[Openquicktime-devel] Fix for larger than 4GB file output

[Jean-Francois P. <pan...@co...>]

Currently, the mdat atom at the head of a QuickTime file generated by 
oqt has a 32 bit size field,
limiting the file size to 4GB. By default, Apple QuickTime uses a 64 bit 
mdat atom in case the
file grows larger than 4GB: this only adds 8 bytes to a file and is 
probably what you want to do.
Here's a patch for lib/openquicktime.c which does this and seems to work 
(there was already support
for 64 bit atoms in the code, but it didn't seem to be used).
