use of youtube-dl in my own python script

[yasoob]

I am trying to make a youtube downloading website and was going to use youtube-dl in my site. I wanted to know that how can i just get the variables with the results instead of results being printed on the screen.
for example if i run the main.py file with the url i get the printed output but i want that if i import Infoextractors file and then pass it a url it can give me back a variable possibly a list with the result which i can access for further use. Can anyone illustrate this with an example. I would be really grateful to you guys.

Side note: I should have separated the output methods to a different
class instead of including them in the downloader class when I rewrote
the program long ago. That could be a welcome change if the current
maintainers decide to do it, IMHO.

Ouch, I shouldn't have quoted the original message while replying by
mail. I'll repeat my comment below.

You should look at the method extract_info in FileDownloader, it returns a list of info dictionaries for each element founded.

[yasoob]

it is not working. It is throwing exceptions........ like the params does
not have a get method. Perhaps you can explaina bit more with an example?

What are the errors you get?
For example this is what I use:

class NoneFile(object):
    '''
    A file-like object that does nothing
    '''
    def write(self,msg):
        pass
    def flush(self,*args,**kaargs):
        pass
    def isatty(self):
        return False

class ScreenFile(NoneFile):
    def write(self,msg):
        logging.debug(msg)

class SimpleFileDownloader(youtube_dl.FileDownloader):
    def __init__(self,*args,**kargs):
        super(SimpleFileDownloader,self).__init__(*args,**kargs)
        self._screen_file=ScreenFile()
        self._ies = youtube_dl.gen_extractors()
        for ie in self._ies:
            ie.set_downloader(self)

Then I can do:

fd = SimpleFileDownloader({'outtmpl':'%(title)s'})
results = fd.extract_info(url, download = False)

This will get the videos information.

this is the whole input and the error which i get after following your method

Sorry, I forgot to mention that you needed to include the logging module, add import logging at the start of the file. (I use it because I didn't want to get the messages in the screen)

[yasoob]

have put into making this.......you guys rock.......<3

hey sorry for bothering you again . Now the problem is that my script is working great and is producing the download links........you can visit it on yasoobcode.appspot.com but now the problem is that when i click on download button the download page gives me a 403 forbidden header......Is there some problem with my header.......does youtube and other websites require some different header and if so how can i accomplish this that when the user clicks on download button the video starts to download.......Btw i am making this in flask.

I hope to hear from you guys soon. Thanx for your previous help as well

I'm not sure this issues should be discussed here, so if you don't mind you can email me (see my profile).
