 In the player, it plays stream video + audio. It works on all platform
 except iOS mobile (safari). It just plays one segment of the live video +
 sound and then the audio is off. But when I turn OFF/ON sound in the
 player it became works but again only one segment. Tried with clappr and
 plyr players.

 The main point why I'm asking here is that it works properly when I use
 `ts` files, ie:

 {{{
 ffmpeg -use_wallclock_as_timestamps 1
        -loglevel warning
        -fflags nobuffer
        -rtsp_transport tcp
        -i rtsp://127.0.0.1:10270/proxyStream
        -c:v copy
        -c:a aac -b:a 64k -ac:a 2 -ar 44100 -af aresample=async=1000
        -g 48
        -keyint_min 48
        -sc_threshold 0
        -use_localtime 1
        -hls_time 2
        -hls_list_size 2
        -hls_flags delete_segments+append_list
        -hls_base_url '/api/v1/cameras/5d7f91b5a34dbe6f53a78a6a/live?file='
        -hls_segment_filename 5d7f91b5a34dbe6f53a78a6a-%s.ts
        5d7f91b5a34dbe6f53a78a6a.m3u8
 }}}

 Any Ideas why it happens? Thanks
