Implementation according to RFC 4587. Payloader create fragments on MB boundaries in order to match MTU size the best it can. Some decoders/depayloaders in the wild are very strict about receiving a continuous bit-stream (e.g. no no-op bits between frames), so the payloader will shift the compressed bit-stream of a frame to align with the last significant bit of the previous frame. Depayloader does not try to be fancy in case of packet loss. It simply drops all packets for a frame if there is a loss, keeping it simple. https://bugzilla.gnome.org/show_bug.cgi?id=751886
