[FFmpeg-user] Concatenate mp4/h264 files, some without sound track

[Tim Hiles]

in windows I use this:

c:\ffmpeg\ffmpeg\bin\ffmpeg.exe -loglevel error -f concat -i filelist.txt
-c copy %finalname%

filelist.txt looks like this

# this is a comment
file 'C:\somepath\somefile.mp4'
file 'C:\somepath\somefile2.mp4'

Seems to work fine for me.
