• Error -138 returns "Error number -138 occurred"

  29 avril 2016, par bot1131357

  I am trying to create a program that listens for a period of time, and then times out so that it can return to work on other tasks and retry again later. Here is the code I am testing with :

  AVFormatContext *pFormatCtx = NULL;
  
  AVCodecContext *codecCtx = NULL;
  
  AVCodec *codec;
  
  int ret = 0;
  
  
  
  // Register all formats and codecs
  
  av_register_all();
  
  avformat_network_init(); // for network streaming
  
  
  
  AVDictionary *d = NULL;           // "create" an empty dictionary
  
  av_dict_set(&d, "timeout", "5", 0); // add an entry
  
  av_dict_set(&d, "rtsp_flags", "listen", 0); // add an entry
  
  
  
  char filename[100];
  
  sprintf_s(filename, sizeof(filename), "%s", "rtsp://127.0.0.1:8554/demo");
  
  
  
  
  
  //:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  
  printf_s("Open video file.\n");
  
  // Open video file
  
  ret = avformat_open_input(&pFormatCtx, filename, NULL, &d);   // Returns -138 here 
  
  if (ret <0)
  
  {
  
      printf_s("Failed: cannot open input.\n");
  
      av_strerror(ret, errbuf, ERRBUFFLEN);
  
      fprintf(stderr, "avformat_open_input() fail: %s\n", errbuf);
  
      continue;
  
      //return -1; // Couldn't find stream information
  
  }

  In the listening mode, avformat_open_input() returns -138. Using av_strerror() gives the following explanation : "Error number -138 occurred"

  Is this an Easter egg ? What does -138 stand for ?

• If I pass this code in Windows console it works, but when I emulate windows console in node.js code doesn't work, and returns unclear error

  22 décembre 2016, par Maxim Cherevatov

  I have code :

  cmd.get(
  
      'trimp3  ant.mp3 ant2.mp3 00:00 00:20',
  
      function(data){
  
          console.log('the node-cmd cloned dir contains these files :\n\n',data)
  
      }
  
  );

  If pass this code in Windows console it works well !
  But, when i emulate windows console in node.js this code not work, and returns unclear mistake :

  [!!] ERROR:  "ffmpeg" �� ����� ����७��� ��� ���譥�
  
  ��������, �ᯮ��塞�� �ணࠬ��� ��� �������� 䠩���.

  To emulate the use node-cmd.

• android ffmpeg halfninja av_open_input_file returns -2 (no such file or directory)

  20 janvier 2012, par cdavidyoung

  I have built ffmpeg for Android using the code and method described at

  https://github.com/halfninja/android-ffmpeg-x264

  using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at

  FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

  but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file :" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.
