  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • Python OpenCV real-time blurring with saving to output

    10 janvier 2024, par Oleg Novosad

    I have a live video stream via RTSP from my IP camera. I want to blur faces on that stream and output for mobile usage (HLS, H.264, etc). All this should ideally happen in real-time — with the minimum of resources consumed. I plan to deploy this later to some cloud, so the less money I spend on resources the better.

    


    Currently I have a working solution like so :

    


      

    • I capture video using OpenCV

      • 


    • I update every frame with Gaussian Blur and save it to some folder

      • 


    • After some amount of frames I create MP4 / AVI / whatever video and make it accessible via HTTP URL

      • 


    • All of it is running on Django for now

      • 


    


    I know I am doing something wrong, can someone suggest a better solution ?

    


  • dnn : add layer pad which is equivalent to tf.pad

    29 juillet 2019, par Guo, Yejun
    dnn : add layer pad which is equivalent to tf.pad

    the reason to add this layer first is that vf_sr uses it in its
    
tensorflow model, and the next plan is to update the python script
    
to convert tf.pad into native model.

  • DivX audio not decoded on DVD player

    8 août 2019, par Shaul

    Moved to https://video.stackexchange.com/questions/28225/divx-audio-not-decoded-on-dvd-player

    I am converting MP4 movie into AVI/DivX format. I plan to copy the AVI to a USB memory stick and plug it into my DVD player. My player is a Pioneer 3052 that supports USB input.

    I convert the file using ffmpeg without error messages. The output file is played correctly on my computer, including audio. I use "Movies & TVs" and "DIVX Player" for testing.

    When I try running it on my Pioneer the video and the subtitles are ok but there’s no audio. I know that there’s no issues with the hardware because videos converted with "FreeMake Video converter" do play audio.

    My command line is :

    .\ffmpeg.exe  "-i INFILE -c:v mpeg4 -vtag xvid -qscale:v 3 -c:a libmp3lame  -vf "scale=720:576:force_original_aspect_ratio=decrease,pad=720:576:(ow-iw)/2:(oh-ih)/2","subtitles=f=SRTFILE:charenc=ISO-8859-8:force_style=PrimaryColour=&amp;H0000FFFF,Fontsize=16" OUTFILE

    I also experimented with -b:a 192k, -b:a 96k and -qscale:a 4 all leading to the same results.

    I wander what else to try.
    I add the report produced by ffprobe (for the output file) :
