io.cine.android.streaming.CameraSurfaceRenderer

All Implemented Interfaces:

public class CameraSurfaceRenderer
extends java.lang.Object
implements android.opengl.GLSurfaceView.Renderer

Renderer object for our GLSurfaceView.

Do not call any methods here directly from another thread -- use the GLSurfaceView#queueEvent() call.

Constructor Detail

CameraSurfaceRenderer

public CameraSurfaceRenderer(BroadcastActivity.CameraHandler cameraHandler,
                     TextureMovieEncoder movieEncoder,
                     Muxer muxer)

Constructs CameraSurfaceRenderer.

Parameters:

cameraHandler - Handler for communicating with UI thread

movieEncoder - video encoder object

muxer - output file for encoded video; forwarded to movieEncoder

Method Detail

notifyPausing

public void notifyPausing()

Notifies the renderer thread that the activity is pausing.

For best results, call this *after* disabling Camera preview.

changeRecordingState

public void changeRecordingState(boolean isRecording)

Notifies the renderer that we want to stop or start recording.

setCameraPreviewSize

public void setCameraPreviewSize(int width,
                        int height)

Records the size of the incoming camera preview frames.

It's not clear whether this is guaranteed to execute before or after onSurfaceCreated(), so we assume it could go either way. (Fortunately they both run on the same thread, so we at least know that they won't execute concurrently.)

onSurfaceCreated

public void onSurfaceCreated(javax.microedition.khronos.opengles.GL10 unused,
                    javax.microedition.khronos.egl.EGLConfig config)

Specified by:

onSurfaceCreated in interface android.opengl.GLSurfaceView.Renderer

onSurfaceChanged

public void onSurfaceChanged(javax.microedition.khronos.opengles.GL10 unused,
                    int width,
                    int height)

Specified by:

onSurfaceChanged in interface android.opengl.GLSurfaceView.Renderer

onDrawFrame

public void onDrawFrame(javax.microedition.khronos.opengles.GL10 unused)

Specified by:

onDrawFrame in interface android.opengl.GLSurfaceView.Renderer
