rn-video-slider

A dedicated progress slider for video player's custom user interfaces in React-Native. It can also be used in audio players because why not? 😎

Why this module?

• superior performance thanks to Reanimated library
• clean and simple implementation that makes it easy to extend
• integrated buffer indicator for online streams
• fully written in Typescript
• easiest way to use
• RTL support

Installation

This module uses react-native-reanimated and react-native-gesture-handler as peer dependencies. make sure You have installed them correctly. You may also install react-native-video. Check out these links to proceed their installation process:

• reanimated installation
• gesture-handler installation
• video installation

Once you are done with above, add the main package with one of below commands:

using npm

npm i rn-video-slider

using yarn

yarn add rn-video-slider

That will be it.

Usage

import {Dimensions} from "react-native";
import Slider, {ISlider} from "rn-video-slider";

const ControlSet = () => {

  const sliderRef = React.createRef<ISlider>();
  //call below function in video progress callback
  //sliderRef.current?.setProgress(0.5);

  const _onSlide = (value: number) => {
    //seek your video with value
  };
  
  //this simply means 80% of screen's width
  const sliderWdith = Dimensions.get('window').width * 0.8;

  return (
    <Slider
      ref={sliderRef}
      width={sliderWdith}
      onSlide={_onSlide}
    />
  )
}

Note: You can see the Component in action by cloning this repo and building its test app. Just head over to testapp directory, install the dependencies and run it on Android or IOS.

Known issues

Tapping the Slider on Android will cause it to bounce back and forward sometimes. I've seen this issue being reported in community as well, yet I haven't found a certain solution to fix it. It's also not clear to me that whether it should be fixed at this side or Exoplayer's side.

TODO list

• workaround bouncing issue on Android (maybe)
• add hovering bubble feature
• add in-code docs
• ensure fabric support
• more and better demo gifs
• cleanups and refactors
• bump test-app dependencies up
• write a better example
• fix delay between thumb and track while sliding fast
• implement tap to seek feature
• replace the deprecated useAnimatedGestureHandler with newer API
• add style prop for root view

Contributions

If you have any idea to improve or fix something, open an issue and state it in details. You will always be welcomed.

Compatability

• react-native-reanimated: 2.x, 3.x
• react-native-gesture-handler: 2.x

Acknowledgement

The idea behind this is from react-native-reanimated-slider. Since the mentioned module is written with Reanimated v1 API, and hasn't been updated for a long time, I decided to remake it.
