    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.

  • Android Camera Capture using FFmpeg

    8 mars 2013, par Stryker33

    Am tryin' to take the preview frame generated by the android camera and pass the data[] to ffmpeg input pipe to generate a flv video.
    The command that I used was :

    ffmpeg -f image2pipe -i pipe: -f flv -vcodec libx264 out.flv

    I've also tried to force the input format to yuv4mpegpipe and rawvideo but with no success...
    The default format of the preview frame generated by android-camera is NV21.
    The way am invokin' ffmpeg is through the Process API and writing the preview frames data[] to the process' stdin...
    The onPreviewFrame() definition is as follows :

    public void onPreviewFrame(byte[] data, Camera camera)
    
{   
    
    try
    
    {
    
        processIn.write(data);
    
    }
    
    catch(Exception e)
    
    {
    
        Log.e(TAG, FUNCTION + " : " + e.getMessage());
    
    }               
    
    camera.addCallbackBuffer(new byte[bufferSize]);
    
}

    processIn is connected to the ffmpeg process stdin and buffersize is computed based on the documentation provided for addCallbackBuffer().
    Is there something that am doin' wrong...?

    Thanks...
