How to end youtube live stream? Usually when started a live stream through YouTube Studio, the streaming starts but there's no option to stop it. If streaming through another service such as Zoom, ending the meeting does not turnoff stream.
The YouTube Events (legacy) supports this. The following is an answer to already posted question but at the time of writing I just have joined this community hence does not have reputation to answer (kinda sad but at least I got to post it as self-answering Qs for others).
Step # 1: Go to YouTube Studio > Manage
Step # 2: Click on Events on the bottom right
Step # 3: An Event window will open. Click Edit next to your streaming video
Step # 4: Click Live Control Room tab on the next screen
Step # 5: Here you can see the Stop Streaming button
Step # 6: Now back on YouTube Studio, you can see the streaming has been stopped
Note that this is working till 15 April 2020 and since YouTube Events are going away, this might not be available but then it may be shown in YouTube Studio. Right now (15 Apr 20) there's no option in YouTube Studio to turn streaming off. YouTube thinks that streaming may be stopped due to an error at your end and it might get resolved within couple of minutes, however it eventually ends the stream at a later time.
