• ffmpeg pipe blocks while capturing

  26 juin 2013, par Marco Vasapollo

  I have this code :

  public InputStream getInputStream() throws Exception {
  
      try {
  
          process = Runtime.getRuntime().exec("ffmpeg -f dshow -i video=\"" + query + "\":audio=\"" + microPhoneName + "\" -r 25 -vcodec mpeg4 -acodec mp3 -f avi -");
  
          } 
  
          catch (Exception e) {
  
          }
  
      return process.getInputStream();
  
  }

  When i use the inputStream.read(b) command, it works only for a little bit of times (180 to 400 times, depending from formats and codecs I use) then the inputStream lock on read and the application doesn't go anymore.

  What's the problem ? Memory saturation (ffmpeg process memory is at least 14mb) ?
  Is there a way to unlock this situation (clean memory, use a file as a bridge to prevent locks) ?

  Of course I need a little bit of "realtime", and not "post-process".
  I'm not constrained to use ffmpeg, I can change it if necessary.

• ffmpeg throws conversion error, but only if the triggering web request is made from safari ?

  22 novembre 2022, par Kyoshiro Kokujou Obscuritas

  I'm using ffmpeg to do an on-the-fly conversion of audio files to ensure high compatibility. i'm converting them to OGG. and all of this is done by a .NET 6 REST service.
This service is then accessed by a javascript Frontend.
Now the problem. The exact same request runs through without any problems on Windows + Firefox, but it does not on Safari. In Safari it says something about "unknownConversion failed"

  


  it's the same file, it's the same name, and to make sure there are no weird invisible characters i used the Microsoft File API to convert it to a proper file path.

  


  code looks like this

  


  var ffmpeg = new Process();
        var startInfo = new ProcessStartInfo("D:\\Programme\\ffmpeg\\bin\\ffmpeg.exe",
            $"-i \"{path.FullName}\" -c:a libopus -f ogg -")
        {
            RedirectStandardError = true,
            RedirectStandardOutput = true,
            RedirectStandardInput = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };
        ffmpeg.EnableRaisingEvents = true;
        ffmpeg.StartInfo = startInfo;
        ffmpeg.ErrorDataReceived += OnErrorDataReceived;
        ffmpeg.Exited += OnFinished;

        ffmpeg.Start();
        ffmpeg.BeginErrorReadLine();

        return File(new BufferedStream(ffmpeg.StandardOutput.BaseStream), "audio/ogg");

• Nuxeo video conversion issue

  14 septembre 2016, par pradeep gowda

  I am new to nuxeo. Let me describe.

  Description :
  1. Nuxeo requires external service ffmpeg to convert video in to different formats[mp4,webm etc...]
  2. ffmpeg is installed
  3. Problem in Video conversion

  If i start nuxeo as below

  Path= $NUXEO_HOME/bin
  ./nuxeoctl start

  No issues, Works fine.

  But i am facing issue in video conversion when i start nuxeo as daemon service.

  service nuxeo start

  Below is my Bash Script :

  #!/bin/sh
