Description

WRITE DESCRIPTION HERE
Youtube.dl does not have support for mixclouds new streaming service. The livestream is located at https://www.mixcloud.com/live/ followed by the persons username. You will need to remove beta from the url in the repo as mixcloud is no longer in beta with this feature as it is now live on server.

Can confirm same issue, for example https://www.mixcloud.com/live/electroradiofm/ is live right now (but may not be when you read this message). When I try to run youtube-dl on the URL I get this:

When I use chrome dev tools, I find some m3u8 files being retrieved, I tried passing them into youtube-dl (this has worked on other sites that aren't supported) it did not work, get these errors:

Also one other point of data, plus a tip for anyone else waiting on youtube-dl updates, this chrome extension is able to save mixcloud live streams when run in "Capture Mode" https://chrome.google.com/webstore/detail/stream-recorder-download/iogidnfllpdhagebkblkgbfijkbkjdmm?hl=en (the documentation's not the greatest so not sure how helpful this is)
