How to add custom transition on video: Hello I am trying to add transition b/w video clip using AVMutableVideoCompositionLayerInstruction i am able to add only simple transition and not able to add any complex transition like ripple, reveal and etc.
Please guide me how to add complex transition b/w video clip.
Code snippet for Simple Transition b/w Video Clips:
AVMutableVideoCompositionLayerInstruction *fromLayer;
AVMutableVideoCompositionLayerInstruction *toLayer;
if (i+1 < [ClipPath count])
// Add transition from clip i to clip i+1.
AVMutableVideoCompositionInstruction *transitionInstruction = [AVMutableVideoCompositionInstruction videoCompositionInstruction];
transitionInstruction.timeRange = transitionTimeRanges[i];
fromLayer = [AVMutableVideoCompositionLayerInstruction videoCompositionLayerInstructionWithAssetTrack:compositionVideoTracks[alternatingIndex]];
toLayer = [AVMutableVideoCompositionLayerInstruction videoCompositionLayerInstructionWithAssetTrack:compositionVideoTracks[1-alternatingIndex]];
if ([transitionType isEqualToString:@"Multi-Push"]) {
if(i== 0){
[fromLayer setTransformRampFromStartTransform:CGAffineTransformIdentity toEndTransform:CGAffineTransformMakeTranslation(videoWidth, 0.0) timeRange:transitionInstruction.timeRange];
}
else if (i == 1 )
{
[fromLayer setTransformRampFromStartTransform:CGAffineTransformMakeTranslation(0, 0) toEndTransform:CGAffineTransformMakeTranslation(0,0 - videoHeight) timeRange:transitionInstruction.timeRange];
}
else if (i == 2 ){
[fromLayer setTransformRampFromStartTransform:CGAffineTransformMakeTranslation(0, 0) toEndTransform:CGAffineTransformMakeTranslation(0,videoHeight) timeRange:transitionInstruction.timeRange];
}
else{
[fromLayer setTransformRampFromStartTransform:CGAffineTransformMakeTranslation(0, 0) toEndTransform:CGAffineTransformMakeTranslation(0 - (videoWidth),0) timeRange:transitionInstruction.timeRange];
}
}
}
Help in either Swift or Objective C Appreciated.
Thank you in advance
