Videorecorder

Videorecorder makes video from your images.

Next frameworks are necessary for Videorecorder work:

• AVFoundation;
• AssetsLibrary.

Videorecorder uses next categories:

• ALAssetsLibrary+CustomPhotoAlbum;
• UIImage+Extras.

All categories ccan be found in the project dir.

Example of use Videorecorder:

VideoRecorder *recorder = [[VideoRecorder alloc]initWithFrames:frameArray andLibrary:nil]; recorder.videoTitle = @"FirstTest"; recorder.delegate = self; [recorder recordVideowithcmpletionBlock:^(BOOL succsess, NSError *error) { NSLog(@"succsess %d\nerror %@",succsess,error); }];

frameArray - it is an array of VideoFrameData objects.

VideoFrameData - it is an object, that contains information about video frame;

• presentationTime - it is a CMTime at which frame should appear at video;

Example: presentationTime = CMTimeMake(0, 1); - frame will be presented at start presentationTime = CMTimeMake(3, 1); - frame will be presented after three seconds of a previous frame;

If we have three frames with times (0, 1), (3, 1) and (5, 1), then first frame will be presented at start, second will be presented at 3 second and third will be presented at 8 second (0 + 3 + 5). Total duration of videofile will be 8 seconds (last frame will has duration == 0). If you want to set not null duration for last frame, then you should add addtional last frame with same image and time which will be equal to duration time.

• img - UIImage;
• libraryAssetURL - url of image in ALAssetsLibrary
• imageLink - link on image eg. in Documents;
