Non-monotonic DTS (Decoding Time Stamp) errors are a common problem
that occurs when processing video and audio files with FFmpeg. This
error occurs when the timestamps of the output stream are not
monotonically increasing.

When this error occurs, the timestamps of the output file may be
incorrect, and this may cause problems when playing back the file.

In any case, it is recommended that you use the latest version of
FFmpeg, as older versions may frequently encounter this error.

Possible solutions;

	 1. re-encoding

	 or

	 2. adjusting the FFmpeg options

	    2-1. -fflags +igndts: ignore timestamps

	    2-2. -copytb 1: specify how to copy timebase

However, it may be difficult to completely avoid this problem.

Best Regards.
