#OpenPlayer for Android

OpenPlayer is an Android library developed by AudioNow Digital, for playing audio in your mobile applications. You can use it for:

• Music
• Radio streaming

It delivers support for the following codecs:

• OPUS
• VORBIS
• MP3 - by accessing the native android library Stagefright

OpenPlayer delivers great performance, by using native codec implementation. It has been designed to decode OPUS and VORBIS content within an OGG Wrapper.

#Quick start

First of all, you need to add OpenPlayer dependency to your project. If you are using Gradle please add this modifications:

in your general build.gradle add our repository:

allprojects {
    repositories {
         ...
         maven { url "http://dl.bintray.com/audionowdigital/maven" }
    }
}

In your project build.gradle add the following dependency and sync your project.

dependencies {
    ...
    compile 'com.audionowdigital:OpenPlayer:1.0.0'
}

Using OpenPlayer to decode your media is very simple.

1 You need to create a Handler, which will receive the media events from the library

    Handler playbackHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case PlayerEvents.PLAYING_FAILED:
                    Log.d(TAG, "The decoder failed to playback the file, check logs for more details");
                    break;
                case PlayerEvents.PLAYING_FINISHED:
                    Log.d(TAG, "The decoder finished successfully");
                    break;
                case PlayerEvents.READING_HEADER:
                    Log.d(TAG, "Starting to read header");
                    break;
                case PlayerEvents.READY_TO_PLAY:
                    Log.d(TAG, "READY to play - press play :)");
                    break;
                case PlayerEvents.PLAY_UPDATE:
                    Log.d(TAG, "Playing:" + (msg.arg1 / 60) + ":" + (msg.arg1 % 60) + " (" + (msg.arg1) + "s)");
                    break;
                case PlayerEvents.TRACK_INFO:
                    Bundle data = msg.getData();
                    Log.d(TAG, "title:" + data.getString("title") + " artist:" + data.getString("artist") + " album:" + data.getString("album") +
                            " date:" + data.getString("date") + " track:" + data.getString("track"));
                    break;
            }
        }
    };

2 Create a Player instance, using the created Handler and the media type you want to decode

    Player player = new Player(playbackHandler, Player.DecoderType.OPUS);

3 Chose the content to play:

        player.setDataSource("http://www.yourserver.ro/test_file.opus", FILE_LENGTH_SECONDS);

Note: FILE_LENGTH_SECONDS is necessary for media files, for computing progress and allowing media seek. If you are decoding a live stream, you will need to use FILE_LENGTH_SECONDS = -1.

#Player Events OpenPlayer is an event-based library. The events that will be fired in the decoding process are the following:

• READING_HEADER - triggered when the library starts to read the OGG header of the stream
• TRACK_INFO - while reading the OGG Header, the library will parse track information. This event is triggered when track information is available.
• READY_TO_PLAY - called after the stream has been prepared. At this point, you can call player.play() in order to start playback
• PLAY_UPDATE - use this trigger for play progress
• PLAYING_FAILED - there has been a problem while decoding the stream.
• PLAYING_FINISHED - player reached the end of the stream

#iOS Version OpenPlayer has also been developed for iOS platform. You can find it here:
