Function Documentation

create_blank()

rgb_t egl::create_blank

(

platf::img_t &

img

)

Create a black RGB texture of the specified image size.

Parameters

img	The image to use for texture sizing.

Returns

The new RGB texture.

create_target()

std::optional< nv12_t > egl::create_target	(	int	width,
		int	height,
		AVPixelFormat	format )

Create biplanar YUV textures to render into.

Creates biplanar YUV textures to render into.

Parameters

width	Width of the target frame.
height	Height of the target frame.
format	Format of the target frame.

Returns

The new RGB texture.

surface_descriptor_to_egl_attribs()

std::vector< EGLAttrib > egl::surface_descriptor_to_egl_attribs

(

const surface_descriptor_t &

surface

)

Get EGL attributes for eglCreateImage() to import the provided surface.

Parameters

surface

The surface descriptor.

Returns

Vector of EGL attributes.
