@Generated("org.javagi.JavaGI") public class VideoGLTextureUploadMeta extends ProxyInstance
Extra buffer metadata for uploading a buffer to an OpenGL texture ID. The caller of gst_video_gl_texture_upload_meta_upload() must have OpenGL set up and call this from a thread where it is valid to upload something to an OpenGL texture.
