HLS Server not working with apple device

[Olivier Crête]

Hello,

One problem you may be having is that neither rtph264depay nor
h264parse insert the NAL unit type 9 (AU delimiter) between the AUs in
the H.264 Elementary Stream. This is required to make a valid MPEG-TS
stream, but most decoders will be fined even if it is missing, but it
seems Apple's decoders are more pedantic. In RTP streams, the AUD nal
is entirely useless, as the same information is expressed by the marker
bit, so they are normally not included.

See bug:
