I have an application that broadcast my screen over the network. in other browser it is working correctly but in internet explorer its not working and always shows to download a file instant of playing streaming.
in other browser like chrome
but in internet explorer its not working ....
i have installed many plugin like quick time active x, java etc.
This is difficult to answer without knowing the media type of the streaming.
But I would suggest try installing VLC or the latest media player with updated codecs. Also try disabling any download manager that you might be having.
Note: You can also try the streaming option of VLC as it has a VLC server as well.
Hope that helps.
Also suggested: Buy an authenticated version of Windows or Activate your copy of Windows :P

I'm very new to WSL. I want to run a python code on ubuntu shell on my win10 PC. This code needs access to webcam, but it seems that the webcam is not opened properly..I have checked online and I found several posts 1-2 years ago which said that the integrated webcam cannot be accessed by WSL..Is there any update or trick that can use webcam on WSL?
Many thanks!
You can't still access the webcam in WSL but there are several ways to access the video stream in WSL. The most obvious one is converting your webcam to a web-based streaming protocol like RTSP, MPEG, FFMPEG streams (example) where you get almost similar experiences.
Also, there are many applications where you can make your webcam as an IPcam stream then use the stream URL instead of using the camera index in OpenCV or any other application.
I am trying to make an online examination portal. When students start the exam, their webcam will start automatically and record the stream live and store in the server. Invigilators will either watch the students live or they can watch the saved live streams later.
I researched about this and found WebRTC as a possible solution along with a gateway server like Kurento. But later found out that WebRTC is not supported in Safari, which is a setback! My application should run successfully in web portal in any modern browsers which includes safari and also in android or iphone.
So can anyone suggest a possible solution to my problem? Which technology should I use that can support all browsers and OS?
Also, it would be helpful if you can provide links to good documentation or tutorials.
Note from the future (2020): This answer really isn't accurate anymore.
WebRTC is one problem... capture from the camera with getUserMedia is another. Safari doesn't support either.
There is no video capture API in Safari currently. The only thing you can do is make a native app for iOS.
Worse yet, because of Apple's restrictive policies, alternative browsers, such as Chrome, are crippled on iOS as they aren't allowed to use their own browser engines.
Use standards based technologies like getUserMedia and WebRTC for your primary web-based application. If you decide that the economics of your situation enable it, you can make an iOS app to work alongside until Apple decides to participate in modern browser standards like everyone else.
You can use Mediadevices.getUserMedia (https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) to capture webcam stream on browser (chrome and firefox).
To play with webcam stream on safari, you would have to use a pollyfill - https://github.com/Temasys/AdapterJS
To record the video/audio stream, you can make use of Media recorder api https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder (Note : recording stream is still a challenge in Safari as there is no support/pollyfill. However, it works perfectly on Chrome and Firefox latest versions).

I am trying to setup up video calling in my webapp using Sinch. The application works well on my Chrome (50.0.2661.102 64 bit) but a friend using windows (same version chrome but 32 bit) gets a NavigatorUserMediaError with a reason : DevicesNotFoundError.
I tried using mozilla, vivaldi and IE but non of them works. The error is in the sinch.min.js file and I am using the latest version from their repository : https://cdn.sinch.com/latest/sinch.min.js
Can someone please help me fix these issues?
Also, are there any javascript libraries to help prevent cross-browser compatibility issues while using webRTC.
Thanks
Only WebRTC browsers work with sinch
The NavigatorUserMediaError error with err.name=DevicesNotFoundError is a Chrome specific error and it's quite common. It happens when:
you’re requesting a video track through constraints but the user does not have a webcam
you request an audio track but there is no attached recording device or it's disabled at the OS level (possible in Windows and some drivers do it automatically if there's no microphone inserted in the mic jack)
DevicesNotFoundError will be replaced by the spec compliant NotFoundError in Chrome 64.

I'm currently trying to set up a connection between my web client and my iOS app, but for some reason my iOS client only sees a black box when using Chrome (version 33). I can see the video just fine if I use Firefox (both in my app and when I put the browsers side-by-side, they can see each other).
This doesn't appear to be a documented known issue with the JavaScript SDK, and I can't see any recent discussion about this on the forums (last post was mine).
The iOS sample can be located here (samples/OpenTokHelloWorld) with the browser page in samples/OpenTokHelloWorld/browser_demo.html
I suggest cd'ing into samples/OpenTokHelloWorld and running python -m SimpleHTTPServer, as it can't be run from a file:/// path.
Here is what my iPad sees:
Chrome:
Firefox:
And Chrome/Firefox (respectively), both publishing video from the same camera
Edit: after testing on other machines, it may be something specific to my environment even though none of my extensions run in Incognito and I don't have any custom plugins installed.
It looks like the OpenTok mobile SDKs with the specific webcam I was using has issues. On Android the video stream will display for a brief moment then segfault, and on iOS there will be no video at all.
I have tested this many times and could not reproduce what you are seeing in your chrome.
Without seeing any console errors or iOS logs the best suggestion is to try clearing your cache, or maybe restarting your computer (longshot)
I want to know how to run video present on a sever in windows 8 app.
I am using media element and binding source with the specific url.But video it not playing well if the video is on the local machine it able to play.
thanks in advance for any suggestion
I'd suggest the Player Framework, it works well from my usages with remote videos.
