How do I go live on YouTube?
To go live on YouTube with OBS, enable live streaming on your channel, create or schedule a stream in YouTube Live Control Room, copy the stream URL and key into your encoder, then start streaming. The first activation can take up to 24 hours, so do that step before the event day.
Enable YouTube Live before you need it
Open YouTube Studio, verify that your channel is eligible for live streaming, and request live access if it is not already enabled. YouTube may take up to 24 hours to enable the first live stream on a channel; after that, new streams can usually go live right away.
Once live streaming is enabled, use Live Control Room to create an immediate stream or schedule one for later. Scheduling gives you a shareable watch page ahead of time and lets viewers set reminders.
- Verify the channel and resolve any live-streaming restrictions first.
- Create a stream in YouTube Studio or schedule the event in Live Control Room.
- Keep the stream key private; regenerate it if it is ever exposed.
Stream key, RTMP and RTMPS
The stream key identifies your YouTube stream. The server URL tells your encoder where to send video. Standard RTMP works, but RTMPS is the encrypted version and is the better default when your encoder supports it.
In Live Control Room, YouTube may show an RTMP URL first. Use the lock option to reveal the RTMPS URL, then copy that URL and the stream key into OBS or your hardware encoder.
Set up OBS for YouTube
In OBS, open Settings > Stream. Choose YouTube - RTMPS if the preset is available, or choose Custom and paste the RTMPS server URL plus your stream key. In Settings > Output, set a bitrate your upload can sustain with headroom, then send a short private or unlisted test before the real broadcast.
For latency, Normal is the safest quality-first option, Low is a good balance for chat interaction, and Ultra low is best only when real-time conversation matters and your connection is very stable. Lower latency leaves less buffering room, so it can make network issues more visible to viewers.
Common YouTube go-live gotchas
If YouTube says it is not receiving data, check that the RTMPS URL and key match the exact stream you created. If the preview appears but viewers cannot see it, confirm the stream is public or that you have clicked Go live in Live Control Room when using a managed event.
Dropped frames usually mean the upload path cannot keep up with the bitrate. Lower the bitrate, use wired Ethernet instead of Wi-Fi, and avoid sending separate full streams to multiple platforms from the same PC.
Frequently asked questions
How long does it take to enable YouTube live streaming?
For a channel enabling live streaming for the first time, YouTube says activation may take up to 24 hours. Do it at least a day before your first event.
Should I use RTMP or RTMPS for YouTube Live?
Use RTMPS when your encoder supports it. It is RTMP over an encrypted TLS connection, and YouTube provides an RTMPS URL in Live Control Room.
Can I go live on YouTube and other platforms from OBS?
Yes. Send one feed from OBS to a server-side relay such as Stream Repeater, then add YouTube and the other platforms as destinations.
