I want to show a film clip with some data on TFT LCD.How to do it?
Connect the monitor to a PC. Then play the film clip.
Not using a PC? Then, you will obviously have to figure out a number of things yourself: - is the hardware fast enough? - does the hardware have a hardware interface suitable for interfacing a LCD? - does the hardware run any operating system that incorporates support for a frame buffer, and for accelerating the decoding of the video? - does the hardware require you to directly access the LCD "graphics card", or is there a driver library? - ...
It's really only with a PC, Mac, ... that you have standardized ways to play film clips. And you have provided us with zero information about your hardware or your actual needs.
