I have created a new google account, then I have enabled youtube live streaming and started to stream. I have app key and access token for my user, but http get request to https://www.googleapis.com/youtube/v3/liveStreams?part=snippet&access_token=MY_TOKEN&key=MY_KEY&mine=true is returning zero results, meanwhile at the moment I have live stream.
What to do?
Try using LiveStreams.list instead. It returns a list of video streams that match the API request parameters. There's an example for your code reference.
I found the saving clue in this SO answer. To receive the list, one has to explicitly provide the broadcastType parameter to the query.
Acceptable values are:
all – Return all broadcasts.
event – Return only scheduled event broadcasts.
persistent – Return only persistent broadcasts.
If you find this answer useful, please make sure to upvote the linked answer (as well). I just copy-pasted this.

Microsoft recommends to use delta function in combination with Subscriptions/Notifications to synchronize mailbox. So my plan is:
Create subscription
Receive notification about new mail in inbox
Use delta function to get latest changes in the inbox
My mailbox already has several thousands of letters. If I run the query
https://graph.microsoft.com/v1.0/users/{id}/mailFolders/inbox/messages/delta
It will return in response #odata.nextLink with $skiptoken param many times and only after I get all the thousands of emails in my mailbox I will receive response with $deltatoken to track new changes.
Is there a way to get deltatoken after the first request? I don't want to synchronize the old messages. I want to skip all old messages in inbox and have a fresh start.
Today the delta query functionality does not support this scenario. To request new features please post ideas to uservoice
This is supported for some endpoints. You can use $deltaToken=latest to get just a deltaToken without any resource data. It's not, as far as I can tell, available for mailboxes… but who knows, maybe it will be soon.
This is not documented anywhere in the documentation for the specific APIs that do support it, but is instead documented in the Overview for change tracking. Why? Because Microsoft wants you to be sad all the time.
I am trying to fetch metrics like views, likes, dislikes for videos in some popular public Youtube channels and also subscription information of the Channelsa on a daily basis. Also, country wise stats and gender wise stats for the channels required. But, Youtube Reporting API always prompts authentication. Is there any way to fetch those metrics for public Youtube channels without user authentication?(https://www.googleapis.com/youtube/analytics/v1/reports - need to use this API). Your suggestions will be very helpful.
For some of read-only requests you can just use access token without need to authorize. Check the documentation. Each request's documentation tells if authorization is needed.
The API you linked to is part of the "YouTube Analytics and Reporting APIs", which is split up in these very two pieces - analytics and reporting. I don't see why you need to use this exact API, but I can tell you that you won't succeed with it. This API is intended for channel owners and network owners to get information about their own channels. You absolutely have to authenticate via OAuth in order to use it, there is no way around this.
In order to get video and channel metrics, you can consult the YouTube Data API. Here, an API key from the Google Cloud Console will let you fetch any public data without further authentication. But it will not provide you with data records in specific periods of time, it always returns the current values of the requested properties.
In other words: what you are asking is, as far as I know, impossible to achieve with any official YouTube API.
A workaround for your problem would be to fetch the desired properties via the Data API on a, say, daily basis and compare their values to the previous day's values and calculate the delta.
My company runs a live web stream and has started duplicating this to YouTube. Unfortunately the staff won't check if it's live and internet issues cause our web encoder to stop encoding at times.
Is there a programmatic way I can tell if a channel is ACTUALLY streaming? i.e. if live video is coming out the channel and not just that "the channel is live"?
You may use Search: list.
Using this request returns a collection of search results that match the query parameters that you have specified in the API request. Add part=snippet in your request since this is a required parameter. Then, you may add the following optional parameters with their corresponding values in your HTTP request:
channelId=[channelId] - to search resources created by a particular channel.
type=video - to retrieve a particular type of resource
eventType=live - to return only active broadcasts. Please note that if you use eventType, also set the type parameter's value to video.
Combining all of these parameters, you may send HTTP request using the following format:
https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCXswCcAMb5bvEUIDEzXFGYg&type=video&eventType=live
To better filter your search, you may also opt to add more parameters that are listed in supported parameters.
Lastly, solution in this related SO post - How to check if YouTube channel is streaming live might also help.
I want to fetch location of person and connections so how should I specify fields for this purpose?
http://api.linkedin.com/v1/people/~/network/updates:(update-content:(person:(id,headline,location)))?type=CONN
If I'll make another calls for just getting location, it will be very costly for me, as it will require to make extra calls for each of new connection and will increase number of calls exponentially. So, I want some solution using which I can get location in network updates API call itself.
EDIT: And another thing I need is to check about the privacy setting of connections. As per my knowledge, linkedin doesn't provide any api which returns that which connection allows to see updates and which are not. So, when I try to get network update for a particular connection, it returns error that this user doesn't allow public to see updates. If I want to check this thing before call network updates API, how can I do it in Ruby Language.
OR
Let me know some way to pass multiple dynamic IDs while calling linkedin API.
When retrieving person data associated with a Network Update, it appears that only the basic fields are available. The solution would be to get the id for the person and make a second call to the Profile API:
http://api.linkedin.com/v1/people/id=12345:(first-name,last-name,connections,location)
Currently, linkedin doesn't provide any API for this purpose. You have to make multiple calls for this purpose. But you should make these calls in chunks to avoid timeout issues.
Reference
Try this api
`String url = "https://api.linkedin.com/v1/people/~/connections:(id,first-name,last-name,location,picture-url,positions:(title,company:(name)))"; `
How do I play a track from a SoundCloud URL, which, for example, I got from the xml response from a query
<stream-url>https://api.soundcloud.com/tracks/31164607/stream</stream-url>
I should have thought that it would have been as easy as:
https://api.soundcloud.com/tracks/31164607/stream&client_id=my_client_id
yet I get
<error>401 - Unauthorized</error>
All I want to do is consume it in a Silverlight MediaElement, so all I need is set some url to the MediaElement's Source property.
I've checked an application that I wrote about 2 years ago, and THEN, accessing the stream url was as easy as this for a public track:
http://api.soundcloud.com/tracks/18163056/stream&consumer_key=MY_CONSUMER_KEY
however this no longer seems to work.
For example, all I had to do then in C# was:
MediaElement me = new MediaElement();
me.Source= new Url("http://api.soundcloud.com/tracks/18163056/stream&consumer_key=MY_CONSUMER_KEY");
me.Play();
Any hints would be appreciated.
I had a reply on a Microsoft forum that seems to imply that SoundCloud might not be possible to stream to Windows 8 Metro devices without consuming the whole stream before playback starts - which is quite worrying and would seem to imply that to make authentication possible, it would have to be done entirely in the url querystring insterad of using the header:
(The following reply is the answer to the following question: 'I am able to access an audio stream by http using the MediaElement, however I need to access it via https in which I need to add the oAuth info to the header of the initial request.
How is this done when using a MediaElement, and if it cannot be done, what is the workaround for consuming an audio feed in Metro 8 that requires header authentication to stream?')
"Direct access to the underlying network stream is not currently permitted by the MediaElement. Because of this there is currently no way to modify the header of the HTTP request to include any additional authentication information. That said, you do have control over the URL. You could theoretically setup an HTTP proxy service that translated the HTTP GET request parameters into the necessary oAuth credentials. Keep in mind that this is just a theoretical workaround. You may find different behavior in practice. Another theoretical workaround would be to handle the oAuth yourself via a raw stream socket and pass the retuned media data to the MediaElement via "Set Source" and a "Random Access Stream". Please keep in mind that this method has major limitations. in order to use a "Random Access Stream" with the ME you need to make sure all of the data is available before passing it to the ME."
The proxy service is not scalable for an application that is merely distributed for free as every stream would need to come via the proxy. And the raw stream socket, although getting around this, would mean that playback could not start until the whole file had downloaded - and this goes against all current UX (User Experience) guidelines.
So once again, if anyone has any tips, or info about how the whole authentication thing can be achieved in a querystring instead of using headers, I'd appreciate it!
I'm a little confused about whether you're referring to a public or a private track? If it's a public track, then you shouldn't need to send any authentication information, just your client id.
When I request https://api.soundcloud.com/tracks/31164607/stream?client_id=YOUR_CLIENT_ID then I get a 302 redirect to the proper mp3 stream.
Remember, adding parameters to a URL must start with a ? not &. This could (more than likely) be the reason why you are getting a 401 (SC is not picking up the client_id).
After authentication the link like this
http://api.soundcloud.com/tracks/103229681/stream?consumer_key=d61f17a08f86bfb1dea28539908bc9bf
is working fine. I am using Action Script.
I'm following up on Tom's reply because he calls attention to url character specificity. My HTTP requests randomly started failing today, and I was prefacing my client_Id with a ?. As soon as I changed that single ? to &, it started working. So in my case, SC wasn't picking up my client_Id because I used the wrong character. I think depending on where in the request we're talking about specifically, it's worth noting that differences between ? and & do make a difference.
