# ExoPlayerTimelineView

If you already use ExoPlayer in your project and need to extract video

frames and show them as a **timeline view** either scrollable or in a

fixed-width mode then you're in the right place.







You might already be familiar with `MediaMetadataRetriever` api and its

`getFrameAtTime(..)` method, I included adapter implementation(it's not

meant for production use) for comparison with `RetroInstance` API, which

caches frames internally and won't init any mediaCodec resource if

unnecessary. And it's running significantly faster.

### Installation

Add this to your application module, inside *dependencies* block.

```sh

dependencies {

    implementation 'com.chemicalbird.android:videotimelineview:0.0.4'

}

```

### Usage example

1. For fixed frame list there is already an implementation of

   `GLSurfaceView` that you can use out of the box. Your layout and code

   goes like this.

```sh

```

```sh

VideoTimeLine.with(fileUri).show(glSurfaceView);

```

2. To create a frame grabber MediaRetriever implementation use

   `RetroInstance`, for example pass it to your RecyclerView.Adapter. To

   get a frame at specific time call 

   `retroInstance.load(presentationTime, callback)`. Checkout Sample 

   project for more details.

```sh

RetroInstance retroInstance = new RetroInstance.Builder(context, mediaUri).setFrameSizeDp(180).create();

    

// in adapter

retroInstance.load(position * frameDuration, holder.hashCode(),

                file -> imageLoader.load(file, imageView));

```
