Play Video File using LibVLC on Android

VLC engine on Android application can be embedded using LibVLC library. This tutorial provides example how to play a video file using LibVLC on Android application.

Firstly, add the LibVLC library as dependency in the module's build.gradle file.

app/build.gradle

dependencies {
    // Other dependencies
    // ...
    implementation 'org.videolan.android:libvlc-all:3.4.4'
}

To display video, we should add a VLCVideoLayout in the layout XML file. Also add the button for opening a file browser.

app/src/main/res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/openButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:text="Open" />

    <org.videolan.libvlc.util.VLCVideoLayout
        android:id="@+id/videoLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

Make sure you have a video file in your mobile device. For example, you can download the following video for testing:

We attached the click listener to open a file browser when button is clicked. When the user selected a video file, the playVideo method is called. It opens a file with the read mode. After that, an instance of the Media class is created and video begin to play.

When the activity is stopped, the media player is stopped too and video layout is detached from player. When the activity is destroyed, resources is released.
