错误: avcodec_init()；

Question

我将尝试在Ubuntu14.04.2下编译，并得到以下错误：

VideoPlayerPipHd.c: In static member function ‘static void reel::VideoPlayerPipHd::Create()’:
VideoPlayerPipHd.c:792:6: error: ‘avcodec_init’ was not declared in this scope
      avcodec_init -> avcodec_register_all;
      ^
VideoPlayerPipHd.c:793:7: error: ‘av_open_input_file’ was not declared in this scope
   av_open_input_file -> avformat_open_input;
   ^

守则是：

787     void VideoPlayerPipHd::Create()
788     {
789         if (!instance_)
790         {
791             instance_ = new VideoPlayerPipHd;
792             avcodec_init();
793             avcodec_register_all();
794         }
795     }

我试过几件事，但我被困住了。有人能帮帮我吗？提前感谢

答案是，ffmpeg函数被废弃了。参见这里的列表，例如：https://www.ffmpeg.org/doxygen/0.8/deprecated.html

例如，将av_open_input_file更改为avformat_open_input。
