  • 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 ?
