Nimble Streamer supports AVC/H.264 and HEVC/H.265 codecs for ingesting into YouTube.

Set up the YouTube live event
In the "Basic info" tab of the Info and Settings page, enter the relevant information about the stream (title, description, date/time, location, and so on) into the fields. For Type, select "Custom (more encoding options)" and press the "Create event" button.
In the "Main Camera" tab of the event's "Ingestion Settings" page, under "Choose maximum sustained bitrate of your encoder", select the ingestion option that best represents your network and encoding capabilities (for our example we choose 300 Kbps - 700 Kbps (240p)). We use low bitrate to guarantee streaming in any mobile network.
Under "Select your encoder", select "Other encoders". Then, copy the "Stream Name" and "Primary Server URL" information to some text document. We'll need this information to configure Nimble Streamer. Press the "Save changes" button.
Now we need to perform media server configuration. Do not close YouTube tab, we will return to it later for live stream checking.
Configure the stream republishing in Nimble Streamer
Go to "Interfaces" tab and press "Add RTSP interface" button.
Specify the port number in appeared dialog, this port number will be used in Larix Broadcaster settings. Select your media server instance and press the "Save" button.
Go to "RTMP republish" and press the "Add" button.
Specify the "Source application" and "Source Stream" parameters in the appeared dialog, they will be used in mobile application settings. In the "Destination address" field provide the value of "Primary Server URL" field from YouTube live event settings. Leave default "Port" value 1935. Type live2 in the "Destination application" field. Specify the value of "Stream Name" field from YouTube setting in the "Destination application" field.
So, the Nimble Streamer configuration is completed. Proceed to configure mobile application.
Install, set up and launch Larix Broadcaster
Read the "Larix Broadcaster mobile streaming setup and usage" article for YouTube streaming setup details.
Then return to YouTube streaming.
Launch the YouTube live event and check the result
When the "Stream Status" is GOOD click the "Start Streaming" button.
Your live streaming should be started on YouTube. To view your live stream click the "View on Watch Page" button.
Now you can verify that live steaming from your mobile device is launched on YouTube.
The quality of live streaming depends of your mobile device computing power and connection speed in your cellular provider network.
Larix Broadcaster is used as example in this article. Any device (DSLR or web-camera) can be used as a source for a live broadcast stream. Such applications as Adobe Flash Media Live Encoder or FFMPEG can be used as an your live video encoder. Nimble Streamer equally well streams and restreams RTMP both to YouTube and to any other CDN from any source of live video.
Troubleshooting
1. If the stream fails to appear at YouTube, try changing pixel format to yuv420p. YouTube requires this for all incoming streams, so make sure you have it.
2. YouTube requires both video and audio in your live stream. It cannot process video-only or audio-only input streams.
Further usage
You can see some other examples of RTMP republishing:
- Re-publishing in Nimble Streamer
- Streaming to Facebook Live
- Streaming to Periscope
- Publishing to Limelight CDN
- Publishing to Akamai CDN
- Publishing to Edgecast CDN
- Re-publishing to Wowza with proper authentication and ModuleSecureURLParams module.
You may also consider re-publishing incoming RTMP streams with inserted ads. Nimble Advertizer provides a framework for inserting pre-roll and mid-roll ads into live streams for further output via RTMP, SLDP and Icecast with custom business logic and per-user ads. So if you create RTMP stream with ads insertion and pull it for further re-publishing, you can provide your target CDN with properly sponsored content.
Visit Advertizer web page to find out more about server-side ads insertion functionality.

If you need to change the outgoing content in any way, like change the bitrate, use our Live Transcoder for Nimble Streamer to transform. It has high performance and low resource usage.
