Description

ON24 is used for online trainings like from the O'Reilly learning platform. Replays are available after the training but it seems they cannot be downloaded. I'd like to ask for a download functionality.

@chbndrhnns you need to find stream.mpd file using chrome developer tool.
then use the command
youtube-dl -f bestvideo+bestaudio https://dashod.akamaized.net/media/cv/events/XYZ/stream.mpd
you need ffmpeg for merging formats.
see this stackoverflow link
I've used this method and it works on on24 platform.

@VioletLightning thanks for sharing! If it's possible like that, I would not even need a native implementation.

I think that the main issue there is that they are separating video with audio with actually slides.
Of course, they are providing pdfs, but it would be cool to have a video, audio with actual slides at a particular moment at the time

@chbndrhnns You don't absolutely need it, but then again we don't /need/ most of the extractors either. They just make downloads of common media easier. Please change the label of this request to "site-support-request"

I would also like to plus +1 this request. As an example for why this would be useful: on24 is the streaming media platform behind many Microsoft learning materials.

@remitamine Examples can be found with this google search: site:event.on24.com. Many require a registration. Here is one that is available without registration:

Thank you, @remitamine. Here is another example of a recent Microsoft online learning event URL:

https://ve.on24.com/vshow/MSFTWindowsVirtual/exhibits/WVDMC?regPageId=18844

If I remember correctly, registration for this event is/was required, but is/was open and basic.

I'm interested. How can I help with this effort?

The StackOverflow comment just after the one that @chbndrhnns mentioned also works perfectly for O'Reilly Live Events hosted on ON24. https://stackoverflow.com/a/55071769/5559588

Hello everyone.

Since this issue is still opening, I would like to ask whether it is possible to download the presentation slider video?

No doubt the yt-dlp extractor can be back-ported.
