As I understand, the PPS/SPS are changing due to segment change and
split encoding.

This might happen with all adaptive streaming protocols then.

I'm unsure why we need it as fmt_out codec extra and not in the stream.

If the codec fails to handle new pps/sps, that should be done at decoder
level, no ? (if packetizer is missing, that fix will fail).

Decoding will fail if two segments have same sps/pps size sum but
different sps/pps.
