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
}}}
