• using ffmpeg for live streaming MPEG-TS with windows media services

  14 mars 2012, par Yanniv

  I'm trying to live stream MPEG-TS source to Windows Media service.
  I found how to live stream using RTMP with this code :

  ffmpeg -y -f mpegts -i udp://@:1234 -re -vcodec libx264 -maxrate 700k
  
  -r 25 -s 640x360 -deinterlace -acodec libvo_aacenc -ab 64k -ac 1 -ar 44100 -f flv "rtmp://rtmp1.youtube.com/videolive?sparams=<stream parameters="parameters" here="here">"
  
  </stream>

  • How can I convert it to support WM9/VC1 format ?
  • Does ffmpeg support pulling of the stream or only pushing to Windows Media services ?

• download and fill file on fly

  4 mai 2017, par Gianluca Calabria

  I’m trying to create a service for a client which takes some audio chunks and concatenate them. For this I’m using FFmpeg. The user should also be able to download the result on the fly without waiting for the conversion/concatenation to finish. The idea is to "fill" the file as the process goes on. I cannot work my way around it, is it possible to do ? I’m using a RESTful service which calls a class like this one

  public ReadableRepresentation serveDownloadRequest(Representation entity) throws SystemInitializationException {
  
      InputStreamChannel inputStreamChannel;
  
      Form reqParameters=getQuery();
  
      try {
  
  
  
          String parameters = readStringParameter(reqParameters, AudioCutAndJoinParameters.PARAMETERS, AudioCutAndJoinParameters.PARAMETERS_MANDATORY);
  
          trace.debug(this.getClass().getSimpleName() + " parameter " + AudioCutAndJoinParameters.PARAMETERS + "=" + parameters);
  
  
  
          String inputUri = readStringParameter(reqParameters, AudioCutAndJoinParameters.INPUT_URI, AudioCutAndJoinParameters.INPUT_URI_MANDATORY);
  
          trace.debug(this.getClass().getSimpleName() + " parameter " + AudioCutAndJoinParameters.INPUT_URI + "=" + inputUri);
  
  
  
          String markInRelative = readStringParameter(reqParameters, AudioCutAndJoinParameters.MARKIN_ID_RELATIVE, AudioCutAndJoinParameters.MARKIN_ID_RELATIVE_MANDATORY);
  
          trace.debug(this.getClass().getSimpleName() + " parameter " + AudioCutAndJoinParameters.MARKIN_ID_RELATIVE + "=" + markInRelative);
  
  
  
          String parametersString = readStringParameter(reqParameters, AudioCutAndJoinParameters.PARAMETERS_STRING, AudioCutAndJoinParameters.PARAMETERS_STRING_MANDATORY);
  
          trace.debug(this.getClass().getSimpleName() + " parameter " + AudioCutAndJoinParameters.PARAMETERS_STRING + "=" + parametersString);
  
  
  
          String cmdFolder = readStringParameter(reqParameters, AudioCutAndJoinParameters.COMMAND_FOLDER, AudioCutAndJoinParameters.COMMAND_FOLDER_MANDATORY);
  
          trace.debug(this.getClass().getSimpleName() + " parameter " + AudioCutAndJoinParameters.COMMAND_FOLDER + "=" + cmdFolder);
  
  
  
          Map markInIdRelativeMap=JsonEntityManager.getInstance().deserializeMap(markInRelative);
  
          Map parametersMap=JsonEntityManager.getInstance().deserializeMap(parameters);
  
          List <string> InputUri= JsonEntityManager.getInstance().deserializeList(inputUri);
  
  
  
          InputStream transcodeOutput = Services.getInstance().runAudioCutAndJoin(parametersMap,markInIdRelativeMap,InputUri,parametersString,cmdFolder);
  
          inputStreamChannel = new InputStreamChannel(transcodeOutput);
  
  
  
          ReadableRepresentation result = new ReadableRepresentation(inputStreamChannel, MediaType.AUDIO_ALL);
  
  
  
          Disposition disp = new Disposition(Disposition.TYPE_ATTACHMENT);
  
  
  
          disp.setFilename("test-cut.wav");
  
          result.setDisposition(disp);
  
  
  
          return result;
  
  </string>

  I’m using the process.getInputStream() as return of my runAudioCutAndJoin but no download happens until the process of conversion/concatenation is done. Can somebody please help me out ?
