For the past couple of weeks (?) Jaksta has been downloading some of the videos I watch - I don't think it's all of them, and I think my own uploads are frequent culprits.
Heaven knows how to block them - here is an example of one of their links, they're all similar but DIFFERENT!
I wonder if you can help, it's very disruptive to have the download "horn" sounding out when I'm concentrating (which is difficult for me at the best of times!)
If you dont like the beep when downloads finish then switch off Settings > Personalization > Enable sound effects
That link is a youtube video.
Switch off AUTO if you dont want to detect things or if you need to leave it on because it is recording (as apposed to downloading) then click the green thumb icon that appears when AUTO is on. This will switch of processing of new streams.
Alternatively if you never want to detect youtube streams, then you can block googlevideo.com in the Settings > Internet Downloads > Advanced > AdBlocker.
Im not sure how a video could be captured unless you were watching it or loaded the page it was on.
You could try also adding youtube.com to the adblocker and see if that stops it.
You only need to put the domain name in googlevideo.com, not the entire url.
Please provide debug logs showing a video bypassing the adblocker.
