20 * @brief This is the header file for the %VideoTexture class.
22 * This header file contains the declarations of the %VideoTexture class.

34 class IVideoTextureUpdateListener;
38 * @brief This class provides a method to bind a video frame to OpenGL-ES Texture.
39 * With this feature, you can easily draw a video frame on OpenGL-ES Textures with consistency.
43 * @final This class is not intended for extension.
45 * The %VideoTexture class provides a texture by which you can draw a video frame on OpenGL-ES texture.
48 class _OSP_EXPORT_ VideoTexture
49 : public Tizen::Base::Object
53 * The object is not fully constructed after this constructor is called. For full construction, the Construct() method be called right after calling this constructor.
61 * This destructor overrides Tizen::Base::Object::~Object().
65 virtual ~VideoTexture(void);
68 * Initializes this instance of %VideoTexture with the specified parameters.
71 * @feature %http://tizen.org/feature/opengles, %http://tizen.org/feature/opengles.version.1_1, or %http://tizen.org/feature/opengles.version.2_0
73 * @return An error code
74 * @param[in] textureId Texture ID which points to the texture associated with the video frame @n The texture ID must be generated from glGenTextures().
75 * @param[in] width The width of the input texture. The width must be greater than @c 32, and smaller or equal than GL_MAX_TEXTURE_SIZE.
76 * @param[in] height The height of the input texture. The height must be greater than @c 32, and smaller or equal than GL_MAX_TEXTURE_SIZE
77 * @exception E_SUCCESS Construction is successfully done.
78 * @exception E_OUT_OF_RANGE The width or height is bigger than GL_MAX_TEXTURE_SIZE You can get max size of current device to call glGetIntegerv(GL_MAX_TEXTURE_SIZE, &maxSize).
79 * @exception E_INVALID_ARG A specified input parameter is invalid.
80 * @exception E_UNSUPPORTED_OPERATION The Emulator or target device does not support the required feature.
81 * For more information, see <a href="../org.tizen.gettingstarted/html/tizen_overview/application_filtering.htm">Application Filtering</a>.
82 * @exception E_INVALID_STATE Getting egl information failed. It is necessary to bind egl context by using eglMakeCurrent() method.
84 * - Before calling this method, check whether the feature is supported by Tizen::System::SystemInfo::GetValue(const Tizen::Base::String&, bool&).
85 * - There is a high probability for an occurrence of an out-of-memory exception. If possible, check whether the exception is @c E_OUT_OF_MEMORY or not. For more information on how to handle the out-of-memory exception, refer <a href="../org.tizen.native.appprogramming/html/basics_tizen_programming/exception_check.htm">here</a>.
