3gp file with issue

it seem that one stts_data give an invalid duration (maybe) due to file corruption:
qtdemux qtdemux.c:3605:qtdemux_parse_samples:<demux> block 3, 1 timestamps, duration 4294917294 

Can we detect this kind of invalid duration and maybe replace it by the min_duration ?

patch draft

I have made the same test with the latest delivery of qtdemux done by Tim-Philipp Müller, the issue still occur and the correction seem to be the same.
I'm not very sure that testing duration > 0xFFFF0000 while not generate regression on other streams.

    qtdemux: add durations modulo 1<<32
    
    For calculating the durations of each sample, we are supposed to add each
    duration modulo 1<<32 so make the elapsed time counter a uint32.
    
    Fixes #595942
