【问题描述】:
我有三个视频,我想将它们连接在一起问题它适用于某些视频但当我测试特定视频时它给我一个错误并导致生成的视频以一种奇怪的方式显示并且一切都进展得非常快在视频中,就像我转发视频一样
这是我用来从 out.txt 文件中添加视频的代码
file 'D:/Build/start.mp4'
file 'D:/Build/a.mp4'
file 'D:/Build/Song & Lyrics/2f.mp4'
我在 ffmpeg 中使用的命令
ffmpeg -f concat -safe 0 -i out.txt -c copy -y go.mp4
我遇到了这个错误

那么是什么问题导致了这个错误。当我使用这个新的 start.mp4 与我在其他视频上尝试过的视频合并时出现问题。
更新
我测试将视频转换为 MTS 格式,然后将它们连接为类似问题的答案,但问题是当我将 mp4 视频转换为这种格式时,文件的大小从 6 MB 到 42 MB 太大!所以如果有更好的答案。或使文件大小保持不变或更小的方法
答案的链接是here,但效果很好
在此先感谢
【问题讨论】:

我意识到这是旧的,并且已经有了答案(与 OP 相同)。这根本不是编程问题。
-
我知道它不是 :),我标记了视频和 ffmpeg,我认为这个问题很清楚,一个 ffmpeg 问题是的,关闭它,很长时间了:D
