I manage to download all the files (init file + 10 segment files) and put them in an array


File[] files = downloadSegments();


So I have :
[0] -> file-0.m4v (which is the init file)
[1] -> file-1.m4v (1st segment)
... and so on.


My question is how can I concat/append all these files into another file (final_segment.m4v) ?


I looked around a lot and am now using 'com.arthenica:ffmpeg-kit-video:4.5.1-1'
I've last tried :


FFmpegSession session = FFmpegKit.execute("-i file-0.m4v -i file-1.m4v ... -c copy final_segment.m4v");



Is there something I'm missing ?


Also I assume that I'll have to do the same for the audio segments. So I will have 2 files (final_segment.m4v and final_segment.m4a) that I will have to merge/mix together.


If you could help me with some piece of code, that would be great.
