Question

I have tried everything in the book and EVERYTHING I could find on how to do this and reinstalled and reconfigured and rebuilt several times to no avail. This is what I have. I’ve made FFMPEG on my Ubuntu VM and have the following code written:

#include "libavcodec/avcodec.h"
#include "libavformat/avformat.h"

#include <stdio.h>
#include <iostream>

using namespace std;

int main( int argc, char* argv[] ) {

    avcodec_register_all();

    return 0;
}

This errors and says:

/home/adam/workspace/MP4 Tools/Debug/../testDriver.cpp:19: undefined reference to     `avcodec_register_all()'
collect2: ld returned 1 exit status

I have included the libavcodec.a file. Project->Properties->GCC C++ Linker->Libraries->add “avcodec”

Can anyone think of something I’m not doing or overlooking? Thanks so much.

I posted a solution here

but don’t forget that if you use c++ you should include ffmpeg headers in this way:

extern "C"{
#include<libavformat/avformat.h>
#include<libavcodec/avcodec.h>
}
