[Mxflib-developers] Overriding file IO in mxflib

[Mathew S. <mat...@eu...>]

Hi all,

I am currently working on wrapping mxflib so that it can be used as a 
plugin to a gstreamer pipeline (for those that don't know gstreamer, its 
an open source direct-show style streaming media framework.  See 
http://freedesktop.org/~gstreamer ).

For me to be able to do this, I need to be able to abstract the file IO 
functions.  There seems to be some support to do this already through 
use of the MXFLIB_NO_FILE_IO, but under linux, using this flag causes 
problems with klvlib's file io functions as KLVFile is hard coded to FILE*.

Is anyone aware of this problem?  Is there a recommended solution to 
this problem?

Could I suggest a list of callback functions to be used (much as in a 
linux device driver) with a set of defaults defined for the currently 
supported platforms.  This should also allow the removal of duplicate 
function declarations in mxflib's system.h.

I am willing to supply a patch to achieve this (although I am only able 
to test under Linux here).

Regards,

Mat
