• • • • • • • • • The Native Player sample application implements some of the. The sample demonstrates the media data flow: data download, the demuxing process, and displaying the content on the TV.

Data demuxer processes media content and passes the packets to the controller. DRM-protected content is decrypted (custom DRM by the Native Client.

The sample application is designed in a modular and extensible way. Its source code is released under the permissive MIT license, allowing you to reuse and customize the code to meet your own needs. You can access the latest Native Player source code from the. Important This application uses API that is now deprecated. Use raw pointers instead of shared_ptrs. Native Player Architecture The NaCl Player API is used by the NaCl module.

All player logic is implemented in the NaCl module, including user authorization, downloading and demuxing (parsing) media content, decrypting DRM-protected content, and passing demuxed elementary stream packets to the NaCl Player. The following figure shows the main structural layers, the components within the layers, and the data flow of a typical NaCl Player application: • External data for the NaCl Player application is stored in: • Media server, which stores the media content. • DRM server, which provides information needed to decrypt DRM-protected content. • Application is installed and run by the user. It consists of 2 components: • HTML5 component, which implements the UI and handles user interaction. The component has been omitted from the figure for clarity. • Native Client module component, which is responsible for the NaCl Player application logic: • Communicator handles communication with the HTML5 component, authorizing the user's access to the requested content.

• Controller interfaces with the NaCl Player by, for example, requesting data download and appending media packets to the NaCl Player. • Data provider downloads external data in chunks from the media server. • Data demuxer processes media content and passes the packets to the controller: • Downloaded content is demuxed into elementary stream packets. Clear content is not encrypted and can be parsed directly into elementary stream packets. Adobe flash professional cc 2015 crack.

• DRM-protected content is decrypted (custom DRM by the Native Client module, and platform-supported DRM by the platform). • Platform The platform contains the implementation of the player, which is responsible for performing the functions called by the application, such as decoding packets, playing audio, and rendering video on the screen. Void UrlPlayerController::InitPlayer(const std::string& url, const std::string& subtitle, const std::string& encoding) { // For external subtitles, the subtitle argument points to the location of the subtitle file // For internal subtitles, the subtitle argument must be an empty string //. Player_ = make_shared(); // Initialize listeners and register them to the player listeners_.player_listener = make_shared(message_sender_); listeners_.buffering_listener = make_shared(message_sender_); listeners_.subtitle_listener = make_shared(message_sender_); player_->SetMediaEventsListener(listeners_.player_listener); player_->SetBufferingListener(listeners_.buffering_listener); player_->SetSubtitleListener(listeners_.subtitle_listener); • Register external subtitles to the player. To check whether an external subtitle URL has been defined, and pass the address to the player. Elementary stream source playback control and data flow Data Provider To play MPEG-DASH content, the class uses the library to parse a DASH manifest file and download the appropriate media file or media chunk. The DashManifest class is also responsible for extracting Content Protection DRM initialization information included in the DASH manifest, through the class.
