There was a task to create an application for Android that lets you record and work with video. There is no problem with recording video from a camera, but I ran into a problem processing videos. For example, you want to crop video, overlay audio, apply a few videos on each other ...

Are there any libraries that can help me achieve my goals? I was looking for some information on this issue, some people recommend using ffmpeg. Can ffmpeg library help me achieve what I described above?

I would be grateful for any information.

Thank you.

I would suggest the same,
FFMPEG library is the best solution available to your problem.
Its a lot it can do.

Here are few sample commands, but you'll get all of you mentioned above if your search on web.

CROP:
I dont know what do you mean by cropping,
But you can use these commands 

ffmpeg -i in.mp4 -filter:v "crop=out_w:out_h:x:y" out.mp4

for details check this

OR 

ffmpeg -i movie.mp4 -ss 00:00:03 -t 00:00:08 -async 1 cut.mp4

see details

OVERLAY AUDIO: 

ffmpeg -i input.mp4 -i input.mp3 -c copy -map 0:0 -map 1:0 output.mp4

check this
