How to play a video in mirror?

Question

Mobile development

Hello.
There is a task to glue and play a video in a mirror, on android and Ios, for this I want to write a library in c ++
An approximate picture, the picture does not relate to the task in any way, I took it so as not to draw and it was clearer

What tools are better to use, what you should pay attention to was the most portable?
Thanks in advance.

Hmmm... Well, I would suggest you the following algorithm:
1. Take 1/3 of the bottom of the picture, copy it to a separate buffer.
2. In this buffer, you invert the points along the Y axis (you flip the image).
3. Do a Gaussian blur.
4. Apply "shading" according to the exponential law (minimum above, maximum below).
It seems that this effect can then be achieved.
