Comment (by maxvgi):

 The input file was created from ip-camera with
 {{{
 ffmpeg -rtsp_transport tcp -stimeout 30000000 -i rtsp://.... -copytb -1
 -vcodec copy -an -map 0:0 -f segment -segment_time 30 -segment_format mp4
 out_%d.mp4
 }}}

 My camera output stream options allow setting only fixed fps, but some
 frames where possibly lost during network transmission or by camera
 hardware.
