The idea of the app is that the phone records some footage and on top of that should be a label which changes value throughout the filming process. How can the label be added on to the final movie? Is it possible to directly integrate the label to the movie while recording? Any helpful tips or links will be highly appreciated.
Check AVFoundation's reference of AVAssetWriter.
Besides that, there are plenty examples and questions out there on that component - also here on StackOverflow.

I want to build a Flutter app that allows users to edit videos by pausing at any frame, add shapes such as arrows, circles, or any custom shapes on the video by choosing the shape and add it to the desired position in this frame (the user should add it by finger),this frame will be paused for some specific seconds then the video continue, and save the new video. What is the best way to implement this functionality if possible?
the image below for a pc program clarifies what I want:
video editor for windows
Specifically, I'm looking for suggestions on:
How to add shape annotations to the video?
How to make elongate the edited frame for a specified time
How to save the edited video
Any code snippets, tutorials, or examples would be greatly appreciated. Thanks in advance!
I've tried searching for packages or libraries that can help me achieve this, but haven't found anything specific(i found ffmpeg for flutter but I couldn't find how to use it to add the overlay for specified time and for choosing the position by finger ) . I'm also not sure about the best approach to implement this feature. Can someone provide some guidance on how to proceed?
I am referring this application and want to learn that how can we create like this?
Actually there is the major R&D task for me and I don't even know what to search in this topic.
I don't know , from where to start googling.
According to my understandings, the concepts is, It is getting all frames from video as Image and edit it like draw line on it and then save it, so once video is played it also contains that editing.
I had referred this iFrameExtractor but can't got success.
Please advise me how to start doing R&D on this topic..
Thanks in advance.
Ok i have a answer for your question, First of all u have to get all video from your iPhone. That can be done using ALAssetLibrary after that u have to how thee videos in UITableView. I think that should be easy for u. After selecting a video from a table view u have to play that selected video using MPMoviePlayerController or AVPlayer. After that u have to draw anything.There are number of methods of drawing anything on Videos which are:-
UIBezierPathCurve, UIGraphicsBeginImageContext, Open GLes etc etc
Thats it.try googling on it. thanks :)
I am developing an application where the user has the feature to add frames to the video being captured or to the existing video from the library.
This frames are custom design like the ones in news channel, where the subtitle of the video comes with the name of reporter and so on..
for example
The "Live" tag in the top left of the video..
Can anyone guide me the way how shall I accomplish this, atleast can give me a hint what I can use in this project..
Thanks in advance.
For a video being captured, have a look at the cameraOverlayView property of the UIImagePickerController.
I try to display two different http/rtsp-Video-Streams at the same time on the same UIView.
So my first thought was to use the UIViews of two MPMoviePlayerController.
But the documentation says:
Note: Although you may create multiple MPMoviePlayerController objects and present their views in your interface, only one movie player at a time may play its movie.
Okey!
My second thought was to use the UIWebView.
But that also doesn't work. I can display only one stream.
I hope you can help me.
Best regards.
On iPhone, as the documentation says, only one Video can be shown at any point. Video has to be full Screen! check also:
Customizable non-full screen video player in iPhone
I'm wanting to put together an application which plays video fullscreen with an interface overlaying it that basically chooses the video that is played underneath it (think 'Gym Babes' but nowhere near as risqé!). I don't wish to use private headers so MPMoviePlayerController is out of the question.
I've been digging through stackoverflow for a while and have come to the conclusion that I would need to use some sort of custom codec/video library that I assume would be written in C.
My question is basically has anyone had success doing this? And can anyone share any code, tutorials etc they can share?
You probably want to take a look at AVPlayerLayer: http://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVPlayerLayer_Class/Reference/Reference.html it gives you basic playback abilities with no (read fully customizable) interface…
