There was a quick solution at aa25198f1b925a464bdfa83a98476f08d26c9209,
which luckily works for #7572. To reproduce issue, you can switch to the
commit just before it.

As we discussed, #7572 has a deeper reason. We missed the last ‘sidx’ and
‘moof’ boxes.

This patch try to fix AV_NOPTS_VALUE in fragmented info structure. It may
be caused by missing boxes. Or the fragmented structures are not suitable
for separate audio and video ‘moof’.

Thanks and Regards,

Charles Liu
