How to use

• Have ffmpeg installed on your pc and have it in your PATH.
• Download the latest release and extract it.
• Add your username/email and password in config.json.
• Make suitable changes to the config as per your needs. Read here for more information on configuration.
• Execute the binary.

Selecting lectures

When prompted to enter a range do the following

• Enter the numbers shown on the left (not the lecture number after "LEC")
• If you want lectures from 1 to 10, this is how your input will be 1 10. The range is inclusive.
• If you want only 1 lecture say 5, your input should be 5 5.
• Make sure you add space between the start and end.

}

FAQ/Troubleshooting

How do I run this?

Refer to the How to use section.

IT IS NOT WORKING!!!!

• Make sure you have the latest version.
• Make sure you have the correct username and password.
• Make sure you have the correct baseUrl.
• Make sure you have ffmpeg installed and in your PATH.
• Make sure the website is working.

Despite all of them being correct if it is not working, open an issue.

I changed the credentials but it is not giving me data for the new credentials

Delete the .token file. This was a mistake on my part. The program caches the token and does not check for new credentials. This may or may not be fixed in the future.

Does it download both the views?

Yes. It downloaded both the views if they are available and are selected in the config.json.

How do I change to different views in [insert software name]?

You are on your own here. I use mpv and it has a shortcut key mpv-player/mpv#8065 for the same. For VLC the functionality is available from my understanding in some menu. For other software, you will have to look it up.
