Checks to see if a GLES error has been raised.

Discards all resources held by this class, notably the EGL activity. This must be called from the thread where the activity was created. <p> On compl

Creates a new program from the supplied vertex and fragment shaders. @return A handle to the program, or 0 on failure.

Checks to see if the location we obtained is valid. GLES returns -1 if a label could not be found, but does not set the GL error. <p> Throws a Runtim

Allocates a direct float buffer, and populates it with the float array data.

Read a string from an AMF encoded buffer. @param data The buffer from which to read. @return The value read from the buffer.

Sets the display orientation of the camera for portrait or landscape orientation

Returns a new DataSource factory. @param useBandwidthMeter Whether to set {@link #BANDWIDTH_METER} as a listener to the new DataSource factory. @

Checks for EGL errors. Throws an exception if an error has been raised.

Consumes payload data. @param data The payload data to consume. @param timeUs The timestamp associated with the payload. @throws ParserException If a

Creates an EGL surface associated with a Surface. <p> If this is destined for MediaCodec, the EGLConfig should have the "recordable" attribute.

Extracts all pending data from the encoder and forwards it to the muxer. <p> If endOfStream is not set, this returns when there is no more data to dra

Draws a viewport-filling rect, texturing it with the specified texture object.

Finds a suitable EGLConfig. @param flags Bit flags from constructor. @param version Must be 2 or 3.

@return current preview size of the active camera

Returns the surface's width, in pixels. <p> If this is called on a window surface, and the underlying surface is in the process of changing size, we m

Handles a request to stop encoding.

Returns true if recording has been started.

Compiles the provided shader source. @return A handle to the shader, or 0 on failure.

Makes our EGL activity current, using the supplied surface for both "draw" and "read".

Notifies the renderer thread that the activity is pausing. <p> For best results, call this after disabling Camera preview.

Opens camera in an another thread and render camera view on GLSurfaceView @param cameraId specifies which camera to open can be

Performs a simple surface query.

Read a double number from an AMF encoded buffer. @param data The buffer from which to read. @return The value read from the buffer.

Read an ECMA array from an AMF encoded buffer. @param data The buffer from which to read. @return The value read from the buffer.

Release the EGL surface.

Records the size of the incoming camera preview frames. <p> It's not clear whether this is guaranteed to execute before or after onSurfaceCreated(), s

Set the resolution of the active camera @param size

Sets the size of the texture. This is used to find adjacent texels when filtering.

Tells the video recorder to start recording. (Call from non-encoder thread.) <p> Creates a new thread, which will create an encoder using the provide

Tells the video recorder to stop recording. (Call from non-encoder thread.) <p> Returns immediately; the encoder/muxer may not yet be finished creati

Returns a new HttpDataSource factory. @param useBandwidthMeter Whether to set {@link #BANDWIDTH_METER} as a listener to the new DataSource factor

Changes the camera, if active camera is back camera, releases the back camera and open the front camera, it behaves same with the front camera

Creates a texture object suitable for use with drawFrame().

Issues the draw call. Does the full setup on every call. @param mvpMatrix The 4x4 projection matrix. @param vertexBuffer Buffer with vertex position

Tells the video recorder that a new frame is available. (Call from non-encoder thread.) <p> This function sends a message and returns immediately. T
