  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • FFMpeg runnig example for creating video from images

    21 octobre 2014, par user2361084

    I have google a lot but not found any running example for creating video from images.
    I found that Ffmpeg can be used for creating video but because of lack of knowledge of jni I could not understand how I can use Ffmpeg lib. Please suggest me how I can create video from Images. How I can use Ffmpeg for the same or any other running example. Thanks in advance.

  • I cannot convert a set of images taken from a FTP to a video using FFMPEG

    7 septembre 2022, par Victoriano Fernández Tomás

    I am writting a python code where I am trying to convert a set of images that I take from a FTP into a video using FFMPEG but I cannot. I have tried, instead of reading the folder where the images are, to read a txt file with the name of the images that I want to use, with the format needed in order that FFMPEG could read it propertly, but I get always the same error : Protocol 'ftp' not on whitelist 'tcp'
In the same code, I also try to change the format of one video and change the resolution and size, and this part of code works well.
However, writting as input the same reference of the FTP, the images' code fail and the video's code works.
Besides, I have tried in my terminal as local the same command I write in the code for the images, and in local it works propertly, but not in the code.
Here there is a part of my code :

    


    Video's code (it works) :

    


    command = """ffmpeg -i {i} -an -crf {r} {o}""".format(i=src_path,o=path,r=resolution)


    


    An example of this command when I run this is the next (I dont want to write the exact ip and port) :

    


    ffmpeg -i ftp://user:user@ip:port/landing_ffmpeg/pruebas/pruebahd.mp4 -an -crf 45 tmp/pruebasalida456.mp4


    


    And next the images' code (it doesnt work) :

    


    command = """ffmpeg -loop 1 -framerate {ips} -i {i} -t 10 -pix_fmt yuv420p {o}""".format(i=src_path,o=path,ips=img_per_sec)


    


    An example of this command is the next :

    


    ffmpeg -loop 1 -framerate 2 -i ftp://user:user@ip:port/landing_ffmpeg/pruebas/prueba_imagenes/prueba06.jpg -t 10 -pix_fmt yuv420p tmp/videoimagen.mp4


    


    And the error I get with this code is the next :

    


    [ftp @ 0x560eb3e11800] Protocol 'ftp' not on whitelist 'tcp'!
[image2 @ 0x560eb3e09380] Could not open file : ftp://user:user@ip:port/landing_ffmpeg/pruebas/prueba_imagenes/prueba06.jpg


    


    I dont get this error when I try to run the command of the video, only for the images. And both commands run propertly when I write in my terminal in local, with local paths.

    


    I would appreciate if someone can help me to solve the problem and fix my code.

    


    Thanks !
