React Native - display camera roll videos

Question

My RNCameraRoll videos and photos are saved on my custom folder in my device, I want to display the videos in my app...I used getPhotos method to display or create my photo gallery, but for videos it displays only images.

setIndex = (index) => {
        if (index === this.state.index) {
            index = null
        }
        this.setState({ index })
    }

    getPhotos = () => {
      CameraRoll.getPhotos({
          first: 20,
          groupTypes: 'Album',
          groupName: 'Vocajam Videos',
          assetType: 'Videos'
      })
      .then(r => this.setState({ photos: r.edges}))
  }

I tried using video package to play the videos, but I discovered all the videos where playing at the same time, and there were no visuals, my screen is blank, only audio was playing.

What am I doing doing wrong. Please your help will be appreciated, thanks in advance.
