ANDROID IMEDIA PLAYER
If you're someone that has smart speakers located in different areas of your home or office, chances are, you've been in a situation where you've moved around the space, and the audio needs to be toggled to different speakers in order to continue enjoying your tunes. For the most part, you'll be doing this through your phone or maybe a tablet, and sometimes it can become tedious, especially if you need to open up the app to make these changes. Android has media output controls, giving users the option to select a device and stream music to it. The output controls even got a slight revamp with the refreshed media player built into Android 13.
If you're a Spotify user, what you might have noticed missing from the new Android media player is that despite most features being present, there isn't the ability to toggle audio through Spotify Connect devices. Spotify Connect devices use different technology and offer benefits such as increased battery life of the connected device, higher quality playback, seamless playback when switching devices, and more. While this can currently be done from the Spotify app, being able to switch devices from the built-in Android media player will make things even more convenient, with easy access from the notification panel and lock screen.
MediaMonkey is an excellent music player with video playing capabilities. Most of its features are music-focused. However, you can absolutely watch video content with it. Additionally, MediaMonkey has a desktop variant for PC that also lets you view music and video content and sync content between your computer and phone. It supports most music and video formats along with some extras like audiobooks and podcasts. The app also has a widget, Android Auto support, Chromecast support, a sleep timer, and some other features. This one is quite good if you want a full-featured music player with video player capabilities.

In this article, I present the architecture of the media playback infrastructure (with Stagefright as the underlying media player). My goal is to help you, an interested reader, get a grasp of how things work behind the curtains, and to help you more easily identify the part of the code base you may want to tweak or optimize. Some useful online resources already outline certain bits and pieces of the media player architecture (1 2), but the slideshow format of these descriptions omits a number of important details.
The architecture of the media player infrastructure, from the end-user apps to the media codecs that perform the algorithmic magic, is layered with many levels of indirection. The following diagram depicts the high-level architecture described below.
At the topmost layer of the architecture are the user apps that leverage media playback functionality, such as playing audio streams, ringtones, or video clips. These apps use the components from the Application Framework that implement the high-level interfaces for accessing and manipulating media content. Below this layer, things get more complicated as the Application Framework components communicate with native C++ components through JNI interfaces. These native components are essentially thin clients that forward media requests from Java code to the underlying Media Player Service via IPC calls. The Media Player Service selects the appropriate media player (in our case Stagefright), which then instantiates an appropriate media decoder, as well as fetches and manipulates the media files, manages buffers, etc. While even this high-level architecture is relatively complex, the devil is still in the details, so I will now guide you through the different subsystems.
Once a playback request goes through the JNI interface, the control flow and dataflow of the requests become more difficult to track inside the source code due to a lack of documentation and the intricate invocation mechanisms. The JNI interface connects the Application Framework with C++ implementations of some methods located in the folder frameworks/base/media/jni. The most frequently invoked native methods are located in android_media_MediaPlayer.cpp file, which instantiates a C++ MediaPlayer object for each new media file and routes requests from the Java MediaPlayer objects to their C++ counterparts. The implementations of these C++ classes are located under frameworks/av/media, while their interface definitions can be found in frameworks/av/include/media. If you expect that these classes implement the actual media playback functionalities, you will be disappointed to hear they are only adding yet another level of indirection, serving as thin IPC clients to the underlying lower-level media services. For example, MediaPlayer::start() does nothing more than route invocations to the IMediaPlayer interface, which then performs an IPC invocation transact(START, data, &reply) to start the playback.
The IPC requests from the Native Media Player Subsystem are in turn handled by the Media Player Service subsystem (the subsystem mostly comprises C++ classes in the frameworks/av/media/libmediaplayerservice folder). This subsystem is initialized in the main() method of frameworks/av/media/mediaserver/main_mediaserver.cpp, which includes startup of multiple Android servers such as AudioFlinger, MediaPlayerService (relevant for our discussions), and CameraService. The instantiation of the Media Player Service subsystem involves creation of a MediaPlayerService object, as well as instantiation and registration of factories for the built-in media player implementations (NuPlayer, Stagefright, Sonivox). Once up and running, MediaPlayerService will accept IPC requests from the Native Media Player subsystem and instantiate a new MediaPlayerService::Client for each request that manipulates media content. To play the media, Client has a method createPlayer that creates a low-level media player of a specified type (in our case StagefrightPlayer) using the appropriate factory. The subsequent media playback requests (e.g., pausing, resuming, and stopping) are then directly forwarded to the new instance of StagefrightPlayer.
StagefrightPlayer class is a thin client to the actual media player named AwesomePlayer. The Stagefright Media Player subsystem, located in the folder frameworks/av/media/libstagefright, implements the algorithmic logic (unsurprisingly, many of the files have sizes in the range of thousands of SLOC). The detailed architecture of this subsystem is depicted in the following figure.
While this article qualifies as a fairly lengthy blog post, I only scratched the surface of the complex media playback functionality. Thus, if you find something unclear or would like to discuss the architecture further, please do not hesitate to comment or contact us directly. Also, I would like to invite you to read a separate article that provides a set of tips & tricks for manually recovering a software architecture that uses the media player as an example.
A new media player is in town: robust (metallic case), dual band WiFi, 4K, supports screen rotation and 2 videos in parallel. What more can I ask? This is a robust RK3288 by Screens TV, a digital signage all-in-one company.
Part of the motivation for media controls is that users often have multiple media apps (music player, podcasts, video player etc) and regularly switch between them. Media controls display up to five current and recent media sessions in a carousel allowing the user to swipe between them.
The A400 is the first, and currently the best 4K Android solution in 2017 for app support combined with strong local file playback capability. It provides support for most of the latest video file formats. The A400's chipset is the very latest in technology and provides unprecedented levels of performance. It is totally different from almost all other Android media players.
