Large exercise videos downloads fail

[FascinationSt]

When downloading a course with an exercise file over 2 GB, the download fails and the program generates error, "A fatal error occurred while downloading the course. Check the logs for more info". The course is downloaded, and a file is downloaded, but not the complete exercise file. For example, the course: https://www.linkedin.com/learning/premiere-pro-cc-2019-essential-training-the-basics-2/welcome-3?autoAdvance=true&autoSkip=false&autoplay=true&resume=true&u=107515114

Got the same error after the first ~2GB of the file were downloaded:

Don't download exercise files from the program, download them from the linkedin learning page.

[pcpepik]

@Jowi767 that is the current workaround but this does not fix the issue with the downloader

[ahmedayman4a]

Unfortunately, this is the downside of the downloader class I currently use. Fixing would mean using a different package and rewiting alot of the downloader code.

[Lewis8379]

Same here, also experiencing errors once the download reaches 2GB

The solution to me to get around what developer @ahmedayman4a said, is to behave differently. If I'm downloading 20 courses, and one with files larger than 2GB is the 2nd course, then the download fails and all other 18 courses need to be re-extracted.

Some sort of error that allows me to skip without halting the rest of the operation would certainly be helpful? Same applies to all other errors, the ability to skip would be a solution that is hopefully doable without different packages?

[ahmedayman4a]

I am adding this to the new update that I am working on

[Lewis8379]

Sounds great, I've also had errors for courses that are just bugged out. It might download the first and second folder, create the third, but not download anything to it, even though the course may have five folders worth of content. The logs aren't too helpful for me to understand as a noob, but I'd be happy if I could just skip the course (providing the dialog tells me what course has the problem) and not waste the extraction of the other stuff.

Let me send some Kofi's your way. That will help show my love.

Wow my thanks, I really appreciate it. As for your bugs, make a new issue and upload your log file
