avassetexportsession

I'm encountering wrong orientation of video exported using AVAssetExportSession only in front Camera. I followed this tutorial https://stackoverflow.com/a/35368649/3764365 but I got this scenario. I think it's not wrong orientation the image is cut at half. I tried changing the video layer, render layer but got no luck. My code looks like this. let composition = AVMutableComposition() let vidAsset = AVURLAsset(url: path) // get video track let vtrack = vidAsset.tracks(withMediaType: AVMediaTypeVideo) // get audi trac let videoTrack:AVAssetTrack = vtrack[0] _ = videoTrack.timeRange.duration let

After I export an AVMutableComposition I use PHPhotoLibrary to save the video to the camera roll. In the creationRequestForAssetFromVideoAtFileURL: completion handler, I then open the saved video in Instagram, like so: __block PHObjectPlaceholder *videoAssetPlaceholder; [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ PHAssetChangeRequest *req = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:localVideoURL]; videoAssetPlaceholder = req.placeholderForCreatedAsset; } completionHandler:^(BOOL success, NSError *error) { if (success) { completion(YES); NSString *localID =

In my iOS application I'm trying to export an mp3 file from the iPod library to the app's documents directory on the device. Currently I'm trying to use AVAssetExportSession but it's not working for mp3 files. It works well for m4a files. Is exporting an mp3 file possible using AVAssetExportSession? What is the appropriate outputFileType for AVAssetExportSession? ( AVFileTypeAppleM4A works for m4a files) Thanks! urish I am facing the same problem. Unfortunately, non of the iOS frameworks (AVFoundation, CoreMedia, etc) support encoding to MP3. An answer to a similar question suggest using the

I am now trying to export an mp3 file that has been player using AVPlayer (using an url) so it doesn't have to be downloaded twice. This is my sample code: I've tried every outputFileType... self.exporter = [[AVAssetExportSession alloc] initWithAsset:self.asset presetName:AVAssetExportPresetPassthrough]; } NSError *error; NSLog(@"export.supportedFileTypes : %@",self.exporter.supportedFileTypes); // "com.apple.quicktime-movie", // "com.apple.m4a-audio", // "public.mpeg-4", // "com.apple.m4v-video", // "public.3gpp", // "org.3gpp.adaptive-multi-rate-audio", // "com.microsoft.waveform-audio", //

I start saying that I spent a lot of time searching through documentation, posts here and somewhere else, but I can't figure out the solution for this problem. I'm using AVAssetExportSession for exporting an .mp4 file stored in a AVAsset instance. What I do is: I check the isExportable property of AVAsset I then get an array of exportPresets compatible with the AVAsset instance I take the AVAssetExportPreset1920x1080 , or, if not existing I try to export the media with AVAssetExportPresetPassthrough (FYI, 100% of times, the preset I need is always contained in the list, but I tried also the

I'm trying to merge (append) 3 videos using AVAssetExportSession, but I keep getting this error. Weirdly for 1 or 2 videos it worked. Error Domain=AVFoundationErrorDomain Code=-11820 "Cannot Complete Export" UserInfo=0x458120 {NSLocalizedRecoverySuggestion=Try exporting again., NSLocalizedDescription=Cannot Complete Export} I even tried to redo the function in case of error but what I got is only infinite error message. This is the snippet of my code. AVMutableComposition *mixComposition = [AVMutableComposition composition]; AVMutableCompositionTrack *compositionTrack = [mixComposition

I'm trying to merge some audio files (picked via MPMediaPickerController), but the export always fails with error code -12780. When I try to play my composition with an AVPlayer object, it plays correctly. Just the export fails. What am I doing wrong? This is my code: AVAssetExportSession *exportSession; AVPlayer *player; - (void)mergeAudiofiles { // self.mediaItems is an NSArray of MPMediaItems if (self.mediaItems.count == 0) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"No Tracks selected." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert
