JSONDecodeError

[Jeyamir]

Today, I was trying to download the following course: https://www.wingfox.com/p/8328/159176 and I'm getting following error:

Don't specify some json file as the cookie. Use the cookie value itself

[Jeyamir]

Hi, I'm not very sure if I'm using the correct cookie values. Please find the attached and kindly verify if I'm using the correct one.
cookies.txt

Initially, the cookie parameter never worked for me. So, what I did was to hard code the "yiihuu_s_c_d" value in main.py. After doing this only I was able to download my other courses that start with 20XXXX without any issue, except for fragment issue in few videos.

But, this course I noticed that it start with 15XXXX and I'm getting errors.

[waz1500]

Your cookie is the value for PHPSESSID or the yiihuu_s_c_d as it's the same value.
Your command is going to be python main.py --id 159131 --cookie 1vgxxxxxxxxxxxxx --subtitles This will download the first lesson on your course called 1. Theory.

Remember the command isn't going to automatically download all videos in a playlist. You'll need to provide and replace the video_id for each video in the playlist.

You shouldn't need to modify main.py or any other files. Make sure you are using Python 3.12 and not any other version.

[DevLARLEY]

You're getting the error because they're responding with an unencrypted manifest, which can be easily implemented. The hard part is that they're also encrypting the MPEGTS header differently than before, which I haven't solved yet.

[Jeyamir]

@DevLARLEY, noted on the unencrypted manifest and encrypting the MPEGTS header differently.
Thank you for the support.

Anyway, I'm getting the following error in python 3.12.

[DevLARLEY]

I've added support for unencrypted manifests in this commit: 314e025
This will "successfully" download the video but the header will still be encrypted
