avassetwriter

I'm trying to record video with AVAssetwriter but I keep getting NO when checking AVAssetWriterInput property readyForMoreMediaData before appending data. I saw related posts that mentioned similar problem when trying to record audio + video so I took out the audio recording part but the problem still occurs ( readyForMoreMediaData is always NO). My code: - (void)startRecordingWithAssetWriter { NSLog(@"Setting up capture session"); captureSession = [[AVCaptureSession alloc] init]; //----- ADD INPUTS ----- NSLog(@"Adding video input"); //ADD VIDEO INPUT AVCaptureDevice *videoCaptureDevice =

AVAssetWriter startWriting is returning BOOL False value when i'm writing movie on 2G device, but for all other devices its returning TRUE value and working fine.Anyone faced this problem or do you have any clue why its happening,help me please I am receiving false on startWriting on an iPad, when it works on both my iPhone3 and 4 (all have iOS 4.2).

I am making a sample application that utilizes AVFoundation to record video. The whole point is so I can have more control over how the video is recorded. In my sample project I have the video capturing but am struggling with handling orientation correctly. I have done a lot of searching around the web and found that others are suggesting that I should NOT allow my capture view or capture session to rotate based on orientation, but rather set a transformation to rotate the video during playback. I have this working fine on iOS and Mac devices, but am wondering if I will have issues on other

I have a project that currently uses the H.264 encoder to record video on iOS. I wanted to try using the new HEVC encoder in iOS 11 to reduce file sizes, but have found that using the HEVC encoder causes file sizes to balloon enormously. Here's a project on GitHub that shows the issue - it simultaneously writes frames from the camera to files using the H.264 and H.265 (HEVC) encoders, and the resulting file sizes are printed to the console. The AVFoundation classes are setup like this: class VideoWriter { var avAssetWriterInput: AVAssetWriterInput var avAssetWriter: AVassetWriter init() { if
