FFMpeg Concat Filter - Setting start position for file
9 avril 2014, par Joyce BabuI want to concat two video files using the
concatfilter. The first file has to be included fully, whereas the second video must be included from the 10th second. Do I need to first create an intermediate file starting from the 10th second, or can I do it in one step ?The command I am using is
/usr/local/bin/ffmpeg -i intro.mp4 -i input.mp4 -filter_complex '[0:v] scale=720:576 [in1]; [1:v] scale=720:576 [in2]; [in1][in2] concat [v]; [0:a][1:a] concat=v=0:a=1 [a]' -map '[v]' -map '[a]' output.mp4I tried specifying
