Parsing of large files (> 2Gb) fail due to long to int conversions

[GoogleCodeExporter]

First: tank you for this contribution.

May I suggest avoiding long to int conversions, it blocks access to files 
larger than 2Gb.

i.e. in
- com.coremedia.iso.BoxFactory.parseBox()
- com.coremedia.iso.IsoInputStream.skip()

Best regards

I'll try to fix it in the next days. Thank you for your for reporting this bug. 
I really never tried file of this size.

I think the problem is gone. Can anyone point me to a really big MP4 file?

Thanks, 
Here is a 2.6Gb file:

Ok, 1h to go! 2,6GB is really a lot for my connection.

The boxes in that 2,6GB file can now be parsed without any problems on 64Bit 
systems. It seems need memory mapped files need equal room in the address-space 
as in filesystem so there might be problems getting that much continuous memory 
from a 32 Bit OS. 
There are still difficulties parsing chunks and samples since they are just too 
many to have an object representation each.

Thanks a lot, 

For information, in my case, I was only interested in getting and parsing Movie 
Header Box (mvhd) to extract meta data such as duration.

The fact that the full parsing a such large file can be very long and difficult 
does not hurt me.
