[FFmpeg-user] possible TRUN MP4 Box Version missmatch

[Sven Dueking]

Hi,

I have a question regarding the TRUN sample_composition_time_offset.
According to ISO_IEC 14496-12-2012 8.8.8.2 version 0 means this value is
unsigned int and version 1 means signed int.
But, it seems that FFMPEG interprets the other way around.
Did I miss something? 
I see something like this:
entry 0002 = sample_size:4664, sample_flags:10000,
sample_composition_time_offset:4294963696

Thanks for your help!
