I guess OBS? Works on Windows if you use the webbrowser and disable Hardware Acceleration. Be advised though, the resolution and bitrate on browsers alone could be limited and also on linux clients.

I think the best way is still to rely on already ripped content. Though if you want to start creating webrips yourself, afaik people use their cookies and use the streams, that the browsers/applications get pushed and turn them into other video formats. But not at all a pro on this topic. Someone else here is surely better informed than me on this topic.

As everyone else is saying the issue is that priacy is easier.

That said if you have a HDMI recorder and a HDMI splitter (1 in 2 out) you can strip HDCP and record the signal.

With that said there are some fruity USB c tablets which will get you better results. Droid tablets can work too if you are OK with gui

If you don’t want to spend any more:

• VirtualBox

• OBS

VirtualBox to get around DRM (recording software can be seen if video used in host system) and OBS will allow you to record a window.

If mkv is too large then you can use Handbrake to convert it to MP4 or m4v.

Just be sure to have any mics muted during recording and also mute notifications

Probably OBS would be your first try, it should be able to do a video capture and is Linux compatible.

Or if you’re willing to set up a VM running Windows you could look into the non-free closed-source stream rippers for 720p/1080p. e.g. RedFox AnyStream, DVDFab StreamFab, etc.

EDIT: Just realized AnyStream also has Linux builds so that could be a non-free closed-source solution.

I don’t know if they implemented something against screen recording, but I use SimpleScreenRecorder. But even VLC can do screen recording using the “Stream” option.

If you screencap, use Firefox - you may get a blank screen if you attempt to capture Chrome

I needed to capture my desktop a few days ago, Vokodscreen did it simply and worked like a charm

AnyStream?

I haven’t used it, but it is available for Debian/Fedora, despite being proprietary.

And you have to pay for it.
