[Libav-user] linker error while compiling decoding_encoding.c

[satya gowtham kudupudi]

I compiled finally after couple of days!

If its CPP application you should

extern "C" {
#include <libavutil/opt.h>
#include <libavcodec/avcodec.h>
#include <libavutil/channel_layout.h>
#include <libavutil/common.h>
#include <libavutil/imgutils.h>
#include <libavutil/mathematics.h>
#include <libavutil/samplefmt.h>
}

and my build commands are

g++ -D__STDC_CONSTANT_MACROS   -c -g -Iffmpeg_build/include
-D__STDC_CONSTANT_MACROS -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o
build/Debug/GNU-Linux-x86/main.o main.cpp
g++ -D__STDC_CONSTANT_MACROS    -o dist/Debug/GNU-Linux-x86/test
build/Debug/GNU-Linux-x86/main.o -Lffmpeg_build/lib
-L/usr/lib/i386-linux-gnu ffmpeg_build/lib/libavformat.a
ffmpeg_build/lib/libavcodec.a ffmpeg_build/lib/libswscale.a
ffmpeg_build/lib/libavdevice.a ffmpeg_build/lib/libavfilter.a
ffmpeg_build/lib/libfdk-aac.a ffmpeg_build/lib/libpostproc.a
ffmpeg_build/lib/libswresample.a ffmpeg_build/lib/libx264.a
ffmpeg_build/lib/libavutil.a -lvpx -lvorbisenc -lvorbis -lmp3lame -lopus
-ltheora -ltheoraenc -ltheoradec -lva -ldl -lzip -lz -lpthread

we need to link heck amount of libraries
