Video Processing, Video Analytics, Image Detection, Image processing

I am looking for someone with experience in video processing and image detection.

I would like you to make a script to retrieve specified information such as kill count, remaining life, weapon information, character information, etc.. from FPS gameplay videos.

The video is long, so I would also like to get the game status and what screen they are looking, such as main screen, character selection screen, in game, etc..

I think there will be other video-related processes as well. ( video split, GUI )

You can do it with or without machine learning. Please describe how you will achieve this, along with the language you will use.
