I have to make some kind of service, where people can record a video/an audio from the browser and watch/listen it later.
Is there any way to capture audio/video from the browser and instantly upload it to Microsoft Azure cloud service, that would be work on mobile devices too?
I've found how to upload existing video with C# or Java, but I need to stream it to Azure or in an extreme case somehow save it to the my server and upload it with C#/Java to Azure.
I would be grateful for any idea!

To clarify: I have a website hosted in Azure. I want to add a 1.5 minute howto video. I can't imagine it will get shown more than a few tens or hundreds a month (maybe a few thousand if the site takes off).
I was planning on using Azure Media Player to play the video.
In relation to this I thought the video would sit in a streaming endpoint.
But this seems an expensive way of doing this. Are there better ways (especially cheaper)?
EDIT: is it possible to host the video elsewhere and have it embedded in Azure?
The cheap way to do this would be to place the video in a blob storage then play it using a web page.
There is a video explaining how to do this here: https://www.youtube.com/watch?v=qmzns7PgP0A
I would recommended to use Media Service: video-on-demand, content delivery service with an Azure Media Services application in the Azure portal.
Azure Media Services lets you deliver any media, on virtually any device, to anywhere in the world using the cloud. The collection of services provide encoding, live or on-demand streaming, content protection and indexing for video and audio content.
The Windows Azure Media Services platform has four types of services: content uploading, encoding, encrypting content and streaming.
Media Service Pricing: https://azure.microsoft.com/en-in/pricing/details/media-services/
Additional information : Streaming Videos from Azure ( Blob or Media Services)
So, I'm working on an application where admins will be able to upload videos, for others to view on different platforms (mobile devices, computers etc). It is to be hosted on Azure, and I'm having a bit difficulty figuring out if I need to use Media services or simply a CDN.
When does it make sense to use the Media services over simply uploading to a blob and viewing through CDN? What are the advantages of using one over another?
Microsoft Azure CDN pulls content from Azure Media Services streaming server, so you could stream your content from the edge. You don't have to use a CDN if you don't need to deliver content in a large scale at a time. Rather, you could directly streaming content from streaming server offered by Azure Media Services.
The reason you maybe confused is because there are CDN vendors in the market (such as Akamai) offers streaming server capability. But by CDN itself, the edge network was just for caching the bits, not acting like a streaming server.

I am working on a school project and using my MSDN subscription for Azure access. I have written a program that uploads MP4 recordings (video surveillance) from a private network to Azure storage on a scheduled basis.
I want to be able to view these MP4 files using the Azure Media Player. I will be the only one using this stream and it would only be on a very infrequent basis (while away on vacation). I played around with the Azure Media Services a bit and it seemed like the only way I could get an "endpoint" for the media player was to open a live streaming channel. Once I did that it gave me an endpoint which I put in the player and it played my video as expected. I turned in my project proposal to my professor based on this prototype and got it approved as my semester project (40% of my grade).
To my surprise two days later I got an email alert saying that my Azure account had shut down automatically due to my exceeding the $50/mth allocation. I was surprised since the files I uploaded amounted to only 5MB and I only downloaded them twice during my proof of concept work.
While reviewing my billing details it appears all these charges came from the media services channel and it appears to based on the time the channel is "alive". 43 hours of this pretty much ate up my whole allotment for the month.
Here are my questions (keeping in mind I am a decent C# developer but completely green about all things Azure):
1) Am I going about this the right way? Do I need a live streaming channel to use the Azure Media Player?
2) If yes to the above, is there a way I can start/stop the live streaming service from code? In this way could I send a command to Azure to wake up the channel when viewing is needed then shut down when complete?
3) Is there some other html5 based media player I could use against Azure file storage so I bypass the live streaming channel and associated costs?
Thanks for any help. When I called Microsoft support all they could do was explain the billing to me and steered me here for technical support.
Based on your project descriptions you already have files encoded to mp4 and uploaded to Azure Media Services.
You don't need to create streaming endpoint and start live channel to playback your files. You need instruct system to generate playback url which will accesible for you during defined period of time and use this url in player.
Example of code:
IAsset asset =_mediaContext.Assets.Where(c=>c.Name="Your MP4 Asset").First();
IAccessPolicy accessPolicy = _mediaContext.AccessPolicies.Create("Read15Min", TimeSpan.FromMinutes(15), AccessPermissions.Read);
ILocator locator = _mediaContext.Locators.CreateLocator("ReadOnlyLocator", LocatorType.Sas, asset, accessPolicy, startTime: null);
var uribuilder = new UriBuilder(locator.Path);
uribuilder.Path += "/" + asset.AssetFiles.First().Name;
var fileUri = uribuilder.ToString();
To test if it is actually working simply go to http://aka.ms/azuremediaplayer and paste value of fileUri to Url input textbox.
If you serious about security i would recommend to read about Content Protection in Azure Media Services and dynamically encrypt content to use token authentication. In my blog post I showed how you can integrate Azure AD authentication in your ASP.NET MVC app with Azure Media Services to protect your content.
You can point your Azure Media Player directly towards the mp4 file's "Absolute URI" found when marking the file and clicking "Edit" at the bottom.
I´m planning a Azure Web Api and one of the requests is to let users upload Images from their mobile devices to our Blob Storage. The Clients are Windows Phones, iPhones and Android Phones.
Trying to plan the solution, I found a lot of tutorials doing this with Azure Mobile Services. But with scaling requirements, this solution should not be used. Instead we want the Clients to upload Images directly into our Blob Storage, secured by SAS (generated by our Api).
Does anyone knows how to handle the upload of all kinds of actual mobile OS without Mobile Services? Does anyone have some links to tutorials, how-to´s, etc.?
Edit:
I´m not shure, how all different devices handle their photo Uploads?
Posting form data? Mulitpart?
Uploading via REST?
Uploading via FTP?
Because of this question I search for some hints to plan the project forward to accept the simplest solution for all mobile OS.
Any application capable of sending web requests could do the trick, you'll have to be more specific about your needs.
Using the blob REST API ("put" method) as described here is doable from any application. It's only a matter of sending a Http request containing the right headers and the blob as request body. You'll probably have to come up with a way for distributing the shared acces keys if the containers aren't public.
I am in the middle of developing services that will deal with media files (audio/video) . These services are responsible for uploading and then streaming media files uploaded by client (IOS, Android but not limited to these devices/platforms).
We are using node.js with mongodb as database. In the near future our services will be part of Azure. (Portions of our backend are already there in Azure)
In that case i came across Azure media services. I know that it does't have any sdk to work with for Node.js so my only option here is to use REST Service from Azure Media Services.
My question are:
1) Whats the correct approach adapted in this scenario by developers already handling this scenario. I am open for approaches/practices here and change what i am planning to do currently.
2)If i use Azure Media Services. How would my client calls my services (node.js) which acts as a proxy for calling REST Services for Azure Media Services. How will this exactly work and i have file in hand in my proxy to re-upload. Or i will internally direct my services so that internally it uploads to Media Services .
3)How these media files uploaded in media services are related to a record in MongoDB. Like a record can have multiple media files.
I appreciate any pointers/explanations here.
Thanks,
To proper answer your question there are few questions need to be answered.
1.What functionality are you going to provide on top of azure media services. From your question it seems that main goal to let users to upload asset and them to have ability to stream uploaded content.
For this purpose you need to have following steps to be implemented in node js.
Create asset and asset files records in Azure Media Service(WAMS) by calling REST API. http://msdn.microsoft.com/en-us/library/windowsazure/hh973617.aspx
Create access policy and locator which will give URI of blob storage where file needs to be uploaded. WAMS REST API
Upload file using node.js to blob storage http://www.windowsazure.com/en-us/develop/nodejs/how-to-guides/blob-storage/
Create encoding job which will encode you input into multi bitrate mp4. WAMS REST API
Package your multi bitrate mp4 to smooth or HLS format or utilize dinamic packaging feature in WAMs. http://channel9.msdn.com/Series/Windows-Azure-Media-Services-Tutorials/Introduction-to-dynamic-packaging
Once you ready to stream your content you need to give user client playback url pointing to origin server. In order to do this you have to call WAMS REST API and create origin locator
Assets are exposing ID and AlternativeID properties which you can use to map your metadata about content with WAMS assets and implement any additional Content Management logic.
You need to act as proxy if you have some user based authentication and don't want to have dedicate separate azure media account to one user. WAMS provides basic blocks for asset ingest, encode, package, ondemand delivery and in nearest future for live streaming.
It can be used as foundation for your cms system or you can act SSAS provider by adding additional authentication, authorization layer. Currently you can use third party offerings http://www.ezdrm.com/ for playback DRM protection or your own license server http://msdn.microsoft.com/en-us/library/windowsazure/dn223278.aspx.
I have a small solution but I think it will require some work from you, maybe you wont like it that much, how about working with Windows Azure Mobile services. it support adding NPM now, the reason that I am telling you to use the Windows Azure Mobile services is that it will help you connect to your clients whatever was the application platform used.

to integrate between the .Net and Node Js you can start by using Edge JS or signalR I think.
http://www.infoq.com/articles/the_edge_of_net_and_node
http://www.asp.net/signalr
I just want to suggest an idea that might be helpful to work around the lack of support of Media services in Node Js is that you use Blob storage for streaming. after all the Media Services is based on the Blob storage I think. here is a link that will guide you with the usage of the blob storage.
http://www.windowsazure.com/en-us/develop/nodejs/how-to-guides/blob-storage/
here is also a question posted before about how to stream from blob storage using Node JS I hope you find it beneficial.

here is also another link that will help you to do so "Geo-Protection for Video Blobs Using a Node.js Media Proxy"

Just wanted to make sure that you got the Windows Azure Node Js SDK, you might find some solutions that can help you with the development of you application.

I hope my answer helps you let me know if you need anything else.
