PlugInManager -maintains a registry of available JMF plug-in processing components, such as Multiplexers, Demultiplexers, Codecs, Effects, and Renderers. CaptureDeviceManager -maintains a registry of available capture devices. PackageManager -maintains a registry of packages that contain JMF classes, such as custom Players, Processors, DataSources, and DataSinks. This level of indirection allows new implementations to be integrated seamlessly with JMF. Managers JMF uses four managers: Manager -handles the construction of Players, Processors, DataSources, and DataSinks. Push data-sources include broadcast media, multicast media, and video-on-demand (VOD). Push Data-Source -the server initiates the data transfer and controls the flow of data from a push data-source. JMF data sources can be categorized according to how data transfer is initiated: Pull Data-Source -the client initiates the data transfer and controls the flow of data from pull data-sources. A buffer data source uses a Buffer object as its unit of transfer.
( Note : In Java, a URL can only be constructed if the corresponding protocol handler is installed on the system.) A standard data source uses a byte array as the unit of transfer. A MediaLocator is similar to a URL and can be constructed from a URL, but can be constructed even if the corresponding protocol handler is not installed on the system. A DataSource is identified by either a JMF MediaLocator or a URL (universal resource locator). Once obtained, the source cannot be reused to deliver other media.

A DataSource encapsulates both the location of media and the protocol and software used to deliver the media. JMF Architecture,its Interfaces & its classesĭata Model JMF media players usually use DataSources to manage the transfer of media-content.

Feel free to drop any type of audio media files but dont forget to change the reference of the files in the Audio Activity.Īlways release the media instance back to system in this i.e. In the res folder, created a raw folder to keep the raw media files in this case robotrack.mp3 (called by R.raw.robotrack)and other types of raw media files. The onPause() method is overrided to give playerback control to this instance. When the audiodemo starts note the change of the button change from "Play" to "Stop" and when the demo is paused a return of button text to "Play" Added a toast message to notify the user what is going on. The AudioDemo is straight forward creating the layout and listening to the button click events and response accordingly. Use of the various player instance methods like ay() or player.pause() to do as they suggest to play and pause the media playback. Most importantly is the creation of the media player instance MediaPlayer player = MediaPlayer.create(ntext, media source). In this demo, we work with the audio media player API to play a raw media file and can also be used for streaming media.
