README
udemy-dl
A cross-platform python based utility to download courses from udemy for personal offline use.
Warning
Udemy has started to encrypt many of the course videos, so downloading them may be impossible/illegal because it involves decrypting DRM'd videos which opens up the author to DMCA takedowns/lawsuits. If you use udemy-dl and some/all videos are skipped, please don't open a new issue or comment that the issue still exists. All requests to bypass DRM/encryption will be ignored.
If you'd like to see the full context, then read issue 627.
