Add FFmpeg to your project

Add library: FFmpeg (for GCC: -lavformat -lavcodec -lavutil -lswscale -lm -lz -lpthread)

Usage

Enable LV_USE_FFMPEG in lv_conf.h.

See the examples below.

Note that, the FFmpeg extension doesn't use LVGL's file system. You can simply pass the path to the image or video as usual on your operating system or platform.
