  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Configuration spécifique d’Apache

    4 février 2011, par

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • How to read a MP3 audio file into a numpy array / save a numpy array to MP3 ?

    15 juin 2021, par Basj

    Is there a way to read/write a MP3 audio file into/from a numpy array with a similar API to scipy.io.wavfile.read and scipy.io.wavfile.write :

    



    sr, x = wavfile.read('test.wav')
wavfile.write('test2.wav', sr, x)


    



     ?

    



    Note : pydub's AudioSegment object doesn't give direct access to a numpy array.

    



    PS : I have already read Importing sound files into Python as NumPy arrays (alternatives to audiolab), tried all the answers, including those which requires to Popen ffmpeg and read the content from stdout pipe, etc. I have also read Trying to convert an mp3 file to a Numpy Array, and ffmpeg just hangs, etc., and tried the main answers, but there was no simple solution. After spending hours on this, I'm posting it here with "Answer your own question – share your knowledge, Q&A-style". I have also read How to create a numpy array from a pydub AudioSegment ? but this does not easily cover the multi channel case, etc.

    


  • ffmpeg (libav, libavfilter, etx) - modify frame with image or text using C\C++ API

    7 juillet 2023, par Alex

    After reading a huge bunch of docs and tutorials I still cant find a way to add some image or text to each frame of video. Something like logo on the frame corner, or text watermark.

    


    Iam know how to do such things with ffmpeg from cli, but for this case, C\C++ code is required.

    


    Looks like, ffmpeg's libav allow me to do some things with frame on decode stage, using AVFrame structure of current frame and add some modifications to it with libavfilter. But how exactly this can be done ?

    


  • Capture video on iOS device and live stream it to a server (or another mobile)

    13 février 2015, par theDuncs

    I want to be able to record footage using my iOS device and stream it directly to a server.

    There’s quite a few articles on S.O. that talk about this, but I’m not sure any have answered the question very well.

    Should I be using HTTP Live Streaming, or is this just for sending data to an iPhone ?
    Should I be using AVCaptureSession to grab the video (a segment at a time ?), sending each segment to the server ?
    Should I be using AVCaptureVideoDataOutput and ffmpeg for streaming ?

    I’m a little lost with all this, so any sample code or docs or links would be really appreciated.

    Thanks for your help guys.
