Convert 180º panoramic video source to equirectangular

Dear All,
I have a request to know if someone can help me for a job and I think it may interest many people.

I am looking for a way to convert the video image of a panoramic device (180º) to the most rectangular possible (equirectangular), specifically a football field.

I have already tried with the fisheye plugins, Shaders, 3D, etc... but the results are not what we expected.

I've used the Hugin editor and surprisingly, using the Move/drag option, it's enough to just curve the ends so it's pretty flat.
For this it uses three axes: Yaw, Pitch, Roll.
By modifying the Pitch, the image maintains the proportion in the center but the ends rise like a horseshoe, creating a straighter horizon.

I think there is some software that does this automatically or by drawing the game rectangle and I think applying some tri-source stitching.
Could this be emulated?

For the moment ...
Is there someone who can convert this process to a plugin or rewrite the .txt of fisheye.shader?

Many Thanks in advanced.
