Why don't you want to use RTP payloaders?

A solution without would be to ensure that no NAL is bigger than 64k
(you ideally want no bigger than 1500 bytes!), by changing the encoder
settings accordingly and having h264parse really put one NAL per
buffer. alignment=nal only means that it's one or more NALs.
