推荐答案

您的问题很安静...
以下示例可能会对您有所帮助，但可能无法解决您的特定问题.

You question is quiet general...
The following example may help you, but it might not solve your specific issues.

该示例适用于三个阶段:

The example applies three stages:

• 创建合成视频(无音频):

• Create synthetic video (with no audio):

ffmpeg -f lavfi -i testsrc=duration=3:size=160x120:rate=10 -c:v rawvideo -pix_fmt rgb24 testsrc.avi

(创建的视频未压缩).
参考: https://trac.ffmpeg.org/wiki/FilteringGuide

(The created video is uncompressed).
Reference: https://trac.ffmpeg.org/wiki/FilteringGuide

将视频分为3部分(创建3个视频文件):

Cut video into 3 parts (creating 3 video files):

ffmpeg -i testsrc.avi -ss 00:00:00 -c copy -t 00:00:01 sec0.avi
ffmpeg -i testsrc.avi -ss 00:00:01 -c copy -t 00:00:01 sec1.avi
ffmpeg -i testsrc.avi -ss 00:00:02 -c copy -t 00:00:01 sec2.avi

参考: https://superuser.com/questions/138331/using-ffmpeg剪辑视频

以相反的顺序串联(合并)3个部分:

Concatenate (merge) 3 parts in reverse order:

ffmpeg -i "concat:sec2.avi|sec1.avi|sec0.avi" -codec copy output.avi

注意:对于Linux，请使用单引号'
参考:使用ffmpeg连接两个mp4文件

Note: for Linux use single quotes '
Reference: Concatenate two mp4 files using ffmpeg

合成视频如下图所示:

Synthetic video looks as the following image:
