ffmpeg gives error DTS out of order and Non-monotonous DTS in output stream [migrated]
16 août 2015, par tmoore82I’m trying to concatenate multiple mp4 videos into one using ffmpeg. The "how to" for this is mostly identical across the web :
ffmpeg -f concat -i inputfile.txt -c copy output.mp4But when I try to concatenate my files, I keep getting output like the following :
[concat @ 0x1f72560] DTS 3815 < 3812809 out of order
[mp4 @ 0x20ad2e0] Non-monotonous DTS in output stream 0:0; previous: 3812809, current: 3815; changing to 3812810. This may result in incorrect timestamps in the output file.The result is that I have a file where the audio and video work for the first segment, but only the audio works for subsequent segments. Occasionally, I’ll get a video with no audio.
Some users switch to MP4Box, but I’ve tried MP4Box with the same results. What am I missing ? I saw this post that says
-c copyis the problem, but I don’t really follow what it’s saying about reencoding or why that’s necessary.Command :
ffmpeg -f concat -i test.txt -c copy test.mp4 &> result.txtContents of
test.txtfile '/raw/01 - Introduction.mp4'
file '/raw/02 - Background Material.mp4'Contents of
result.txt: http://paste.ubuntu.com/12101801/ -
