Copies gl_mem into the texture specified by tex_id. The format of tex_id is specified by tex_format, width and height.
Copies the texture in #GstGLMemory into the texture specified by tex_id, out_target, out_tex_format, out_width and out_height.
Initializes mem with the required parameters. info is assumed to have already have been modified with gstvideo.video_info.VideoInfo.align_.
Reads the texture in #GstGLMemory into write_pointer if no buffer is bound to GL_PIXEL_PACK_BUFFER. Otherwise write_pointer is the byte offset into the currently bound GL_PIXEL_PACK_BUFFER buffer to store the result of glReadPixels. See the OpenGL specification for glReadPixels for more details.
Reads the texture in read_pointer into gl_mem.
Initializes the GL Base Texture allocator. It is safe to call this function multiple times. This must be called before any other GstGLMemory operation.
Pointer to the C boxed value
Get the GType of this boxed type.
Boxed GType property.
Convenience method to return this cast to a type. For use in D with statements.
Make a copy of the wrapped C boxed data.
Copy a C boxed value using g_boxed_copy.
Free a C boxed value using g_boxed_free.
GstGLMemory is a #GstGLBaseMemory subclass providing support for the mapping of OpenGL textures.
#GstGLMemory is created or wrapped through gstgl.glbase_memory.GLBaseMemory.alloc with #GstGLVideoAllocationParams.
Data is uploaded or downloaded from the GPU as is necessary.
The #GstCaps that is used for #GstGLMemory based buffers should contain the GST_CAPS_FEATURE_MEMORY_GL_MEMORY as a #GstCapsFeatures and should contain a 'texture-target' field with one of the #GstGLTextureTarget values as a string, i.e. some combination of 'texture-target=(string){2D, rectangle, external-oes}'.
