  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • How to capture and store a video in h.264 format using web browsers without Flash ?

    7 novembre 2016, par 2vision2

    How to capture a video and store it in h.264 format using web browsers without flash ?

    As per my analysis, HTML5 can be used to access the camera and microphone without any additional plug-ins as in this link. "http://www.html5rocks.com/en/tutorials/getusermedia/intro/"

    However, i don’t know the possibility of storing the video in h.264 format.

    I would prefer not to install any additional plugins. However if its not possible without any additional plugins, i would accept it. I can also use **Java Applets if needed.

    Is HTML 5 the only option or it possible with JScript itself ? I also hope that ffmpeg can help me too.

  • Play audio from ffmpegframegrabber

    5 juillet 2013, par Shataya

    For an augmented reality app which should play videos, adjusted to the detected marker.
    I can't use the android video view as it is not possible to rotate it.
    Therefor I have imported the javacv and ffmpeg libraries.
    So far I can successfully render my video with opengl es but I have problems with the audio playback.

    I extract the frames with FFmpegFrameGrabber :

    grabber = new MyFFmpegFrameGrabber(Environment.getExternalStorageDirectory()+"/arvideo_"+fileName+".mp4");
    
Frame frame = grabber.grabFrame();
    
....
    
if(frame.samples != null) {     
    
   // I have my audio samples and then?     
    
}

    I tried to playback the audio with the AudioTrack class.

    int bufferSize = AudioTrack.getMinBufferSize(grabber.getSampleRate(),AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
    
track = new AudioTrack(AudioManager.STREAM_MUSIC, grabber.getSampleRate(), AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, bufferSize, AudioTrack.MODE_STREAM);
    
track.play();
    

    
// call track.write(....) ???

    I get only a static noise. I have read that the sample format is AV_SAMPLE_FMT_FLTP but android needs AV_SAMPLE_FMT_S16. That's why I tried to convert the samples with com.googlecode.javacv.cpp.swresample class. I think that I'm doing something wrong because I still have only noise.

    swrcontext = com.googlecode.javacv.cpp.swresample.swr_alloc();
    
com.googlecode.javacv.cpp.swresample.swr_alloc_set_opts(swrcontext,AV_CH_LAYOUT_STEREO, avutil.AV_SAMPLE_FMT_FLTP, getSampleRate(), AV_CH_LAYOUT_STEREO, avutil.AV_SAMPLE_FMT_S16, getSampleRate(), 0, null);
    
com.googlecode.javacv.cpp.swresample.swr_init(swrcontext);
    
// ....
    
PointerPointer inData =  samples_frame.data();
    
PointerPointer outData = samples_frame.data();            
    
com.googlecode.javacv.cpp.swresample.swr_convert(swrcontext, outData, samples_frame.nb_samples(), inData,  samples_frame.nb_samples());
    
samples_frame = new AVFrame(outData);

    I really have no idea anymore... I hope anybody can help me. Thanks.
