FFmpeg Ubuntu链接器错误

Question

我正在尝试使用来自Ubuntu 12.04的ffmpeg lib和c ++来解码音频。 我在这里关注代码https://0xdeafc0de.wordpress.com/2013/12/19/ffmpeg-audio-playback-sample/

下面是用于编译代码的命令

g++ -std=c++11 decode_play_audio.cpp -I/home/codeDev/ffmpeg_sources/build_Mar-10-2016/include -L/home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib  -lavcodec -lavformat -lavutil

但是如下所示得到编译错误，

我已经构建了最新的ffmpeg 3.0并位于/home/codeDev/ffmpeg_sources/build_Mar-10-2016/

我可以看到位于/home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib

  libavcodec.a
  libavfilter.a
  libavutil.a
  libswresample.a
  pkgconfig
  libavdevice.a
  libavformat.a
  libpostproc.a
  libswscale.a

错误：

Answer 1

我通过添加更多链接器选项解决了这个问题，例如-lavformat -lavcodec -lswscale -lavutil -lavfilter -lswresample -lavdevice -lpostproc -lao -lz -lx264 -llzma -lbz2 -lva -lrt

Answer 2

看来你缺少一些链接库，我的测试代码：

//testFFmpeg.c
#include <stdio.h>
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>

int main(int argc, char *argv[])
{
    printf("hello ffmpeg\n");
    AVFormatContext *pFormatCtx = avformat_alloc_context();

    if (avformat_open_input(&pFormatCtx, argv[1], NULL, NULL)) {
        fprintf(stderr, "open input failed\n");
        return -1;
    }

    if (avformat_find_stream_info(pFormatCtx, NULL) < 0) {
        fprintf(stderr, "find stream info failed\n");
        return -1;
    }

    int videoStream = av_find_best_stream(pFormatCtx, AVMEDIA_TYPE_VIDEO, -1, -1, NULL, 0);

    printf("nb:%d, url:%s, time:%ld, duration:%ld, bitRate:%ld, videoStream:%d\n", 
            pFormatCtx->nb_streams, pFormatCtx->url, pFormatCtx->start_time, pFormatCtx->duration, 
            pFormatCtx->bit_rate, videoStream);
    return 0;
}

我的编译命令：

gcc testFFmpeg.c -lavformat -lavcodec -lavutil -lswresample -lz -llzma -lpthread -lm -I/usr/local/include -L/usr/local/lib
