B4A Library ExoPlayer - MediaPlayer / VideoView Alternative

Erel · Nov 3, 2016

Edit: new version: https://www.b4x.com/android/forum/threads/exoplayer-media3-video-player.158204/

ExoPlayer is an open source project that replaces the native MediaPlayer and VideoView types.
https://google.github.io/ExoPlayer/
License: Apache 2.0

It supports more media formats, it is more powerful and more customizable.
It is supported by Android 4.1+ (API 16+).

There are two types: SimpleExoPlayer and SimpleExoPlayerView.

SimpleExoPlayer is the internal engine, it is similar to MediaPlayer. SimpleExoPlayerView provides the interface.
SimpleExoPlayer can be used without the interface.
SimpleExoPlayer should be a process global variable.

Example of video playback from an asset file (same exact code will work with audio files as well):

B4X:

Sub Process_Globals
   Private player1 As SimpleExoPlayer
End Sub

Sub Globals
   Private SimpleExoPlayerView1 As SimpleExoPlayerView
End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     player1.Initialize("player")
     player1.Prepare(player1.CreateFileSource(File.DirAssets, "BLE_Chat.mp4"))
   End If
   Activity.LoadLayout("1")
   SimpleExoPlayerView1.Player = player1 'Connect the interface to the engine
End Sub

You can use player.CreateUriSource to load a remote resource:

B4X:

player1.Prepare(player1.CreateUriSource("https://..."))

Or you can use one of the following methods for streaming resources:

CreateHLSSource - Http Live Streaming
CreateDashSource - Dynamic Adaptive Streaming over Http
CreateSmoothStreamingSource - Smooth Streaming

You can also create a playlist with multiple sources:

B4X:

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     player1.Initialize("player")
     Dim sources As List
     sources.Initialize
     sources.Add(player1.CreateDashSource("http://www.youtube.com/api/manifest/dash/id/bf5bb2419360daf1/source/youtube?as=fmp4_audio_clear,fmp4_sd_hd_clear&sparams=ip,ipbits,expire,source,id,as&ip=0.0.0.0&ipbits=0&expire=19000000000&signature=51AF5F39AB0CEC3E5497CD9C900EBFEAECCCB5C7.8506521BFC350652163895D4C26DEE124209AA9E&key=ik0"))
     sources.Add(player1.CreateHLSSource("https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8"))
     sources.Add(player1.CreateUriSource("http://html5demos.com/assets/dizzy.mp4"))
     player1.Prepare(player1.CreateListSource(sources))

   End If
   Activity.LoadLayout("1")
   SimpleExoPlayerView1.Player = player1
   player1.Play
End Sub

The library is attached.

It depends on several additional aar files (should be copied to the additional libraries folder):
www.b4x.com/android/files/exoplayer-additional_libs.zip

Updates:

V1.52 - Previous fix was incomplete. New version solves the issue.
V1.51 - Fixes an incompatibility between ExoPlayer and Firebase. Make sure to update the additional libs package.
V1.50 - New version based on ExoPlayer 2.13.3 (https://github.com/google/ExoPlayer/blob/release-v2/RELEASENOTES.md). The additional libs package was also updated.
V1.41 - Fixes a bug where the designer properties where missing.
V1.40 - Based on ExoPlayer v2.11.3. Make sure to update the additional libs as well.

V1.30 - New InitializeCustom method that allows creating the native player with JavaObject.

V1.20 - Based on ExoPlayer v2.10.2. This is a large update. Not all existing customizations (based on JavaObject) will work without modifications.

V1.10 - Based on ExoPlayer v2.5.3.

Make sure to update the additional aar files as well.

Can you post a screenshot of your Android SDK Manager?

1. Are you sure that the IDE is configured to use this SDK (under Tools - Configure Paths)?
2. Try to delete build tools 23.0.1 and 23.0.3.

yes it is configured corectly and i have one more error with http, okhttp ,httputils2 and okhttputils

DonManfred · Nov 27, 2016

Which android.jar did you specify in the IDE -> Configure Paths?
It should be from platform 23 or 24

Based on
https://developer.android.com/refer...ce.html#onTaskRemoved(android.content.Intent)
it should be api 14 or higher.

I suggest to use the most up-to-date android.jar

Replace the old http and httputils with okHTTP and okhttputils2
