Modify the decoder to return the ending position of the bool decoder and use that as the starting position for the next frame. The constant-space algorithm for parsing the appended frame lengths is O(n^2), which is a potential DoS concern if n is unbounded. Revisit the appended lengths for use as partition lengths when multipartition support is added. In addition, this allows decoding of raw streams outside of a container without additional framing information, though it's insufficient to be able to remux said stream into a container.
