[Banshee-List] Vlc MediaEngine 0.0.1

["Timothy J Fontaine" <tjfontaine gmail com>]

While working on a different plugin for Banshee I became frustrated with the GStreamer backend (the problem is in libmms in particular but I was tired of fussing with it), and my inability to debug it, I was also fed up with trying to make the Xine backend bend to my will; So, in true OSS fashion I decided to reinvent the wheel (somewhat). Therefore I present to you banshee-engine-vlc (
http://tophat.atxconsulting.com/~tjfontaine/banshee-engine-vlc-0.0.1.tar.bz2) This MediaEngine plugin uses the newer libvlc api available since 
0.8.5 (i.e. not the same api jlj used for the sharpmusique stuff), the engine was put together in about 3 days, so caveat emptor. I've tested with 0.11.3 on Feisty, and SVN trunk things seem to run smoothly, it *should* be able to be a cdda backend but I don't listen to cds so I haven't really tried to work with that. Below you'll find the README.

I'd appreciate any feedback/flames. Thanks

Vlc Banshee MediaEngine Plugin

-----------------------------------------

This plugin requires the libvlc api which was made available starting with
version 0.8.5, I tested with 0.8.6. The filenaming scheme is such that I could
build my test.cs file without including the Banshee stuff, so the Vlc*.cs files
are largely standalone and could be used elsewhere in applications that want to
make use of Vlc in managed code.

Caveats:
Different flavors distribute libvlc in different forms, and my autofoo is not
such that I felt like detecting such things at build time, so if you experience
a segfault on startup it's likely you need to futz with the dllmap'ing and make
sure you actually have libvlc installed.

At the time of this writing (2007-01-10) the engine worked without issue with
other backends in version 0.11.3, however SVN Trunk of banshee and B.ME.Vlc had
a slight runtime conflict with the builtin GStreamer backend and can be solved
with the following diff:
