Earlier in February 2017, YouTube announced that channels with 10,000 subscribers will be able to begin a live stream.
However, they seem to have rolled a silent update as visible on this page which implies that the 10,000-subscriber threshold has been reduced to just 1,000 subscribers.
According to the new update, any channel administrator with 1,000 subscribers can live stream from the iPad, iPhone, and Android app.
The process to ‘go live’ is simple. Install the app and give it permission to access Storage, Mic, and Camera. Verify the channel if prompted. Click on the camera button and go live!
YouTube Channel owners also need to know a few other terms and conditions of using the live stream.
Any violations of its terms of service will lead to restrictions in a live streaming feature. Further, any channel that has been restricted from live streams in the last 90 days will not be eligible for the lower subscriber activation.
Lastly, it is necessary for the YouTube channel to be verified to ensure eligibility.
