protected final int getNextTextureImpl(final GL gl, final TextureSequence.TextureFrame nextFrame)

Implements abstract jogamp.opengl.util.av.GLMediaPlayerImpl.getNextTextureImpl.

Doc from jogamp.opengl.util.av.GLMediaPlayerImpl.getNextTextureImpl.

Process stream until the next video frame, i.e. TextureFrame, has been reached. Audio frames, i.e. AudioSink.AudioFrame, shall be handled in the process.

Video frames shall be ignored, if getVID() is STREAM_ID_NONE.

Audio frames shall be ignored, if getAID() is STREAM_ID_NONE.

Method may be invoked on the StreamWorker decoding thread.

Implementation shall care of OpenGL synchronization as required, e.g. glFinish()/glFlush()!

Parameters
gl:GL

valid and current GL instance, shall be null for audio only.

nextFrame:TextureSequence.TextureFrame

the TextureFrame to store the video PTS and texture data, shall be null for audio only.

Returns:int

the last processed video PTS value, maybe TimeFrameI#INVALID_PTS if video frame is invalid or n/a. Will be TimeFrameI#END_OF_STREAM_PTS if end of stream reached.

Implements abstract jogamp.opengl.util.av.GLMediaPlayerImpl.initGLImpl.

Doc from jogamp.opengl.util.av.GLMediaPlayerImpl.initGLImpl.

Shall initialize all GL related resources, if not audio-only.

Shall also take care of AudioSink initialization if appropriate.

Parameters
gl:GL

null for audio-only, otherwise a valid and current GL object.

Doc from jogamp.opengl.util.av.GLMediaPlayerImpl.validateTextureCount.

Returns the validated number of textures to be handled.

Default is TEXTURE_COUNT_DEFAULT minimum textures, if desiredTextureCount is < TEXTURE_COUNT_MIN, TEXTURE_COUNT_MIN is returned.

Implementation must at least return a texture count of TEXTURE_COUNT_MIN, two, the last texture and the decoding texture.

Returns GLMediaPlayer#TEXTURE_COUNT_MIN.
