1 × A character LCD display The most common is 1602. 0802 and 1604 would work too. In fact we are going to use 4x2 area. I do not recommend LCD I2C units. They are significantly slower when it comes to display update rate.
1 × An Arduino compatible board. Virtually any board which is capable of driving an LCD display would do. The most critical parameter for this project is flash memory. The more the better. Video streams consume a huge amount of memory. Arduino UNO is a good choice to start. But Mega or even ESP32 would allow you to process longer videos.
