I want to play video from SD card by using arduino mega 2560 and TFT 3.2" touch screen is it possible ?
if yes please tell me.
thanks in adavance

An ATMEGA2560 has no enough computational power to perform on-the-fly decoding, even at resolutions as low as 160x128 pixels and low frame rates.
The best you can hope for is a 20 fps, 16 bpp, 160x128 pixel video, directly streamed from the SD card, uncompressed (800kB/s), if the MCU runs at 16MHz. Even with such low specs, you'll have to use a trick, to implement a direct peripheral to peripheral transfer.
We made a guide here for the Arduino Uno (i.e. ATMEGA328P), but it should work also for ATMEGA2560 with little modifications: https://next-hack.com/index.php/2017/08/14/how-to-play-a-video-on-arduino-uno-46-playing-a-20-fps-animation-from-sd-card/
On the same link you'll find also the youtube links for a video guide.
