mp4 atom too large

[Richard Kearsley]

Hi

I use ngx_http_mp4_module quite heavily, and very occasionally I see 
this error for a few files:

mp4 atom too large:723640794

With the number differing.. Is the number the size of the atom in bytes?
If so, 723640794 is around 690MB and the mp4 file is only around 150MB

The same file works with the "other" mp4 module

What can we do to find the problem?

Many thanks
