FFmpeg support

FFmpeg A complete, cross-platform solution to record, convert and stream audio and video.

Install FFmpeg

  • Download FFmpeg from here
  • ./configure --disable-all --disable-autodetect --disable-podpages --disable-asm --enable-avcodec --enable-avformat --enable-decoders --enable-encoders --enable-demuxers --enable-parsers --enable-protocol='file' --enable-swscale --enable-zlib
  • make
  • sudo make install

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.
