  • 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.

  • Realtime video processing with javacv on Android

    7 août 2014, par moonie

    I wish to do realtime video processing on Android using opencv/javacv. My basic approach can be summarized as follow :

    onCreate(), generating a new JavaCameraView

    mCameraView = new JavaCameraView(this, mCameraIndex);
    
mCameraView.setCvCameraViewListener(this);   
    
setContentView(mCameraView);

    when the user clicks a button, a ffmpegframe recorder is created

    try{
    
            final long currentTimeMillis = System.currentTimeMillis();
    
            final String appName=getString(R.string.app_name);
    
            final String galleryPath=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
    
            final String albumPath=galleryPath+"/"+appName;
    
            final String photoPath=albumPath+"/"+currentTimeMillis+".avi";
    
            FFmpegFrameRecorder recorder=FFmpegFrameRecorder.createDefault(photoPath, 640, 360);
    
            recorder.setFrameRate(30);
    
            recorder.start();
    
            }catch(FrameRecorder.Exception e){
    
            e.printStackTrace();
    
            }

    then for each CameraFrame, use the following code to process and save the frame

        public Mat onCameraFrame(final CvCameraViewFrame inputFrame){
    
    final Mat rgba = inputFrame.rgba();
    
    //...apply some filters on rgba
    
    if(mIsTakingVideo){
    
        try{
    
          recorder.record(MatToIplImage(rgba,640,320));           
    
        }catch(FrameRecorder.Exception {
    
            e.printStackTrace();
    
            }       
    
    }
    
    return rgba;
    
}
    

    
 public IplImage MatToIplImage(Mat m){
    
  Bitmap bmp=Bitmap.createBitmap(m.width(), m.height(), Config.ARGB_8888);
    
  Utils.matToBitmap(m, bmp);
    
  IplImage image=IplImage.create(m.width(),m.height(),IPL_DEPTH_8U,1);
    
  bmp.copyPixelsToBuffer(image.getByteBuffer());
    
  return image;}

    When the user clicks the button again, the recorder is stopped and released. However the video I create is an empty video. Any idea why ?

    EDIT :
    The video was empty because the format avi is not supported on my test phone...
    Now the video is not empty but it has the following errors

    1. The recorded video has two split windows instead of just one window
    2. The color is very different from the object I recorded
    3. The play rate is too fast.

  • Android : How to overlay video and audio by using ffmpeg ?

    23 août 2014, par Chau Sin Ting

    I wanna make a android app which can overlay a audio to a video by clicking a button and I am using ffmpeg. The format of my video and audio are mp4 and mp3. I want the output video format is mp4. I have searched for many solutions but none of them give me a satisfied result. All of them are just replaced the original audio of my video to the audio of the audio file. What I want is to overlay my aduio file to the video file and keep the sound of the video at the same time. Does anyone have any idea to do this ? Thank you !
