  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Error in converting audio file format from ogg to wav [on hold]

    9 juin 2014, par Sumit Bisht

    I am trying to convert an ogg format file that was created using webrtc (html5 usermedia content generated on firefox) and transferred and decoded on the server into a wav file through ffmpeg but am getting this error on cmmand line while trying to convert :

    $ ffmpeg -i 2014-6-5_16-17-54.ogg res1.wav

    Error opening filters!

    Although, I am able to play the file on server and using the same command, am able to convert .ogg files generated somewhere else. What might be I missing ?

    Edit :
    Here’s the source code that is used to write to the file :

    1) During startup - use the methods of getUserMedia API.

    navigator.getUserMedia({
           audio: true,
           video: false
       }, function(stream) {
           audioStream = RecordRTC(stream, {
               bufferSize: 16384
           });
           audioStream.startRecording();

    2) During stopping of the recording - extracting the recorded information.

    function(audioDataURL) {
        var audioFile = {};
        audioFile = {
          contents: audioDataURL
        **strong text**};

    On server end, the following code is creating a file from this data :

    dataURL = dataURL.split(',').pop(); // dataURL is the audioDataURL as defined above
    fileBuffer = new Buffer(dataURL, 'base64');
    fs.writeFileSync(filePath, fileBuffer);
  • How to scale and position watermark to scale ?

    26 avril 2013, par Cobra_Fast

    I'm scaling a video and applying a watermark like so :

    ffmpeg -ss 0:0:0.000 -i video.mp4 -y -an -t 0:0:10.000
    -vf \"[in]scale=400:316[middle]\" -b:v 2000k -r 20
    -vf 'movie=watermark.png,pad=400:316:0:0:0x00000000 [watermark];[middle] [watermark]overlay=0:0[out]'
    out.flv

    However, the applied watermark seems to be scaled to the original video size rather than the smaller scaled video size.

    This command line worked on ffmpeg version 0.8.6.git and now behaves differently after an upgrade to version N-52381-g2288c77.

    How do I get it to work again ?


    Update 2013-04-26 :
    I now have tried to use the overlay filter's X and Y parameters instead of padding without success.
  • ffmpeg "Header Missing" error recoding mp3 files

    26 juin 2012, par Jonathan Coe

    I have an mp3 encoding server running on Ubuntu (natty). This has been working perfectly up until maybe a week or two ago. I believe I ran an update, which seemed to break the encoder for me - every time I try to run the encode script, it fails out with the error "Header Missing". Files that encoded previously without any issues no longer encode.

    I am getting the following output when I run a basic ffmpeg script (that worked fine previously). Any ideas what is going on ?
