MP4ReadProvider still causes direct call to stat64

[Google Code Exporter]

What steps will reproduce the problem?
1. use mp4readprovider with custom open/read/seek/close implementations
2. do NOT use a file in the underlying file system (hence custom impls)
3. mp4v2 calls stat64 (according to strace) on the non-existing file and then 
fails to open the file (presumably because it doesn't get the file size)

What is the expected output? What do you see instead?
I had hoped you'd just run assuming 'infinite' file size until read fails;
alternatively, you need to modify the API to allow me to also provide a 'stat' 
replacement.


What version of the product are you using? On what operating system?
2.0.0, Debian.

Please provide any additional information below.
I was trying to use MP4v2 in GNU libextractor.

Totally agree; this is something about the read/writer provider interfaces that 
I've found nonsensical; open/read/seek/close is available, but not file size of 
all things.
