I don't know exactly, but is it a good idea to start to write a plugin now??

Because everything in Myth should be changed to the libmythui I think I
would wait for a release of the plugins using this...

Get a copy of  mythplugins-0.18.1.tar.bz2 from

Look at the source for mythdvd. In the file main.cpp you'll see there 
are three functions declared extern "C" { }. They are 'mythplugin_init', 
'mythplugin_run', and' mythplugin_config'. These are the entry points 
that MythTV uses to connect to any plugin. mythdvd is probably a good 
example to start with. You'll see that it calls other functions within 
the main to implement the dvd plugin, but that it starts with above 
three functions.

Figure out what you want to do in your plugin, and start writing the 
init, run and config functions using mythdvd as an example. Once you 
have compiled the plugin, as a dynamically loaded library (for example, copy it to the mythtv/plugins directory. On my machine 
it's /usr/local/lib/mythtv/plugins. It may be somewhere else such as 
/usr/lib/mythtv/plugins on your machine.

You should now be able to connect to your plugin through a menu item, 
for example.
