Genisoimage can't make ISO with file >4G

kotnik · 09-03-2007, 04:43 AM

I have a 4.4G file. And this is what happens when I try to make an ISO of it:

Code:

$ mkisofs -r -o brun.iso brun.mkv
I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage: Value too large for defined data type. File brun.mkv is too large - ignoring

Any solutions? I found some old patches for genisoimage, but I wonder if there's an other way.

You might take a look at this. If I were you, I’d opt for using a UDF filesystem instead.

Huh. I passed -udf option to mkisofs, and got the same message. If you have another pointer, I'd appreciate it

Ok. Here’s the thing—pay attention

: First, what you’re using is not mkisofs, but the mkisofs-derived genisoimage (which you already acknowledge). Only mkisofs (from cdrtools-2.01.01a32 or later) has the ability to write multiple extents as described in the article. To use this functionality, you have to enable iso-level 3 or 4 (the latter of which is really a pseudo-iso-level). For example this works on my system (with vanilla cdrtools-2.01.01a34):

Code:

$ ls -lh big.file
-rw-r--r-- 1 osor users 4.4G 2007-09-05 22:51 big.file
$ mkisofs -iso-level 3 -o big.iso big.file
Setting input-charset to 'UTF-8' from locale.

Regardless of your ability to create it, you’d currently have a hard time trying to read such an image from linux.

Second, udf support in mkisofs is poor (and udf support in genisoimage is extremely poor). There is no way to make a standalone udf image using mkisofs. The best you can do is make a hybrid, in which case you still need cdrtools-2.01.01a32 or later and you still use “-iso-level 3” for the multiple extents in the iso part.

So when I suggested udf, I meant using udftools, which is (AFAIK) linux-only.

Thanks for this explanation... It is very appreciated
