# 📽 VideoEditor
*VideoEditor* facilitates video editing
## Requirements
- iOS 9.0 or later
- Xcode 11.0 or later
## Install
### Installation with CocoaPods
```ruby
pod 'VideoEditor', '1.1'
```
### Build Project
At this point your workspace should build without error. If you are having problem, post to the Issue and the
community can help you solve it.
## How to use:
```swift
import VideoEditor
```
### Merge multiple audios to a video.
1: Prepare the source video asset.
```swift
let videoAsset = VideoEditor.Asset(localURL: yourVideoLocalURL, volume: 1)
```
- With `volume`, you can able to adjust to volume of video in 0...1
2: Prepare the audios
```swift
let firstAudioAsset = VideoEditor.Asset(localURL: firstAudioLocalURL, volume: 0.5, startTime: .zero, duration: videoDuration)
let secondAudioAsset = VideoEditor.Asset(localURL: secondAudioLocalURL, volume: 0.7, startTime: CMTime(seconds: 2, preferredTimescale: CMTimeScale(NSEC_PER_SEC)), duration: secondAudioDuration)
```
- `startTime` is the point of time that you wanna add your audio into the final video, e.g. add set `startTime` as `CMTime(seconds: 3, preferredTimescale: CMTimeScale(NSEC_PER_SEC))` to tell engine to start add this audio from the third second of the final video.
- `duration` indicates how long the audio will be added into the final video from the `startTime`. Usually set it equal to the audio asset duration. Set `nil` to tell the `duration` is its duration.
3: Start to merge
```swift
let videoEditor = VideoEditor()
videoEditor.merge(video: videoAsset, audios: [firstAudioAsset, secondAudioAsset], progress: { progress in
print(progress)
}, completion: { result in
switch result {
case .success(let videoURL):
print(videoURL)
case .failure(let error):
print(error)
}
})
```
