Comment (by Krieger):

 Sorry for delay.
 Made a dump.mkv file
 (https://dl.dropboxusercontent.com/u/43104344/dump.mkv), taken this way:
 {{{
  $ ffmpeg -loglevel debug -f mjpeg -use_wallclock_as_timestamps 1 -i
 'http://user:password@host/mjpeg.cgi' -codec copy trendnet_rtp/dump.mkv

 The issue is indeed reproduced if you stream RTP this way:
 {{{
 ffmpeg -re -i trendnet_rtp/dump.mkv -loglevel debug  -vcodec copy -f rtp
 rtp://127.0.0.1:6666
 }}}
