/**
* GLMediaPlayer interface specifies a {@link TextureSequence} state machine
* using a multiplexed audio/video stream as it's source.
*
* Audio maybe supported and played back internally or via an {@link AudioSink} implementation.
*
*
* Audio and video streams can be selected or muted via {@link #initStream(Uri, int, int, int)}
* using the appropriate stream id's.
*
*
* Camera input can be selected using the {@link #CameraInputScheme} Uri.
*
*
* StreamWorker Decoding Thread
*
* Most of the stream processing is performed on the decoding thread, a.k.a. StreamWorker:
*
* - Stream initialization triggered by {@link #initStream(Uri, int, int, int) initStream(..)} - User gets notified whether the stream has been initialized or not via {@link GLMediaEventListener#attributesChanged(GLMediaPlayer, int, long) attributesChanges(..)}.
* - Stream decoding - User gets notified of a new frame via {@link GLMediaEventListener#newFrameAvailable(GLMediaPlayer, com.jogamp.opengl.util.texture.TextureSequence.TextureFrame, long) newFrameAvailable(...)}.
* - Caught exceptions on the decoding thread are delivered as {@link StreamException}s.
*
* StreamWorker generates it's own {@link GLContext}, shared with the one passed to {@link #initGL(GL)}.
* The shared {@link GLContext} allows the decoding thread to push the video frame data directly into
* the designated {@link TextureFrame}, later returned via {@link #getNextTexture(GL)} and used by the user.
*
* StreamWorker Error Handling
*
* Caught exceptions on StreamWorker are delivered as {@link StreamException}s,
* which either degrades the {@link State} to {@link State#Uninitialized} or {@link State#Paused}.
*
*
* An occurring {@link StreamException} triggers a {@link GLMediaEventListener#EVENT_CHANGE_ERR EVENT_CHANGE_ERR} event,
* which can be listened to via {@link GLMediaEventListener#attributesChanged(GLMediaPlayer, int, long)}.
*
*
* An occurred {@link StreamException} can be read via {@link #getStreamException()}.

* Audio and video Stream IDs
*
*
* value request get {@link #STREAM_ID_NONE} mute not available {@link #STREAM_ID_AUTO} auto unspecified ≥0 specific stream specific stream
*
*
* Current implementations (check each API doc link for details):
*
* - {@link jogamp.opengl.util.av.NullGLMediaPlayer}
* - {@link jogamp.opengl.util.av.impl.OMXGLMediaPlayer}
* - {@link jogamp.opengl.util.av.impl.FFMPEGMediaPlayer}
* - {@link jogamp.opengl.android.av.AndroidGLMediaPlayerAPI14}
*
*
*
* Implementations of this interface must implement:
*
* public static final boolean isAvailable();
*
* to be properly considered by {@link GLMediaPlayerFactory#create(ClassLoader, String)}
* and {@link GLMediaPlayerFactory#createDefault()}.
*
* Timestamp Accuracy
*
*
* Timestamp type and value range has been chosen to suit embedded CPUs
* and characteristics of audio and video streaming. See {@link TimeFrameI}.
*
*
* Audio and video synchronization
*
* The class follows a passive A/V synchronization pattern.
* Audio is being untouched, while {@link #getNextTexture(GL)} delivers a new video frame
* only, if its timestamp is less than {@link #MAXIMUM_VIDEO_ASYNC} ahead of time.
* If its timestamp is more than {@link #MAXIMUM_VIDEO_ASYNC} ahead of time,
* the previous frame is returned.
* If its timestamp is more than {@link #MAXIMUM_VIDEO_ASYNC} after time,
* the frame is dropped and the next frame is being fetched.

*
*
* Recommendation of audio/video pts time lead/lag at production:
*
* - Overall: +40ms and -60ms audio ahead video / audio after video
* - Each stage: +5ms and -15ms. audio ahead video / audio after video
*
*
*
* Recommendation of av pts time lead/lag at presentation:
*
* - TV: +15ms and -45ms. audio ahead video / audio after video.
* - Film: +22ms and -22ms. audio ahead video / audio after video.
