@tinker Try downloading the video with yt-dlp first. If that fails, the simplest option is probably a HDMI splitter and a HDMI capture card (HDMI splitter will take care of HDCP DRM, since HDMI capture cards won't process HDCP-protected video).

Point "video" camera at screen in a dark room.
Optionally connect an audio cable, but you need a stereo attenuator from line/earphone level to microphone level for that.
Some phones are good enough.
A S/H Canon DSLR or "mirrorless" Panasonic digital photo camera can record hours of HD on and SD card, better than most camcorders. Only the professional movie 4K cameras are better than the newer "mirrorless" Panasonic sold as still cameras, for 4K!

Do not share or upload the video!

@tinker I use a forked and extended version of https://github.com/yt-dlp/yt-dlp. I have a slightly different use case. My kids get told to watch videos for school, but often they are not viewable on kid accounts. Ironic I know. But I have an agent that scans the kid's StudentVue for video links and downloads them to our Plex.

My other is for my partners that like to watch videos during adult time. They can send video links to a telegram bot that will download the videos for us.

@tinker yeah, audio routing gets you there. OBS Studio with a PipeWire or PulseAudio monitor source captures it, with screen. Analog FTW. A 2003 attempt to block it (Analog Reconversion Discussion Group) failed and Cory says he was the guy who defeated it. That said, he presses his EFF thumb down on the history: https://www.flyingpenguin.com/doctorows-disinvention-of-the-vcrs-history/

@tinker If all else fails, you can get an HDMI video+sound capture device. On UK ebay, they're less than £10. I got one to enable video recording of laptops whilst I was installing Linux on them - works well, you just have to set the external video port to mirror the screen, but I suppose if your player uses DRM, it might be blocked.

@tinker my favourite janky method is to do screen record without audio, then take a long aux cable and just wire it from your audio out to your audio in, record it through Audacity or anything like that and then put them together in openshot

@tinker that's how you end up recording your actual monitor with your phone, trying to make no noise.

Reminds me of the 80s, with a mic and stereo recorder to capture some tv show's theme song :)

In Firefox you can just save videos via right click which could be simpler and do the trick. Just right-click any video and Save Video is an option.

If for some reason that doesn't work, and depending on how the videos are served, yt-dlp is likely able to do the trick.

I have had success recording sound from a browser using qpwgraph connnecting the browser output to audacity input. It's supposed to be able to redirect video as well, but I haven't tried that. I'd suggest kdenlive for sound and audio to record as it should be able to take both inputs. It's a little complicated because it's a rally full featured video editor but it's not too bad to get the basics down and ignore the more complicatwd studf.

@tinker I have both OBS and USB capture but for this specific issue I found a great script for Tampermonkey. Did an entire week course recording in an hour whereas the others require you streaming each video.

@tinker my first idea would be to use OBS as a screen recorder :)

@tinker try OBS. I've been using that to record meetings and webinars which I couldn't attend in real time.

@tinker Easiest solution is going to be buying a USB video capture device and looping audio+video out the HDMI port and back into the capture device.

@tinker

Would not "simplerecorder" fit ?
