编辑剪辑后，我无法与 ffmpeg (concat) 视频合并 -- Timebase/DTS

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：

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'newout8.mp4':

这是我需要合并（concat）的文件之一。我使用了：

ffprobe -select_streams a -show_entries stream=time_base -of compact=p=0 out7.mp4

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'out7.mp4':

    Metadata:

time_base=1/48000

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。
