Hi, im trying to get the example from https://www.ffmpeg.org/doxygen/trunk/decode_video_8c-example.html running.
Im using Qt Creator (C++) with Widgets and compiled ffmpeg manually (Kubuntu 18.04.0 64 bit). Unfortunately im getting "undefined reference" errors for every avcodec function (e.g. avcodec_send_packet https://www.ffmpeg.org/doxygen/trunk/group__lavc__decoding.html#ga58bc4bf1e0ac59e27362597e467efff3 (dec_ctx, pkt) ...) I added headers and libs in the qmake file with: INCLUDEPATH += /home/user/ffmpeg_build/include LIBS += /home/user/ffmpeg_build/lib/libavcodec.a I have tried: extern "C" { #include <libavcodec/avcodec.h> } without success. I attached a file with the "undefined reference" errors. Kind Regards
undefined_ref_log
