Intro
Although vlc is moving away from wxwidgets this is an attemp to move wxwidgets towards vlc (libvlc to be more precise).. The libvlc API is fairly new and VERY promissing.. It exports ALL the functionality of vlc into a nice c API . On the other hand wxWidgets is a very rich [1] ( and also community based ) growing X platform library. It covers the 3 basic platforms (MSW, LINUX, MAC) and more[2]..
wxVLCBackend
wxVLCBackend v2 is a wxMediaCtrl backend. The latter is a stub media player in wxWidgets and provides an interface for various kinds of backends (gssteamer, wmp,...). wxVLCBackend maybe integrated in the official wxwidgets code.. The backend code provides a guide to integrade libvlc in other c/c++ gui frameworks as well. In fact the only TRICKY part was to get a low-level hadle for the drawable surface.
Right now (29/10/08) The code is not mature enough for publication. There are some stability issues. To correct them i've created a mini (Poc) wxWidgets based app to isolate these issues, wxvlc_test.
wxvlc_test
wxvlc_test is a simple wxWidgets based app. It has a textbox where you give a media filename and a play, stop button to control playback. In my tests wxvlc_test crashes when starting playing ( somewhere inside libavcodec library with no other dubuging symbols ) *some* avis.. On the other hand vlc plays these same files smoothly.
- Tests were done on vlc-0.9.5
My intentions for this publication are : a) to test the glue code on other systems ( my tests are on linux ONLY so dont ask me, but windows could be tested too ) b) to check the glue code correctness by a vlc internalls well-knower (maybe i miss something, cause i cant explain that libavcodec crashes)
Information for wxvlc_test is provided in the README as well
wxvlc_test v0.1 source
The program is provided under patch format here. Copy and paste the following to a new patch file ( say wxvlc.patch) and "apply" it with patch -Np0 < ../wxvlc.patch this will create a new dir with all the needed files inside

+-- INTRO
+wxvlc_test v0.1
+
+This is a mini library for libvlc integration into wxWidgets apps . Its a poC
+ and is intented to test it for stability. It is part of the wxVLCMediaBackend v2
+ for integration into wxMediaCtrl as a Bakend...[It is not published yet (10.08)]
+
+
+--USAGE
+-Make sure you have wxWIdgets 2.8 installed (don't know for later versions,
+but i think 2.6 should work).
+-Make sure you have vlc installed.. Ok we test on linux, so it means libvlc is
+ in path as well as the plugins.
+ You need to comment some lines at Makefile ( Noted) for windows and make
+ sure the linker can "see" libvlc.dll. It is not tested so don't ask me .
+
+$make
+$./wxvlc_test
+
+
+--ISSUES
+It crashes with some AVI files. Dont know what it is ...
+
+
+-- LIC
+-this code is left to the "public" as is without ANY waranty, the authors CANNOT be
+ held responsible if it blows your house or something...
