            Bug ID: 1026
           Summary: concat protocol cannot be used
           Product: Libav
           Version: 12
          Hardware: X86
                OS: Linux
            Status: NEW
          Severity: major
          Priority: ---
         Component: general
          Assignee: bugzilla at libav.org
          Reporter: wyrdagarjzla at yahoo.com

I compiled myself libav V12 on my Debian 8.6 with extra support for x246 and
vpx, nothing disabled.
Now I want to use the concat protocol to concatenate some files and I get this
concat:/tmp/rec3.1_pad.mp4|/tmp/rec3.2_pad.mp4|/tmp/rec5_pad.mp4: Protocol not

command executed:  avconv -i
concat:/tmp/rec3.1_pad.mp4\|/tmp/rec3.2_pad.mp4\|/tmp/rec5_pad.mp4 -c copy
(input files are not really mp4 files, they were coded with -bsf:v
h264_mp4toannexb -f mpegts )

avconv command output:
avconv version 12, Copyright (c) 2000-2016 the Libav developers
  built on Feb  9 2017 22:30:14 with gcc 4.9.2 (Debian 4.9.2-10)
Hyper fast Audio and Video encoder
usage: avconv [options] [[infile options] -i infile]... {[outfile options]

Is something wrong with the way I use the protocol or is a bug?
