Video List by RecyclerView made simple. Auto play/pause supported with smart caching last playing position.

Toro

Auto playback on Video list made easy, special built for RecyclerView

1. Introduction and motivation

• Add Auto playback on scrolling features like Facebook App or Twitter App into your App by Toro:

  • Easy to use. Target Android SDK from 16 up (I hate the rest, sorry).
  • Adding support layers on tops of RecyclerView's LayoutManager/Adapter/ViewHolder.
  • Transparent code with original RecyclerView. Provide useful methods set on top of them. See ToroAdapter, ToroAdapter$ViewHolder.
  • OUT-OF-THE-BOX usability: just extends my pre-coded classes, I have prepared the rest for them. See ToroVideoViewHolder and its relatives
  • Highly customizeable: use can custom almost the important logic parts, Toro listens to your changes.
  • Video Player lifecycle: Toro listen to Activity's life cycle to init/release its resource. Further more, Toro creates and supports Playback Lifecycle which is super helpful for those who want to catch up with the playback progress as well as update UI before/after playing. All of those features are usable out of the box. See Video Player lifecycle.
  • Super easy to setup: see usage section.

• There are some other working ideas, but those libraries have different approaches, which are in my oppinion, not as good as I expected: User of those libraries need to re-write a lot of code to match their implementation. I try to make our components as close to official RecyclerView/Adapter/ViewHolder/LayoutManager as possible, and just provide some useful methods on top of them.

• I drop supporting for ListView/GridView since those components are obsolete and hard to maintaince. But I made a on-going branch which provide some code base with the same thinking with the rest of this library. So any one can take a look and create their own helpers.

2. Main features:

• Auto start/pause/resume by scrolling your RecyclerView, support all Layout managers. Last-minute caching: Toro remembers last playback position and resume from where you left (note that: in Android default Media Player, depend on Video's format and codec, the resume timestamp may varies).

• Playback behavior decided by User, not by library:

  • Customizable Strategy to decide which is the best component to start playback. Optimized built-in Strategies to help you start.
  • UI-based logic, straight-forward approach: you see the Video, then it should play. Default: you see 75% of the Video then it should start playing. Advance: you decide how much the visible Video should trigger the playback.
  • Decision from both side: Toro's core and your components. Toro listen to your components: does it want to play, is it able to play (well-prepared or had error), then Toro's strategy will decide if it allows your component to play or not. Default: built-in Strategy and components do the rest. Advance: you have control to the both side.

• Built-in widgets: an abstract ViewHolder for original VideoView, an abstract ViewHolder for "TextureView version" of VideoView: TextureVideoView, and an abstract ViewHolder for my customized version of TextureVideoView: ToroVideoView, with more flexible API and less annoying error processing.

• Powerful, flexible and highly customizable API. See Wiki for more details.

• Selective playback: find the best playable item, defined by smart, flexible Strategies to decide when and how a player should start playing. Toro comes with optimized built-in Strategies, but user could always create their own. See Wiki for more details.

• Smartly support Grid (with many Video in one window) by built-in Long press listener. Turning ON/OFF in one line of code. See Wiki for more details.

• I create lots of built-in code, but keep Toro highly customizable. You are free to decide how you want to start your player, but if you don't know, just let Toro help you to decide.

See Wiki for more details.

3. Toro in Action

4. How to use

0. Prerequirement

• From Android SDK level 16 (4.1)

1. Add Toro to your project

• Add this to Project's top level build.gradle

allprojects {
	repositories {
		maven { url "https://jitpack.io" }
	}
}

• Add this to dependencies

dependencies {
	compile 'com.github.eneim:Toro:1.1.0'
}

TL,DR: app module from this library comes with several good practice of this library. Please take a look.

2. Integrate Toro into your Application: see Toro starting guide

3. Register/Unregister a RecyclerView to get support from Toro: see Register/Unregister RecyclerView to Toro

4. Create ViewHolder to use with Toro: by default, just simply extend one of ToroVideoViewHolder, TextureVideoViewHolder or AbsVideoViewHolder. See ToroViewHolder for more information.

• A sample ViewHolder's code (see Sample app for more):

public class DeadlySimpleToroVideoViewHolder extends ToroVideoViewHolder {

  public DeadlySimpleToroVideoViewHolder(View itemView) {
    super(itemView);
  }

  @Override protected ToroVideoView findVideoView(View itemView) {
    return (ToroVideoView) itemView.findViewById(R.id.video);
  }

  @Nullable @Override public String getVideoId() {
    return "my awesome video's id and its order: " + getAdapterPosition();
  }

  @Override public void bind(@Nullable Object object) {
    if (object != null && object instanceof SimpleVideoObject) {
      mVideoView.setVideoPath(((SimpleVideoObject) object).video);
    }
  }
}
