I want to render a video file using some images with animation.
I have tried some solution out there and i did not get any solution either I don't know how to write command of FFmpegKit. I also tried to first implement a single image with mp3 but it was also not working.

I would like to generate video content from text/images with provided content size. Have tried many options from FFmpeg to h264 encoders. So a want to build a solution that takes one image or array of images and generate video stream, let's say rtmp. Also image is always changing, adding text, change color etc. I have tried with Golang.
I know that I can access raw video images from the iPhone's camera with AVCaptureVideoDataOutput. I also know that I can record video to a file with AVCaptureMovieFileOutput. But how can I first access the raw video images, manipulate them and then write the manipulated ones into the video file? I've already seen apps in the app store, which do this, so it must be possible.
Ok, I now know, that it's done with AVAssetWriter.
I have an iOS app that I want to record some of its visual output into a video. It looks like the way to create a video on iOS is to use AVMutableComposition and feed AVAssets to it via insertTimeRange.
All the documentation and examples that I can find only add video and audio assets to an AVMutableComposition. Is there a way to add image data to it (i.e. add an image for each frame of the video)? I can get this image data as straight RGB, PNG, JPG, UIImage, or whatever is easiest to feed to AV Foundation (if it's even possible).
If it's not possible to feed images into an AVMutableComposition for the video frames, is there another way to generate an .mp4 file from frames in iOS.
To generate movies from frame you can use AVAssetWriter, here is a question that sort of covers that here on SO, question
I know how to record a video from the camera on the iPhone, my question, is it possible to take the recording and overlay it on a saved video and save it out as another file?
No, I don't think so. Not using an standard framework. You could probably do something involving screen capture and combing a load of images to make a video. But it would be complicated.
I have requirement to record video from the visible view.i,e not form camera. like in TalkingTom application. Can any suggest the solution.
You can take screenshot (using UIGetScreenImage) and store the images into an array.
Then convert it into video using mpeg coder.
