Hi
i'm writing my first qt/cpp app and i'm confused,
My app use third library from Hikvision SDK playctrl.
it work nice on my Mageia 8 PC, but on my Raspberry P400 Linux raspberrypi 5.15.30-v8+ #1535 SMP PREEMPT Wed Mar 23 16:40:19 GMT 2022 aarch64 GNU/Linux, it randomly crash with the error in the title of here.

I cannot find if it come from my code, compilation on the pi, sdk or qt itself

my prog is here :
https://github.com/surfzoid/QtVsPlayer

to be sure, i can provide an h265 video sample with motion in metadata.
The crash happen when reading video at 6x speed, sometime after second file from playlist, sometime 7, 8 and so on.

i thank you to take time to read me
