◆ CreateBuffer()

bool MythVideoTextureOpenGL::CreateBuffer	(	MythVideoTextureOpenGL *	Texture,
		int	Size
	)

inlinestaticprivate

Create a data buffer for holding CPU side texture data.

		VideoFrameType	Type,
		VideoFrameType	Format,
		std::vector< QSize >	Sizes,
		GLenum	Target
	)

staticprivate

Create a set of hardware textures suitable for the given format.

Note: This is a simple wrapper that deliberately does nothing more than create a texture and sets suitable defaults. In most instances, hardware textures require specific handling.; Linear filtering is always set (except MediaCodec/MMAL which use OES)

		VideoFrameType	Type,
		VideoFrameType	Format,

		GLenum	Target
	)

staticprivate

Create a set of OpenGL textures to represent the given Format.

Note: All textures are created with CreateTexture which defaults to Linear filtering.

		QOpenGLTexture::Filter	Filter = `QOpenGLTexture::Linear`,
		QOpenGLTexture::WrapMode	Wrap = `QOpenGLTexture::ClampToEdge`
	)

static

Create and initialise a MythVideoTexture that is backed by a QOpenGLTexture.

QOpenGLTexture abstracts much of the detail of handling textures but is not compatible with a number of hardware decoder requirements.
