I run the following command to concatenate video clips that come straight out of my camera (my camera breaks them down into 4GB files).

ffmpeg -safe 0 -f concat -probesize 256M -i input-files-to-combine.txt -vcodec copy -acodec copy merged-P7260155-170.MOV

I receive the following errors:

Stream #1: not enough frames to estimate rate; consider increasing probesize

Non-monotonous DTS in output stream 0:1; previous: 27004416, current: 27002976; changing to 27004417. This may result in incorrect timestamps in the output file.

Any ideas on how I can solve this problem or should I just ignore these errors?

  • If the playback seems fine, ignore them.
