使用android

Question

我想用FFmpeg连接MP4视频，问题是当我想合并用Iphone和Android拍摄的视频时会引发问题：

  

输出流0：1中的非单调DTS;上一篇：150528，当前：139268;更改为150529.这可能会导致输出文件中的时间戳不正确。

这是我的代码

merge.txt

file 'iphone.mp4'
file 'android.mp4'

FFmpeg命令

ffmpeg -f concat -i marge.txt -c copy -y merge.mp4

如果我无法合并此视频，我怎样才能使用相同的参数（帧速率，比特率......）制作它们并将它们合并？

我使用FFmpeg版本2.4.2，因为我找不到比FF.2更高的android FFmpeg库。

这是完整的控制台输出：ffmpeg -i android.mp4 -i iphone.mp4
