YouTube Rolls Out New Live Streaming Platform to All...

by Bern Rexer

YouTube Rolls Out New Live Streaming Platform to all who are currently enabled to stream live.

**** See update below****

Live Streaming Specialist from the YouTube support blog announced yesterday "We are working on improving the YouTube Live experience and are now excited to roll it out to all accounts that are currently enabled for YouTube Live!"

If you are currently enabled to stream live, like many revenue producing YouTube Partners and non-profits are, you will see the following opt-in message from your Video Manager Live Events section.



As I mentioned some specifics in a previous post - there are considerable benefits of using the new platform. Especially with how YouTube utilizes transcoding. Instead of streaming up to four separate bit rates to the media servers - YouTube now allows a single ingest stream of one higher bitrate, up to 6Mbps - 1080p, which it will then transcodes to lower bitrates including to mobile devices. Overall this saves you upload bandwidth and encoding CPU.



Some other neat functions of the new platform are the use of viewer selected cameras called multi-camera events. Think of watching a live stream of a concert and clicking on the camera behind the drummer. Or maybe watching a presentation and clicking the camera with slides only. I can think of lots of uses for this.


The user selected camera is placed above the player:


The live stream can be 'recorded' on the server and the archive is available very rapidly after the live event concludes. Ideally you maintain the same live event URL for your archive with the comments and viewer count intact.

You can even implement a DVR function in case a viewer arrives late - they can scrub backwards in time to see what they have missed.

YouTube has a lot of ground to cover to catch up with mature live streaming services such as Livestream or Ustream but it's apparent they are making tracks. Some of that ground includes enabling live streaming to more partners - which they say will continue to be offered.

Check out YouTube's Live Streaming Guide for the details.

<<<<<<<<<<<<<<<<<<UPDATE>>>>>>>>>>>>>>>>>>>>>

On May 15th, 2013 Google announced 'YouTube live streaming expanding to more channels'. Any channel with over 1000 subscriptions would be eligible to apply for the Live Events feature of streaming video live on YouTube. 
The YouTube Live Support group verified the announcement with further instruction of how to apply for live streaming on YouTube

This announcement is historic in the live streaming industry. Any channel with over 1000 subscriptions is probably in the top 10% of all YouTube channels. However those content producers probably distribute to over 80% of viewers. So this announcement effectively opens up live streaming to most content distributors.  This is the announcement that everyone following YouTube live streaming has been waiting for. It opens up the accessibility of a free content delivery network and will shift many over to YouTube live streaming platform - especially for those that already use YouTube for video on demand hosting.
But it also creates an application mechanism - which had not existed before except to non-profits. This gives YouTube the knowledge of who wants to stream live. 
It may also create more on-demand content and more channels. There will be many whose focus is on live streaming content and not necessarily video on demand. Those live producers have never considered YouTube until now. This gives them motivation to create a channel and gain subscribers to become eligible for live streaming. 
However, we are still waiting - if you are eligible, and after you apply it still takes time to actually become enabled - "Once you’ve applied, access to live will be granted gradually.''

YouTube Changes Live Encoder Settings


<<< UPDATE >>> here are the latest YouTube Live Encoder settings.

YouTube has made notable changes to their recommended live encoding settings. Particularly with the video bitrate increase for each of the four stream resolutions of 240p, 360p, 480p, and 720p - but also adding a 1080p live streaming resolution. These resolutions can be selected by the viewer from the quality cog adjustment on the bottom right of the YouTube player. 


YouTube's addition of a New Platform suggests encoding a single 6Mbps stream which their media servers then transcode to the lower bitrate streams. 

The bitrates have increased considerably as shown from charts below of the old and new suggestions. 
240p increases from 300Kbps to 500Kbps 
360p increases from 600Kbps to 1000Kbps
480p increases from 1000Kbps to 2000Kbps
720p increases from 2400Kbps to 4000Kbps

Most YouTube accounts do not have the ability to stream live. Those that are enabled may only have a basic feature of the streaming to a single bitrate of 360p. And some have the enhanced live streaming feature to stream to all four bitrates. Furthermore, YouTube has added a 'New Platform' for live streaming which transcodes a single higher bitrate stream to the lower bitrates.

Transcoding a single highest bit rate stream down to the lower bit rates and to mobile devices is a big step forward for YouTube live streaming.  A video on the ytliveops YouTube channel discusses transcoding and the new platform.

<<<<<<<<<<<<<<<<<<<<<<UPDATE>>>>>>>>>>>>>>>>>>>>>>>>>>>
YouTube now has updated their encoding suggestions to included a recommended bitrate. This is great news as it shows their is flexibility with encoding bitrate. More testing will determine how the YouTube transcoders  handle dynamic bitrates which is offered by many encoders.

YouTube Live Streaming Guide


The YouTube Live Streaming Guide offers insights and instructions for streaming live on YouTube. If you are an enabled partner or just curious about how YouTube live streaming works then browse through this information.
The guide along with this video were updated early 2013.


June 08, 2012




Live streaming on YouTube will change the way we present our media. Think about the power of Google behind media distribution. I think it will disrupt the streaming media CDN marketplace (and much more).

Remember when YouTube offered video uploads and distribution for free? Many thought that business idea wasn't sound. YouTube probably lost a lot of money initially. But now we see they are the second largest search engine of content (behind Google).

It has been a year since YouTube began offering live streaming (see youtube-is-going-live) and they are limiting who has access to the live feature - but rolling it out incrementally.

Live content on YouTube enables exposure to users who otherwise may not have been able to receive that content. This week the International Olympic Committee and YouTube announced that the London 2012 Olympic Games will be streamed live from the IOC YouTube Channel to users in Asia and Sub-Saharan Africa.

MXPI is enabled to stream live on YouTube and produces or consults for television and live event producers. I've been webcasting for over ten years along with more than a decade of live television experience and true passion for the technology.

So this Blog is about streaming live on YouTube, the technology required, and methods of process along with opinions and best case scenarios.

Hopefully this blog will answer some questions and generate some discussion -
How does the YouTube Live feature work?
Can your YouTube channel benefit from streaming live?
What equipment or services do I need to stream live on YouTube?

Cheers
