I want to write a VLC modules who can read DCP (format for digital cinema)
I'm in the case of unencrypted DCPs;
Basically a DCP is a directory with :
- XML files for meta-data
- An MXF file for images ( JPEG2000 images)
- An MXF file for sound ( WAV format)

The avcodec can read MXF files.
My question is about architecture of the module.

The choice of access, demux or access_demux.

For input something like vlc dcp:///path_to_dcp_directory.

In the access file, I want to  open the 2 MXFs files . How I open It ? 
can I call internally the access/file module. One for each kind of media ?
Then how  i can link it to a demux ? As I have 2 separate files for 
video/sound, maybe I don't need this function ?
Then send these 2 MXF file to libav for decoding. But where I have to 
manage synchro of sound and image ?

Sorry for having all those questions, but I didn't easyly find entry 
points. Did some video format can be close to dcp format ?
