• How to correctly setup Linker in Eclipse IDE 4.8.0M4 for ffmpeg development (Ubuntu)

  28 janvier 2018, par boergi

  I am using Eclipse IDE 4.8.0M4 on Ubunto 16.04. I try to compile the code from a FFmpeg tutorial on GitHUB : (https://github.com/leandromoreira/ffmpeg-libav-tutorial/blob/master/0_hello_world.c). For setting up FFmpeg in Eclipse i used this guide :(https://trac.ffmpeg.org/wiki/Setup_Eclipse_IDE_for_FFmpeg_(Linux)).

  The header files and libaries are all in the folder /home/git/ffmpeg. (e.g. avcodec.h and libavcodec.a is in the folder /home/git/ffmpeg/libavcodec). Included libs : -lavcodec -lpostproc -lz -llzma -lrt -lavfilter -lswresample -lavdevice -lswscale -lavutil -lavformat

  Console output :

  I found out that "int avcodec_parameters_to_context(AVCodecContext *codec, const AVCodecParameters *par)" is defined in utils.c (also in the /libavcodec folder), but i don’t know what can i do to get this running.
