Comment (by cehoyos):

 Here is another alternative (using the concat filter) that allows to
 concatenate the files and keep A/V sync (thanks to Clément Bœsch for the
 example):
 {{{
 $ ffmpeg -i TestOrginal1.flv -i TestOrginal2.flv -filter_complex
 '[0:0][0:1][1:0][1:1]concat=v=1:a=1[v],aresample=async=1[a]' -map [v] -map
 [a] -qscale 2 outfilter.avi
 }}}
 Or an equivalent shorter command line:
 {{{
 $ ffmpeg -i TestOrginal1.flv -i TestOrginal2.flv -filter_complex
 'concat=a=1[v],aresample=async=1' -map [v] -qscale 2 outfiltershort.avi
 }}}
