[FFmpeg-user] Help with error: "Non-monotonous DTS in output stream"

[avirex]

Hello.

I am re-streaming a Live H264/AAC stream using ffmpeg (windows).  After
about 1 hour I'm getting the following error in the console:
 
Non-monotonous DTS in output stream 0:0; previous: 38226576, current:
31954543; 
changing to 38226576. This may result in incorrect timestamps in the output
file.

Here is the command I am using:

ffmpeg.exe -threads 0 -i "$rurl playpath=$rplaypath swfUrl=$rswfurl
pageUrl=$rpageurl live=1 " -map_metadata -1 -loglevel info -f flv -acodec
copy -vcodec copy -r 15 -aspect 16:9 -bufsize 12000k
"rtmp://localhost/$dapp/$dstream"  2> F:\Streams\$dstream.log
 

Any idea what this error message means and how to mitigate?  Here is a bit
more detail from the log, when the error actually starts...

negative cts, previous timestamps might be wrong

changing to 4423587. This may result in incorrect timestamps in the output
file.


So you can see at that point the the DTS/PTS status message is completed
replaced by the "Non-monotonous DTS" error.  Also notice the "current" value
is negative and then climbs back to positive value.


Thanks for any insight.
