Hi,
Everything is in the title.
I only have this issue with the option -dynamic of MP4Box.

Steps to reproduce:

Gpac is compiled from master.
Here is the 10 seconds stream BigBuckBunny_10s.hevc.

mkdir -p /tmp/gpac/tmpmp4box
mkdir -p /tmp/gpac/out

gpac/bin/gcc/MP4Box -tmp /tmp/gpac/tmpmp4box -add ~/BigBuckBunny_10s.hevc:xps_inband:trailing -new /tmp/gpac/main.mp4

gpac/bin/gcc/MP4Box -dash 2000 -dynamic -mpd-refresh 1 -profile simple -bound -segment-name "" -out /tmp/gpac/out/main.mpd -tmp /tmp/gpac/tmpmp4box /tmp/gpac/main.mp4

Output:

$ ls /tmp/gpac/out
5.m4s  init.mp4  main.mpd

[1-4].m4s files are missing whereas they were present in v0.8.0.
