  • Automated installation script of MediaSPIP

    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.
    The documentation of the use of this installation script is available here.

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.

  • Convert a Video that it can show with preview in telegram via bot api

    7 avril 2016, par siavashg

    I Have a video and i want to send it with telegram bot api by pytelegrambotapi library so i write this code for send video by bot :

    import telebot
    

    
bot = telebot.TeleBot("TOKEN")
    

    
@bot.message_handler(commands=['start'])
    
def send_welcome(message):
    
    video = open('1.mp4', 'rb')
    
    bot.send_video(message.chat.id,video, duration=)
    

    
bot.polling(none_stop=True)

    but I send a video and it has been sent successfully but telegram show black screen for my video like this picture
    Telegram With Black Scrreen preview of video.
    I think this is about the encoding . I found this site for encoding and it said the videos in telegram have specific format.

    Conditions to trim a video

    • Audio codec = mp4a
    • Video codec = supported by the device
    • Any side of the video more than 640px
    • Or if a side is less than 640px but video codec is h264

    Conditions to compress a video

    • Any side of the video over 640px
    • Audio codec = mp4a
    • A video encoder different than :
    • OMX.google.h264.encoder
    • OMX.ST.VFM.H264Enc
    • OMX.Exynos.avc.enc
    • OMX.MARVELL.VIDEO.HW.CODA7542ENCODER
    • OMX.MARVELL.VIDEO.H264ENCODER

    How can I send Video with blur image preview of that in telegram with telegram bot api ?
