accumulation of 8-bits uint_8 (uint8_t *src) into 32-bits (uint32_t *ii)
data type, it will have a risk of an integral value becoming larger than
the 32-bits integer capacity and resulting in an integer overflow. For
this risk, add a checking with warning message.

Thanks for your reply.
If a track id of the test clip does not appear in its ‘moov’, the do/while
loop cannot exit indeed.
The purpose of this patch is to solve AV_NOPTS_VALUE in the fragment info
structure. Because the original structures is oriented to ‘moof’ boxes in
file. I tried to organize
1. organize fragmented information according to the tracks.
2. do NOT skip the last boxes of fragmented info.
