I want to get a image of web page from Safari not Safari application screenshot.
I try to capture this by CGWindowImageList? function but this function capture application screenshot.
Try and load up the page in a UIWebView and drawing the view onto a buffer unless you specifically need to capture a running Safari session. This is what Paparazzi does, if I recall correctly.

How to edit the extension to be as I want
Thanks
No its not possible to do within browser, its the matter of end user privacy.
You can build your own native Windows/Mac application to get rid of this
Chrome is providing screen/window/tab capturing through chooseDesktopMedia API, it is available only from chrome extension and we cant call this API from web app.
That demo extension is showing how to use chooseDesktopMedia.
We have no control on the screen selection popup, we can only choose the
combination of screen/window/tab/audio with the DesktopCaptureSourceType
I'm running appjs and I'm thinking of showing live content from the local webcam in the html and would like some hints on how to do this.

Appjs is built on top of CEF so I think I am correct in saying that at the moment this functionality is not available out of the box. However the next version of AppJS will use content api which means that media and video should be available.
For now I would suggest that you develop your application in HTML5 using chrome and then run it inside AppJS later on when it catches up and provides these functions out of the box.
For one of my apps I'd like to send the app to snapped view after tapping a button. As far as I know there's no public API available to send a running application to snapped view. Did anyone find a workaround to do this?
Somehow it should be possible since you're able to do it in Windows 8 itself, and snap one of the running apps.
Update: Being able to trigger a Win+. might do the same trick, but the SendKeys API isn't available in WinRT either.
There is no way to force an application into snapped mode - it has to be a user initiated action.
An application can request to be unsnapped through:
Windows.UI.ViewManagement.ApplicationView.TryUnsnap();
Which tries to push the app into fill mode.
Windows 10 has a ApplicationView.TryResizeView method
So... to summarize the interesting WinRT journey:
Windows 8
Has a a 'Snapped' mode that a only a user can initiate. the developer can try to unsnap with the TryUnsnap method
Windows 8.1
Does not have Snapped mode, and TryUnsnap is deprecated. The dev can still listen for window size changes and know if the app view is in a smaller size as before.
Windows 10
Introduced the ApplicationView.TryResizeView method, where the dev can try to resize. Window size changed event is still there.
ApplicationView.GetForCurrentView().TryResizeView(new size(width, height)));
Is it possible to capture a snapshot of a video that's loaded using the HTML5 video element and use that as a preview image until the video loads or the play event is triggered? I know about the poster attribute but I want the thumbnail to be self generated, like a random frame from the video. Sort of what YouTube/Vimeo does.
Thanks,
I don't think that this is possible in pure HTML5. Principally because the stream is not loaded when you see the 'object' in the webpage so the client can't get the desired frame.
However, the best option for you is to save / cache the 'random frame' before loading the page and then use it as the poster of the video. This will allow you to reduce the client work and save the bandwith.
check THIS, which is the first thing that I've found (if you're using PHP and you want a 'quick and dirty' way to get the frame)
Update
Apparently HERE there is a solution with popcorn.js BUT it seems that you can't do it in the way that (I suppose) you need.
This because it would be possible to do this only inside the same domain due to browser security issues.
I have uploaded a couple of tutorial videos in youtube.
In my winforms application (by using the AxShockwaveFlash object) i reproduce the selected video by the user.
AxShockwaveFlash1.LoadMovie(http://www.youtube ..video1)
Here comes the story.
The first time the user selects a video, reproduction works like a charm.
When the user selects to see the second video
AxShockwaveFlash1.LoadMovie(http://www.youtube ..video2)
the ShockwaveFlash continues the reproduction of the first selection
Try to use
AxShockwaveFlash1.Stop();
AxShockwaveFlash1.Movie = "Your source";
AxShockwaveFlash1.Play();
Pattern to avoid leaving flash arguments behind.
Without knowing how you have integrated the video in your form, the method I would do is using a webBrowsercontrol in the form and embed the video in the control.
msdn on webBrowsercontrol
I had encountered this problem and resolved it by changing the Embed property of the Ax object control to False.
I embed the videos via the movie URL each time as follows:
http://www.youtube.com/v/targetmovie&feature=player_embedded
Works a treat
Tamir,
the video is embedded. Not stored locally
This is because your application is loading flash player loader from the cache and then it's loading the real player from the site , finally this yield a security exception.
In internet explorer , in internet options set to check for new versions of the documents each time you visit the page.
You first need to extract the FLV file like here:
