  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • Video playback in Python not working

    6 juin 2016, par user3354383

    I am having trouble getting video playback to work for Python. I am using Spyder as my IDE.

    I am trying to play a video file from my computer using the code below but I can not get any video to play, it won’t even open a new window for playback.

    I have looked at some threads about this problem but none of the following solutions seem to work :

    1. changing the ffmpeg file name to opencv_ffmpeg_(version number)_64(if it is a 64 bit)
    2. moving the ffmpeg file to the python27 folder
    3. moving the ffmpeg file to the dll folder

    My code :

        import numpy as np
    
    import cv2
    

    
    filename = 'C:/Users/ishraq/Downloads/traffic2.mp4'
    
    vidcap = cv2.VideoCapture(filename)
    

    
    while(vidcap.isOpened()):
    
    success, frame_org = vidcap.read()
    

    
    cv2.imshow('frame',frame_org)  
    

    
    if cv2.waitKey(1) & 0xFF == ord('q'):
    
    break
    

    

    
    vidcap.release()
    
    cv2.destroyAllWindows()

  • when muxing , ffmpeg just support stereo only ?

    23 août 2016, par C.sandy

    environment : ffmpeg 3.1.1, xcode 7.3.1, ios 9.3

    My purpose is to mux H.264 and AAC stream(real time) to an mp4 file. Everything seems just right while recording(ffmpeg does not report an error or warning), and the result file can be played very normally on VLC. However, the file has no sound when playing on my cellphone or QuickTime on the computer, which pictures can be shown just right. I’ve done some analysis, and the result is :

    1.video both input and output is normal and right ;

    2.input audio has params channel:mono & sample_rate:8000HZ, while output audio has channel:stereo & sample_rate:16000HZ(VLC told me the parameters of the output file). I didn’t do any converting about the audio.

    So, my question is : when muxing into mp4 file, does ffmpeg only support stereo ? If not, how could I prevent this converting and make the audio played normally on cellphone and QuickTime ?
