  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • WebRTC : unsync audio after processing using ffmpeg (audio length is less than that of video)

    22 novembre 2013, par QuickSilver

    I am recording a video and using RecordRTC : WebRTC . After receiving the webm video and wav audio at server, I'm encoding it to a mp4 file using ffmpeg(executing shell command via php). But after encoding process, the audio is unsync with video (audio ends before video). How can I fix this ?

    I have noticed that the recorded audio is 1 sec less in length with video.

    js code is here

    record.onclick = function() {
    
    record.disabled = true;
    
    var video_constraints = {
    
        mandatory: {
    
            "minWidth": "320",
    
            "minHeight": "240",
    
            "minFrameRate": "24",
    
            "maxWidth": "320",
    
            "maxHeight": "240",
    
            "maxFrameRate": "24"
    
        },
    
        optional: []
    
    };
    
    navigator.getUserMedia({
    
        audio: true,
    
        video: video_constraints
    
    }, function(stream) {
    
        preview.src = window.URL.createObjectURL(stream);
    
        preview.play();
    

    
        // var legalBufferValues = [256, 512, 1024, 2048, 4096, 8192, 16384];
    
        // sample-rates in at least the range 22050 to 96000.
    
        recordAudio = RecordRTC(stream, {
    
            /* extra important, we need to set a big buffer when capturing audio and video at the same time*/
    
            bufferSize: 16384
    
            //sampleRate: 45000
    
        });
    

    
        recordVideo = RecordRTC(stream, {
    
            type: 'video'
    
        });
    

    
        recordVideo.startRecording();
    
        recordAudio.startRecording();
    

    
        stop.disabled = false;
    
        recording_flag = true;
    
        $("#divcounter").show();
    
        $("#second-step-title").text('Record your video');
    
        initCountdown();
    
        uploadStatus.video = false;
    
        uploadStatus.audio = false;
    
    });
    
};

    ffmpeg command used is :

    ffmpeg -y -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4

    Currently I'm adding an offset of -1 to ffmpeg, but i don't think it's right.

    ffmpeg -y -itsoffset -1 -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4
