Comment (by cehoyos):

 Assuming you have two input files {{{input1}}} and {{{input2}}}, the
 following two commands are completely equivalent:
 {{{
 $ cat input1 input2 >input
 $ ffmpeg -i input
 }}}
 {{{
 $ ffmpeg -i "concat:input1|input2"
 }}}
 The advantage of using the concat protocol is that it saves you one line
 and the space for {{{input}}} on your harddrive. If the first command does
 not work because the container does not support concatenation, the second
 will also fail.

 Please understand that this is a bug tracker, not a support forum, see
 https://ffmpeg.org/contact.html and https://ffmpeg.org/ffmpeg-
 formats.html#concat-1 and https://ffmpeg.org/ffmpeg-filters.html#concat
