is it possible to stream (previously recorded and/or live) video to many Microsoft Lync SDK webbrowser clients?
Thanks in advance,
Etam.
The short answer is No - not without some pain. The long answer depends on your exact scenario.
If you can control the client build, and are able to ensure Lync is installed, then you should be able to automate Lync from the Silverlight app to connect to the conference that is hosting the video content you want to display. With this solution, it will be Lync that's actually displaying the video, not Silverlight. That's pretty simple, and covered in the Lync SDK.
Otherwise, you'll have some work to do. I'd imagine that you could put together a solution using UCMA 3.0 to build a Lync application to control a conference and get access to the video stream, then stream that to the Silverlight clients using IIS Live Smooth Streaming or something similar. This wouldn't be real time video, so there would be a slight delay, but if your video is one way only (e.g. lectures being consumed by students), then that shouldn't be a problem.
It's worth bearing in mind that this is not a solved problem yet (at least, within MS) as even the Lync Web App (the official Silverlight Lync Client) does not support video.

YouTube recently forced everyone to the new YouTube studio for live streaming. Per their documentation here https://support.google.com/youtube/answer/2853812?hl=en the only place to setup Multiple Camera angles is on the Events page. However, since their change I can't access Classic Streaming anymore, it just pop ups a message saying
Live Control Room is the new way to go live.
I've tried reaching out to YouTube directly - I'm stuck in a support loop of uselessness. Has anyone else seen this and found a workaround?
Direct email from YouTube:
I just want to make all a clarification regarding your concern why you can't find to stream with multiple camera angles.
Due because of low usage and since it can't be watched on mobile,
multi-camera won't migrate to Live Control Room right now. Rest
assured we are looking for a better version of this product in the
near future.
We also recommend you to send a feedback to our Product team so they
can look into your suggestion.
Thanks for your understanding on this matter. Let me know if you have
other questions.
WebRTC requires too much processing power on server so doing it massively will be cost-prohibitive.
For nearly all other platforms - both for Windows and Mac - Chrome, Safari desktop, even IE and Edge, and Android - there is a Media Source Extensions API (https://en.wikipedia.org/wiki/Media_Source_Extensions) which allows sending stream over websockets and play it, it works. Problem is just with iOS.
Is there anything better (lower latency) than HLS which would work for me?
If not, is there a WebRTC server which is free and better scalable/more stable than Kurento Media Server (https://github.com/Kurento/kurento-media-server)?
There is a jsmpeg player http://jsmpeg.com/ but it is MPEG-1 only so will require unacceptable amount of bandwidth. There is broadway.js but it does not support audio...
Is there anything better (lower latency) than HLS which would work for me?
HTTP Progressive is a fine technology for this. It can be ran at much lower latencies than a segmented technology like DASH or HLS, and requires very little in terms of server-side resources. Look into Icecast for your server, and FFmpeg as your source.
There's no point in sending video over Web Sockets, unless you're implementing a bi-directional protocol. This isn't uncommon for ABR support, but it's definitely not the most efficient or simple way to do it.
Since you don't want to implement webRTC by yourself and need lower latency than HLS, I would prefer a media server. There are many media servers available in the market. But if you are looking for free and open source media server, your options are limited to few.
I would suggest red5 media server which is free and open source. Please check this link to find more about red5. If you use free red 5 media server you need little knowledge of java. Red5 also has a paid version called red5 pro which has better webRTC support and higher capabilities. Red5 is mostly for rtmp with flash player pulgin and its fairly new for red 5 webRTC streaming.
Also you can use wowza streaming engine trail version with limited number of connections. So these are the easiest options for you.
I want to stream live video from my website. This website will be basically for a TV Channel which hosts shows 24 hours. So, this video will stream live for 24 hours like some sports channel. So, If anyone have some idea of Streaming video wholeday from my own website, please tell me.
I have searched and found out solution for encoder as Teradek Vidiu and Software solution as DaCast and UStream.
But, I did not find DaCast or UStream useful for providing stream from my website for whole day. They are useful when I want to go for any event streaming. I Can also go for Developing my own RTMP Server, but i found that it will have security issues then.
You could use MonaServer. I'm the co-author of this project, it is a media server that is well suited for real-time streaming as it implements RTMFP (no more security issues than other solutions). It is already used by TV channels. You can develop your flash client or ask us to build it.
You can try publishing with this sample : http://raspi.monaserver.ovh/MonaClients/VideoPublisher/
And reading with this one : http://raspi.monaserver.ovh/MonaClients/VideoPlayer/
And you can use Netgroup for P2P streaming if you have limited bandwidth.
There is a free nginx-rtmp module for NGINX fast web server, which supports recording, on-the-fly encoding, RTMP broadcasting, authorization and statistic page.
We used it in an online education project for video recording and it worked good.
https://github.com/arut/nginx-rtmp-module/wiki
According to our tests - works much better and faster then other opensource Red5 or crtmpd servers. Good opensource RTMP server alternative.
Been having trouble with YouTube lately with regards to autoplay, looping and playlists. Currently using the AS3 embedded player and it was working fine until recently when autoplay and playlist options became mutually exclusive. I am also finding the loop option doesn't work with autoplay.
So, looking at options other than YouTube as we will have access to the video anyway and can either upload or stream using whatever technology is appropriate. My application is for touchscreen interactive kiosks which will be largely unattended and I want to be able to run embedded video with all controls turned off to prevent anyone from jumping off to some other website at any point. This is crucial! I don't mind if a touch can pause the video like it does with YouTube but links must not be available to jump out.
My web app is written in Rails 3 with HTML, CSS3 and JQuery where required. It runs on IE8/9 on the kiosks and Safari mainly during development. I'm using Heroku.com for hosting.
Hopefully I've given enough background here to attract some good answers but please let me know if I've missed anything important.
Thanks for your time,
Craig.
This service is awesome in quality and price.

If you are using heroku for your hosting, you should take advantage of their add-on. The interface is super clean and you have full flexibility to mold playlists or behavior.

Just got a car with the Microsoft sync system in it. Did a quick search online and was curious if anyone is aware of any SDK that may exist, sample open source add-on applications, etc.
Thanks in advance.
UPDATE:
Looks like Ford has finally released their SDK:
https://developer.ford.com/
Ford has a website SYNC Mobile Application Developer Network but the SYNC SDK does not look to be available yet (their site mentions possibly later this year). It appears they are stilling working on the API before releasing it. All they are offering now is a way to register to be notified of new info as it becomes available.
From their About page:
Ford is hard at work developing an API
to allow developers to integrate their
Smartphone applications with SYNC. The
Developer Program website will educate
developers about the Ford SYNC
platform and how to interact with it
via the API. There will be a full set
of documentation, example
applications, reference libraries, and
even a developer forum so you can
reach out to the community for quick
help.
With the available SYNC API's, mobile
application developers will be able to
do some of the following:
Create a voice UI for your application using the in-vehicle
speech recognition system.
Write information to the radio head display or in-vehicle touchscreen
Speak text using text-to-speech engine.
Use the in-vehicle menu system to provide commands or options for
your mobile application
Get button presses from the radio and steering wheel controls.
Receive vehicle data (speed, GPS location, fuel economy, etc.)
The official API and full website
launch is set to be targeted for later
this year.
It looks like the SDK is coming very soon. The story was just posted on Engadget:
http://www.engadget.com/2009/12/18/ford-to-give-sync-some-app-store-flavor-opening-api-to-devs-in/
Now just imagine what you could do with access to your automobile functionality!
I don't think there is any. Its a closed ecosystem.
http://www.autoblog.com/2009/01/09/ces-2009-sync-could-one-day-add-app-development-like-iphone/
From what I understand it is based on the CE 6.0 platform using windows automotive 4.1, but I could be wrong. We really need a forum to get this going. Hurry up Ford! Release the SDK!
Given the way Windows automotive is there is only two ways of putting a ROM on Sync. Using JTAG to put your own custom bootloader (forget it), or though the USB. Which you will need to know how to sign the file so sync will think it is an OEM ROM. So at this point even if you were able to come up with your own custom rom by using Microsoft eMbedded Visual C++ you would still have no way to get it on there.
BTW, the SDK they are talking about releasing will only be to develop apps for applink. (not modifying the OS). However, to upload the apps we might be able to find out how to sign the .bin file for sync to accept a ROM through the USB.
Then again this is just from my understanding... I am no great developer or anything.
