Looks like this does not find anything:

re.findall

Could you test by using a print statement instead of _durationstring = to print the following? :

re.findall(r'Duration: ([0-9:]*)', matches[0])

[agermanidis]

The main issue seems to be that it's dealing with an image as a video, that's why it tries to get the duration of the video w/ ffprobe and fails. It's strange, as I tried creating a Snap from a png file and it correctly handled it on my machine, but I'll look into it further.

@krissrex I cannot reproduce the error, but now, it outputs this error ( it sends the image as a video. )

have you tried using guess_type() on your image? And could you post the code for you bot

[N07070]

I did not try to use the guess_type(). Here is the code of the bot :

#!/usr/bin/python
# -*- coding: utf-8 -*-
from argparse import ArgumentParser
from snapchat_bots import SnapchatBot, Snap
from snapchat_bots.utils import save_snap

class FbStoryBot(SnapchatBot):

    # Acceuillir l'utilisateur
    def on_friend_add(self, friend):
        self.log(str(friend)+" has added me !")
        self.send_snap(friend, Snap.from_file('resources/auto_welcome.png'))

    # Dire au revoir si il nous supprime
    def on_friend_delete(self, friend):
        self.log(str(friend)+" does not want me anymore...")
        self.send_snap(friend, Snap.from_file('resources/adieu.png'))
        self.log("Said goodbye.")
        self.delete_friend(friend)

    # Ajout d'une story
    def on_snap(self, sender, snap):
        # Ajout d'un log dans un fichier texte ?
        self.log("Recived a snap from "+str(sender))
        save_snap(snap)
        self.post_story(snap)
        self.log("Saved the snap in the directory.")

if __name__ == '__main__':
    # parser = ArgumentParser('Auto-Welcomer Bot')

    # parser.add_argument('-u', '--username', required=True, type=str, help="Username of the account to run the bot on")
    # parser.add_argument('-p', '--password', required=True, type=str, help="Password of the account to run the bot on")

    # args = parser.parse_args()

    bot = FbStoryBot('xxx', 'xxx')
    #Lister tout les utilisateurs puis le nombre d'utilisateurs.
    print("I have "+str(len(bot.get_friends()))+" friends !")
    bot.listen()

[EthanBlackburn]

I found it.

if media_type is MEDIA_TYPE_VIDEO or MEDIA_TYPE_VIDEO_WITHOUT_AUDIO

should be

if media_type is MEDIA_TYPE_VIDEO or media_type is MEDIA_TYPE_VIDEO_WITHOUT_AUDIO

[agermanidis]

I corrected this earlier:

https://github.com/agermanidis/SnapchatBot/commit/e21e52c66d32c6aa032acbd546307ab80a1794e1

[N07070]

So how do I implement it ?

[agermanidis]

Have you tried running your code on the last commit? You shouldn't need to use guess_type, your issue might've been already fixed with https://github.com/agermanidis/SnapchatBot/commit/e21e52c66d32c6aa032acbd546307ab80a1794e1

[N07070]

Okay, it's fixed ! :smile:
