter will allow you to join the scenes together

you can also use 'select' (see ffmpeg timeline editing)
to exclude the first 3 seconds of the source video for the second scene.
(You may need to import the same source video file twice
 so you can reference it as [0:v] to make the first scene 
 and [1:v] to make the second scene in the filtergraph if you run into problems.)

一个实际的、可用的示例命令将非常有助于更好地回答这个问题。
