How to get video stream from sites?

Question

HTML

Hello. There are sites, for example: www.ontvtime.ru, https://yandex.ru/efir?from=morda&stream_channel=1... , how to get a video stream from them (for personal use)?

Answer 1

We open the web development panel on the page, go to the Network tab, and click on the play button on the video and see the loaded stream url in the network tab, but how it is formed, where it comes from is always different)
In the case of onv stream for ptr2 comes from 185.40.28.4/stream/FFA0945BCCDF6716182022242628304... (at the end of the characters is a timestamp)
But again, if you open the page in a browser, it will not give you anything, most likely there is protection on the server side for returning by referral, by server or by ip etc.
