If one already has the contents of a master elements in a buffer of known size, then writing a EBML master element is no different from writing an EBML binary element. It is overtly complicated to use start/end_ebml_master() as these functions first write an unkown-length size field of the appropriate length, then write the buffer's contents, followed by a seek to the length field to overwrite it with the real size (obtained via avio_tell() although it was already known in advance), followed by another seek to the previous position. Just use put_ebml_binary() instead.
