Constructor Detail

EGLSurfaceTexture

public EGLSurfaceTexture(android.os.Handler handler)

Parameters:

handler - The Handler that will be used to call SurfaceTexture.updateTexImage() to update images on the SurfaceTexture. Note that init(int) has to be called on the same looper thread as the Handler's looper.

EGLSurfaceTexture

public EGLSurfaceTexture(android.os.Handler handler,
                         @Nullable
                         EGLSurfaceTexture.TextureImageListener callback)

Parameters:

handler - The Handler that will be used to call SurfaceTexture.updateTexImage() to update images on the SurfaceTexture. Note that init(int) has to be called on the same looper thread as the looper of the Handler.

callback - The EGLSurfaceTexture.TextureImageListener to be called when the texture image on SurfaceTexture has been updated. This callback will be called on the same handler thread as the handler.

Method Detail

init

public void init(@EGLSurfaceTexture.SecureMode
                 int secureMode)

Initializes required EGL parameters and creates the SurfaceTexture.

Parameters:

secureMode - The EGLSurfaceTexture.SecureMode to be used for EGL surface.

release

public void release()

Releases all allocated resources.

getSurfaceTexture

public android.graphics.SurfaceTexture getSurfaceTexture()

Returns the wrapped SurfaceTexture. This can only be called after init(int).

onFrameAvailable

public void onFrameAvailable(android.graphics.SurfaceTexture surfaceTexture)

Specified by:

onFrameAvailable in interface android.graphics.SurfaceTexture.OnFrameAvailableListener

run

public void run()

Specified by:

run in interface java.lang.Runnable
