@shirishag75 Can you post some more example URLs, especially one's from different institutions, if you have any? This is so I can get an idea of how the URLs are formatted.

shirishag75 commented 4 years ago

while there could be many and I lost the ones which I wanted to but still here are few to start by. I am just giving links to the webpages and not to the videos themselves , although it's just a matter of just lifting the URL's, investigating them though is not my cup of tea .

https://yale.hosted.panopto.com/Panopto/Pages/Home.aspx

I guess you can see how things are going to be.

Any updates on this - I have a bunch of classes from MIT I'd love to cache up on my computer before I lose access.

jxu commented 3 years ago

You can use the method here https://github.com/jstrieb/panopto-download or my quick and dirty script https://github.com/jstrieb/panopto-download/issues/3

Klaaktu commented 2 years ago

Not sure if it's specific to each institution, but the download button and RSS feed only give the lowest quality option. Though downloading the highest quality using youtube-dl seems easy enough:

  1. Find highest quality index.m3u8 in F12. There is also a master.m3u8 showing all the options.
  2. Give the address of the index.m3u8 to youtube-dl.

Edit: yes the podcast/download quality is a setting for the video owner.

jxu commented 2 years ago

For my institution I think there is only one quality stream which is sufficient quality

jxu commented 2 years ago

btw this has been implemented downstream in yt-dlp

ZanderBrown commented 2 years ago

Why not submit it here?

jxu commented 2 years ago

idk how extractors work and if the PR is compatible with downstream

jxu commented 2 years ago

If you are able to get the master URL, I have a tool that can download it. For example, here is the master URL for the video in the original post:

So it is a index.m3u8 downloader? That already exists in youtube-dl and yt-dlp

jxu commented 2 years ago

Yes, see above https://github.com/ytdl-org/youtube-dl/issues/22688#issuecomment-913946462
