I love Termux, I use it every now and then. ffmpeg is the one I use the most on it, best solution to trim videos, reduce size.
ffmpeg -i video.mp4 -s 0 -t 30 out.mp4
cuts video.mp4's first 30 seconds into out.mp4 with perfect audio sync. (status ഇടാൻ :p)

The command line? Who the heck uses that anymore? And certainly not on a cell phone. /s

I also use youtube-dl in it to download Instagram reels, youtube videos etc. etc.
wget -c -d -O "http://file.zip" to resume-download files.
Also used it for cowin vaccine booking automation script made by a Malayalee specifically for termux.
Many usecases !
