 How to reproduce:
 {{{
 % ffmpeg -y -f concat -i l.txt -c copy  -bsf:v h264_mp4toannexb
 output.mkv
 ffmpeg version 2.7
 }}}

 Hi,
 I have create 2 files with:

 ffmpeg -i in1.mkv --ss "somewhere" -to "here" -c copy 1.mkv
 ffmpeg -i in2.mkv --ss "somewhere" -to "here" -c copy 2.mkv

 the file "l.txt" contain :
  file '1.mkv'
  file '2.mkv'

 When i play out.mkv, the av sync is good in the first party (corresponding
 to 1.mkv) but not good at the seam between the 2 videos if i let play it.
 When press forward-seek then av is again sync.
