//merge videos
To merge files together using ffmpeg:
1. make a textfile.txt with the list of files you want to merge:
file '1.mp4'
file '2.mp4'
file '3.mp4'
2. Then input this command into terminal
//doesnt work
ffmpeg -f concat -i <textfile.txt> -c copy -fflags +genpts merged.mp4
ffmpeg -f concat -safe 0 -i textfile.txt -c copy merged.mp4
//zoom in videos
ffmpeg -i PA190747.MOV -strict -2 -vf "scale=2*iw:-1, crop=iw/2:ih/2" KALIA2.mp4
//CONVERT
ffmpeg -i KALIA4.MOV -vcodec mpeg4 -acodec ac3 -ar 48000 -ab 192k KALIA4.mp4
//put videos together
//partly working

-map "[v]" -map "[a]" -ac 2 together.mp4
//reverse video

ffmpeg has a reverse filter.
For video only:
ffmpeg -i /storage/emulated/0/ffvid/frameCount.mp4 -vf reverse reversed.mp4
For audio and video:
ffmpeg -i KALIA1.mp4 -strict -2 -vf reverse -af areverse reversed.mp4
This filter buffers the entire clip. For larger files, segment the file, reverse each segment and then concat the reversed segments.
