[vlc-devel] [PATCH] A new Zip demuxer for VLC

Hi guys,

This patch adds a new Zip demuxer for VLC.
It does not work in a way similar as the RAR filter, as it is based
on 2 modules: access + demux.

Features:
- It can read albums in a Zip file, and it might be used in the future
   to read subtitles in .zip archives.
- It supports reading medias in a zip on any accessible support
   (using core inputs), eg. zip over http.
- It supports seeking (I think not fast-seeking).

Limitations:
- It does not support multi-part archives.
- It does not [yet] support encryption, but if this feature is wanted, then
   this can 'easily' be added (see crypt.h).
- Because of the MRL format, it does not support reading a media in a zip
   in a zip (no typo here).

Note:
- The second part of the patch is actually a copy of
   modules/skins2/unzip/*  to  modules/demux/zip/

Even if I have Git access, I prefer not committing this before review.
Thanks in advance for your remarks and suggestions.

Best regards,
