 Hello when using the latest version (4.4) of ffmpeg on linux, I run into a
 strange issue when converting mp4 to hls with fmp4 segment.

 the init.mp4 file doesn't not contain the headers info. but rather the
 first segment and the first segment empty.

 How to reproduce:
 {{{
 % ffmpeg -i /test/video.mp4 -c copy -hls_time 10 -hls_playlist_type vod
 -hls_segment_type fmp4 -tune zerolatency -hl -hls_segment_type fmp4 -tune
 zerolatency -hls_fmp4_init_filename init.mp4 /test/org.m3u8
 }}}

 On version 4.3.1 and below this work as expected and doesn't seem to be an
 issuse.

 but on 4.4 I is where I run it to this issue, build I tested that has this
 issue:
 https://pkgs.alpinelinux.org/package/edge/community/x86_64/ffmpeg
 And
 https://hub.docker.com/r/jrottenberg/ffmpeg/
 (jrottenberg/ffmpeg:4.4-alpine)


 Thank you.
