I tried using the following code from http://codethink.no-ip.org/wordpress/archives/673 then putting it into the The OpenTokHello sample app from OpenTok and it appears to not actually record the video as I thought it would.
I made the ScreenCaptureView the new "superview" of everything and then made sure that the video streaming views would be added to that view. And when I played the video, the place where the streaming video should've been, was blank.
Any ideas on what I'm doing wrong?
Full disclosure: I wrote some of the OpenTok iOS SDK and work for TokBox.
The implementation of this ScreenCaptureView might not work with our SDK because all of our video rendering is done outside the context of UIView. You'd have to grab the rendering layer of the view in order to recover that part of the screen.
Depending on why you're trying to record the conversation, I recommend either
Using screen capture in QuickTime and running your app in simulator (easier)
Waiting for OpenTok archiving support on iOS which will be available in a few months (also easy, but not for the impatient)
Capturing the rendering output of the subscriber from CoreGraphics (less easy)

Want this feature in flutter (android/IOS)
I want to keep the video playing when an app goes to the background and shows a player controller in the notification.
Is this possible?
You can try this library https://pub.dev/packages/just_audio with the latest version 0.9.21. It's quite easy to configure though some features are still experimental e.g Simultaneous downloading+caching, Background play which are here Experimental features. Overall it works for me.
I have searched everywhere and tried mixing and matching different bits of code but I haven't found anything that works or anyone with the same question.
Basically I want to be able to create video demos of iPhone apps that include standard UIKit elements and also the image coming from the camera (video preview layer). I don't want to use airPlay or iOS simulator to project onto the desktop then capture because I want to be able to make videos outside in public. I have successfully been able to video capture the screen with this code but with the video preview layer being blank. I read that its because its using openGL and what I'm capturing is from the CPU, not the GPU. I have successfully used GPUImage from Brad Larson to capture the video preview layer but it doesn't capture the rest of the UIView. I have seen code that combines both and converts to an image but I'm not sure if that would be too slow for realtime video capture. Can someone point me in the right direction?
It might not be the cleanest solution, but it will work nonetheless: did you consider jailbreaking? I hope Apple does sue me for this one but if you really want to record your screen then simply install a screen recorder. Enough options can be found: http://www.google.be/search?q=iphone+jailbreak+record+screen
And if you don't like it: recover your phone for a previous backup.
(for the record: I'm against jailbreaking and posting this from a productivity point of view)
I am currently using iwebkit and phonegap together. Once everything is compiled and tested on an idevice, I can click a video link and get it to play. It play full screen but it uses the ios web video player (the one that doesn't have the "done" button" and the top and has a bar that spans the bottom of the screen. I can then press the full screen button to have it use the regular ios media player but when i click done from that, it doesn't take me back to the part of the app before the video, it just takes me to the full screen video in the web player. I hope someone can help me solve this and I hope I was able to describe my problem in a clear way. I've spent 2 hours searching and have come up with nothing.
I'm having the same problem. iOS 4.3.x introduced this problem as far as I can tell. There's a few comments about it on Apple's developer site but so far I haven't found any solution. Part of the problem seems to be Phonegap because I experience the exact same thing you describe when running the compiled app. However, if I simply browse to the same HTML pages it seems to work fine. Note - I changed from directly linking to video files to using the HTML5 tag. Using the tag works better than direct linking in Phonegap -- the videos still open in the player but when you click the Done button it returns to where it was. Keep in mind that if you do this the video will be on the inline in the page and paused but when you click the play button it opens in the player. The only problem I've found with this solution is that it won't rotate when you change from portrait to landscape when running in the phonegap app but it does rotate when browsing to the video in mobile safari. Not sure if any of that helps. I would be interested in what you've been able to work out since you posted.
I'm writing an iPhone App that allows people to share images that may be copyrighted(not illegally). The issue I am having is that I'm looking for a way to work around the screen capturing. Is there any possible way you can disable screen capturing or possibly distort the image in some way so capturing will be useless, maybe even block the images when a screen capture is trying to be taken?
That is impossible because it is embedded in iOS itself. Maybe some private APIs, but then there is no app store for your app.
Watermarking the images may be a good half-way solution.
iOS screen capture does not support capturing everything. It does not capture OpenGL or YouTube for example. So if you can manage to implement showing images using OpenGL instead of the simple way using UIKit they would not show up on a screen shot.
When we call MPMoviePlayerController.play method, the movie player is opened and the video is played in a separate full screen. is it possible to play a video in a custom view, that is I have an image added on a view, when this image is clicked, the image has to be removed and the video has to play there itself as the feature in iPad.
Non-full screen playback of video is possible in iPhone OS 3.2 for iPad.
If you are porting an application that uses the MPMoviePlayerController class of the Media Player framework, you must change your code if you want it to run in iPhone OS 3.2. The old version of this class supports only full-screen playback using a simplified interface. The new version supports both full- and partial-screen playback and offers you more control over various aspects of the playback.
On the full-screen question, see this section of the iPad Programming Guide for further information, and this property of MPMoviePlayerController specifically.
Bear in mind that you can still only play one video at a time, and that this is only currently possible for iPad.
Not using MPMoviePlayerController, no.
You might be able to achieve this using a custom movie player, but I haven't seen one in the wild yet, and I don't know how it would be done.
