![编辑剪辑后,我无法与 ffmpeg (concat) 视频合并 -- Timebase/DTS](https://linux22.com/image/1541426/%E7%BC%96%E8%BE%91%E5%89%AA%E8%BE%91%E5%90%8E%EF%BC%8C%E6%88%91%E6%97%A0%E6%B3%95%E4%B8%8E%20ffmpeg%20(concat)%20%E8%A7%86%E9%A2%91%E5%90%88%E5%B9%B6%20--%20Timebase%2FDTS.png)
我有几个视频文件想要合并在一起,在加速了一段 2 分钟的视频后(这段 2 分钟的视频很无趣,但加速后就没问题了,而且不会失去连续性。)当我尝试将编辑后的文件与其他文件合并时,失败了。以下是错误的示例。
[mp4 @ 0x103b180] Non-monotonous DTS in output stream 0:0; previous: 22228547, current: 7750549; changing to 22228548. This may result in incorrect timestamps in the output file.
发出此命令时出现此错误:
ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4
我刚刚发布了这个:
ffprobe -select_streams a -show_entries stream=time_base -of compact=p=0 newout8.mp4
输出如下:

这是我需要合并(concat)的文件之一。我使用了:

据我了解,我需要重新编码短片 (newout8.mp4),然后文件才能很好地合并。此外,ffmpeg 确实输出了一个文件,但播放无法正常进行。

正如您上面看到的,我通过将其限制为合并 3 个文件(2 个未编辑的文件和中间的已编辑文件(out8speed3))缩短了错误。
我尝试发布整个错误信息,但是对于 30,000 个字符的帖子限制来说,这太多了(如上所述)。
这是新编辑的 ffprob(我将音频比特率更改为 127k,就像其他文件一样,在将剪辑从 2 分钟加速到 15 秒后。)

答案1
新$ ffmpeg -i newout8.mp4 -video_track_timescale 90000 -strict -2 newout8speed3.mp4
修复了文件。
我在这里找到了这个: https://stackoverflow.com/questions/31691943/ffmpeg-concat-poduces-dts-out-of-order-errors
我能弄清楚他们正在谈论 tbn 值。我说的是 90k,而不是 90000,这让我更难弄清楚。
事实证明,我的视频需要转换为 90000,就像另一篇文章中所说的那样。
