Description of your question, suggested solution and other information

YouTube added 4K as an option for live streaming. This DASH live stream is not recognized by youtube-dl > only the HLS live streams are displayed; Is it possible to record the 4K live stream?

The sample video is a continuous 4K live stream example.

Recording Youtube 4K videos works flawless, but live streams not yet.

un saludo, beatsmaster
