YouTube Live Streaming API Limits - youtube

I need to create an application that will automatically publish multiple video streams on different youtube channels of my clients.
can I publish applications from one stream to different channels or one application - one channel?
can I concurrently publish several independent live events per channel? what are the restrictions on the number of concurrent events?
By default, for the YouTube Data API v3 i have 3,000.0 units/second/user Per-User Limit. What this means? Do I understand correctly, that every client will be able to see the live broadcast, that i created through this api is not more than 3'000 seconds?

Rate limit for YouTube Live Streaming API (Live Chat Messages)

I am writing a chat bot for my channel. It has six webcams and adding more soon. The bot will enable viewers to move the cameras around and take snapshots by entering commands into the live chat. However, for this to work well, I need to query the API every few seconds. I'm concerned that I will run into rate limits. I found a page with a calculator but it doesn't have any of the live chat API calls listed. Is there a rate limit to call the YouTube Live Streaming API (Live Chat Messages)?
thank you in advance

Going live in Youtube by using embedded player in the application is a violation?

I am building an app which does live streaming to Youtube channel using an embedded player. So i want to know if it violates the policy of Youtube since I am using a different application to do live to the youtube Also, all the application users will stream to a single youtube channel, so any idea in how many live streams can take place at a time?
It was stated in the Broadcast and Stream documentation of the YouTube API that "only one event is live at any given time, and the video content for each broadcast is unique". To learn more about policy, you can read the YouTube API developer policies.

Is it possible to use the YouTube Live Stream API to broadcast through my phone camera?

I want to create a basic app that allow users to simply start to broadcast a video through their phone camera (front and back) just by pressing a button.
Does the YouTube live stream API allow me to handle the video streaming process?
If so, is YouTube Live Stream API totally free of charges and will never ask me to pay something if I reach a certain amount of usage?
Creating a Live Event and Live broadcast is language and hardware agnostic, just use YouTube's Live Streaming HTTP API. Read through the Core Concepts and Life of a Broadcast guides.
Your flow might look something like this:
Authenticate the user.
Set up and schedule your Live Broadcast object.
Start your video encoder and create a Live Stream Object.
Bind your Live Stream to your Live Broadcast.
Test to verify your video is going through.
Set your Live Broadcast to Live.
At the conclusion of your event, set your Live Broadcast to Ended.
Note that setting up your encoder is on you. Asking "How do I create an RTMP or DASH video encoder for [hardware or software]" is too broad of a question for Stack Overflow.
The YouTube API is free to use within a specific quota. If you hit that quota limit, there are ways to request additional quota from Google (potentially for a fee).

Does the YouTube Data API expose multi-camera livestream functionality?

I am trying to integrate a YouTube live event which uses multi-camera views as per Google's documentation into a site - I'd love to be able to access both camera views from the live event if possible.
Does the YouTube Data API support querying the multiple different camera views? Are they listed as children of a single event? What's the returned data structure like?
Or is this simply not possible - i.e. a single live event with multiple cameras will show in the API as just a standard live event?
The YouTube Live Streaming API does not support multiple camera angles at this time. The API docs specify that a liveEvent can only be bound to one liveStream
liveStream - Contains information about the video stream that you are transmitting to YouTube. The stream provides the content that will be broadcast to YouTube users. Once created, a liveStream resource can be bound to exactly one liveBroadcast resource. (Similarly, the liveBroadcast resource can only be bound to one liveStream resource.

Brightscript: how to pull my Youtube videos from my own channel onto the Roku?

I'm making a youtube channel for some meteorologists who hired me for an internship.
They want to use Youtube to pull their videos and display them onto the Roku Channel. How would I do this? also, I need to make a list of the videos from the youtube channel. one more thing if anyone knows how to pull information from a website that would be wonderful.
We have to figure out how to pull information for weather services and we have a few websites that use XML and RSS data tables, but theres so many different Weather stations that it would be a frustration to write so many If statements to contain those stations. is there a way to find their local weather station? If only one of these questions can be answered, I would prefer it be how to pull videos from youtube and play them on your channel.
While there are ways to pull YouTube videos for playback on Roku, it is disallowed by the YouTube Terms of Service. If you want to stream videos, you'll need to host them on your own CDN.
Per the YouTube TOS, Section 4.C.:
You agree not to access Content through any technology or means other than the video playback pages of the Service itself, the Embeddable Player, or other explicitly authorized means YouTube may designate.
As for weather services, you'll need to provide more information on what you're trying to do. Most weather services (e.g., Weather Channel, Weather Underground, AccuWeather, etc.) have APIs that can identify the user's location based on IP address, but these services typically cost money, especially if you intend to use them in a commercial application.
