           Summary: /usr/bin/avconv: encoding with libmp3lame and -ar set
                    aborst on invalid, non monotonically dts
           Product: Libav
           Version: 9
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: libavformat
        AssignedTo: bugzilla at libav.org
        ReportedBy: siretart at tauware.de


Bug forwarded from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=692876



avconv fails to encrypt my test.avi (attached) when I use the libmp3lame and
set -ar as in the
example below. Setting it to 16000 as the input works. Using an other codec,
e.g. libvo_aacenc
also works.

[avi @ 0x1f6a5a0] Application provided invalid, non monotonically increasing
dts to muxer in stream 1: 37 >= 37
av_interleaved_write_frame(): Invalid argument
