https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming#section-3.4 A Packed Audio Segment has no Media Initialization Section.
Each Packed Audio Segment MUST signal the timestamp of its first sample with an ID3 PRIV tag [ID3] at the beginning of the segment. The ID3 PRIV owner identifier MUST be "com.apple.streaming.transportStreamTimestamp". The ID3 payload MUST be a 33-bit MPEG-2 Program Elementary Stream timestamp expressed as a big-endian eight-octet number, with the upper 31 bits set to zero. Clients SHOULD NOT play Packed Audio Segments without this ID3 tag.
mp3 options: -write_xing 0/1 -id3v2_version 3 -write_id3v1 0/1
