Takes a video asset and reverses it, puts it in a AVMutableComposition and exports it as a .mov file.
The exported file becomes available in iTunes under File Sharing ( [iOS Device]/Apps/ReverseClip).
##How to implement? Just copy the folder “RCToolbox” to your project.
Import the class “RCToolbox.h” in your class.
RCFileHandler *filehandler = [[RCToolbox sharedToolbox] fileHandler];
AVURLAsset *myAsset = [filehandler getAssetURLFromBundleWithFileName:@“[asset]”];
[self preExportForImageSequence:myAsset];
-(void) preExportForImageSequence:(AVURLAsset *)_asset
{
RCComposer *compositionTool = [[RCToolbox sharedToolbox] compositionTool];
[compositionTool addToCompositionWithAsset:(AVURLAsset*)_asset timeRangeSpeed:kTimeRangeSlowMotion inSeconds:0.0 outSeconds:2.0 isForImageSequence:YES speed:kTimeRangeSlowMotion];
}
In this case you will probably use CMTimeZero for inSeconds and asset.duration for outSeconds.
##Tweak it To change the width and height of the clip, change the constants in RCImageSequencer.m
You might want to comment out NSLog(@"Percentage done: %f",percentageDone); in the same class.
##How does it work?
