Is there multiple types of transitions in ffmpeg while merging two or more videos?

Question

I have 3 video files. I am using ffmpeg library to merge them all.

While merging them right now I am using fade In/Out transitions only.

I want to enhance that feature in my site, can I do transitions like diamond, circle and some other possible transition effects.

Here is the reference urls
