Cannot get udemy-dl to connect to website to begin downloading course. Says I need user/pass/link but all 3 are typed correct. Can anyone help me figure out what is wrong and how to fix it?

[Errno 2] No such file or directory when downloading course

I'm getting the following error message when I try to download a course:

i have this configuration file:
{
"username" : "[my account]",
"password" : "[my password]",
"resolution" : "1080",
"output" : ""
}

script execution:
python3 ./udemy-dl.py -l https://www.udemy.com/mastering-ansible/learn/v4/

problem with pip install

when I type:

pip install -r requirements.txt

I got this message:

Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

and I have already install all the requirements.
What's wrong with that?

Support for Udemy for Business

Any plans to include support for Udemy for Business accounts? Each business has it's own unique URL i.e. https://mybusiness.udemy.com and the login page URLs are slightly different. I'm not a developer but I've tried to modify the code myself with a find & replace but obviously there's more to it than that. I've included the error I got when trying below with the latest version of code (username and password are in the configuration file not in the command):

MacOSX: Not able to use relative path symbol (~)

Hi there,

It seems that in MacOSX (Sierra), if I specify the output location (using -o option). When I use tilde to indicate my home directory (for example instead of /Users/me/download, I just specify as ~/download), it will just create that as a directory as tilde (~).

Regards,
Zul

about subtitle

1 Could it just add the download subtitle(don't download video) ？ Ex : udemy-dl -subonly
2 Could it change the subtitle format (ex: vtt to srt) ? Ex:udemy-dl -subformat vtt2srt

Tks for your help. This is great.

Thanks!

No Issues, just yours is the first fork I have found that just works (since the requested quality not found issue).

I don't use this to pirate but just to watch my purchased videos at work behind a corporate firewall so this works well for me.

Files with "?" or special chars in Windows (Bash)

udemy-dl can't save or load files with "?" or special characters in their video names

max() arg is an empty sequence

Hello,

I have an issue with this command :
python udemy-dl.py -u [email protected] -p myPa$$w0rdisKewl https://www.udemy.com/learn-microsoft-excel-formulas-and-functions-with-examples/

(coupon code = BLOG_FREE)

The script downloads the first 2 videos then crash with the following output :

[*] : Lecture : '002 Course-Resources-Formulas.zip' (already downloaded). Traceback (most recent call last): File "udemy-dl.py", line 475, in <module> main() File "udemy-dl.py", line 406, in main udemy.ExtractAndDownload() File "udemy-dl.py", line 295, in ExtractAndDownload _url = max(urls, key=urls.get) ValueError: max() arg is an empty sequence

Any idea ?
Thanks in advance

EDIT

It seems like it's because chapter 3 is empty (no video and no file), then videos_dict[chap].items() contains this :

I think the code could be improved to handle that.

Problem about download Resources

Hi, there is 2 problem about resources and links.

first is that you can download only 1x resource link links-to-visit from every chapter. I mean if there is 5x chapter, and every chapter has 8 lecture I can see only the last lecture link. so I cant download lecture 1 - 7 links or resources. and it is possible that every lecture has more than 2-3x resource link

second problem is about Quizzes. this part is not work too

also it is good to add them in another folder. I find an working example here. both problems that I explain above are working here.
https://github.com/madmax2/udemy-dl-windows

but my knowledge is low in python. I will try to add it in future but it is hard for me :)

Subtitle file & some files not downloading

So the script works perfectly fine but for some later lectures it doesn't download the subtitle files. It shows an error that's like "URL ERROR: HTTP Error 403: Forbidden"

I guess it isn't your fault as it downloaded the earlier subs but do you have any idea how can I fix this problem?

Also, I noticed how the script would skip some files from the course. It downloads videos, subs, PDF, zipped & txt files perfectly fine. But it skips over some files. You can see the files it skips here - http://prntscr.com/hefx3z

[PROPOSAL] Add flag to automatically download default quality if requested is not available.

If a non-default resolution is selected via -r any course segments that do not have that quality available require a manual 'y' entry to continue the process. Propose that an additional command line flag be added to automatically download the default if requested is not available.

Cannot Run on MacOSX Sierra using Python 2.7

Hi there,

I've cloned your repo, then I did pip install -r requirements.txt.
But, when actually calling why do I get this:

Traceback (most recent call last): File "udemy-dl.py", line 7, in <module> import udemy File "/Users/310176470/Workspace/udemy-dl/udemy/__init__.py", line 6, in <module> from ._downloader import Downloader File "/Users/310176470/Workspace/udemy-dl/udemy/_downloader.py", line 8, in <module> from .colorized import * File "/Users/310176470/Workspace/udemy-dl/udemy/colorized/__init__.py", line 1, in <module> from .Output import * File "/Users/310176470/Workspace/udemy-dl/udemy/colorized/Output.py", line 1, in <module> from colorama import init,Fore,Back,Style ImportError: No module named colorama

Download captions as well?

[PROPOSAL] Move user/pass to config file instead of command line argument.

Would be nice to be able to place the user and pass in a formatted (JSON|YAML|Plain Text) file that would be pulled in on script run, instead of having to enter them as command line arguments.

Extra Option - Idea

a small idea, it will be good to add an option for download things. a Boolean option like bellow

{
	"username" 		            : "", 
	"password" 		            : "", 
	"resolution" 		            : "",
	"output"                            : "",
        "download videos"                   : "true", // default true . means download videos
        "download caption"                  : "true", // default true . means download captions
        "download quizzes"                  : "true", // default true . means download quizzes
        "download resources"                : "true" // default true . means download resources like links
}

in this case we can save a lot of time and space, and download the parts that is necessary for us

Spanish Characters Support

Hi first thanks for this magnificent script it would be nice to add support for Spanish characters like "á, é, í, ó, ú, ñ".

A good example is "https://www.udemy.com/universidad-java-especialista-en-java-desde-cero-a-master/" the files are coming for example"019 Lecci n_ Variables en Java" instead of "Lección Variables en Java", same problem with the folder structure, comes "03 Fundamentos Java_ Instalaci n de JDK de Java y Herramientas" instead of "Fundamentos Java Instalación de JDK de Java y Herramientas".
Another change that would be great is replacing the character:"_" for "-" (with an space for example "03 Fundamentos Java_ Instalaci n de JDK de Java y Herramientas" to "Fundamentos Java - Instalación de JDK de Java y Herramientas") when ":" is present in titles and video/attachments descriptions.
Thanks in advance, regards!

What is default resolution?

Hi @r0oth3x49,

First thanks for the 'udemy-dl' app. I have a wonder, if we don't pass the "-r" arg as "720", what is your app default behaviour? Will the app list the exist resolution and select max or select first? I wonder it because I ran with "-l" videos don't order by resolution.

Thanks.

Issue with chapters ending in '?'

Hi r0oth3x49, congratulations for this work and thank you from Spain.
I have some downloading problem with a particular Udemy course. In this course there is a chapter named: "¿Puedo ponerme en contacto con los profesores?"
The error is the following:

[*] : Lecture : (006  Puedo ponerme en contacto con los profesores?)
Traceback (most recent call last):
  File "udemy-dl.py", line 893, in <module>
    main()
  File "udemy-dl.py", line 823, in main
    udemy.ExtractAndDownload(path=outto, quality=res, default=True)
  File "udemy-dl.py", line 423, in ExtractAndDownload
    with open(filename, 'wb') as f:
OSError: [Errno 22] Invalid argument: '006  Puedo ponerme en contacto con los profesores?.html'

I think the problem is with the '?' at the end. Because windows don't support this character for a file.

pdf / quizzes

as the topic pdf / quizzes are not detected with this program, so we can download non of these files

Download doesn't work for udemy business

I've tried to use your tool with udemy for business, but the download doesn't work. This is caused by the hardcoded udemy url in your source code. Also if you want to use udemy business, you've adjust the login scrf regex pattern.

Overall the changes to get your tool working with udemy business is pretty simple.
I would offer myself to develop this feature. Are you interested in this?

Parse restricted characters before saving to file

Hi,

When I download video 043 App - Is It Prime? in Swift 4 Deep Dive from the course Complete IOS11 Development Course, the script crashed. On Window, the following characters \ / : * ? " < > | cannot be used in filename so I guess the character ? in the video name is the cause.

I wonder if we could parse those characters into ASCII strings (or something else) before saving to disk?

Thanks

Error downloading Files

Hi, this is an error that I get after around 15-20 min of running program

Resource Bug

Hi, thanks for the new version it work well and caption futures too, just there is one error that I post it in another issue,

ok lets say current issue about this topic
https://github.com/r0oth3x49/udemy-dl/issues/17
about this problem, it is again same but now it is a little changed, there is no .txt file like before. but the same problem about lectures is still bug
lets say we have 3 chapter and 4lecture in chapter 1

chapter 1:
        lecture a:
             download file 1;
             download file 2;
             download file 3;
       lecture b:
       lecture c:
       lecture d:
chapter 2:
     .....................
chapter 3:
     ......................

with starting the program it will download only and just download file 3, and download 2 and download 1 are skipped.

video quality

Hi, I can not download the videos.
What do I do wrong?
I do not understand how the argument for video quality should be written.
I have verified that the videos are at 720.

What if the domain is different as in my case. i.e instead of www the url is wipro .
