Yes I saw that. I will take another look once I am done fixing the openGL
playback plugin. That will be good start, but it has to work for all audio
players in LiVES, pulseaudio also. But it should not be too difficult,
there is already support in LiVES for feeding audio to LADSPA plugins for
example.
There is also the issue of feeding keystrokes to projectM. This is not hard
to do programatically, but still there are two things to consider:
- a way for plugins to notify the host that they can accept key presses
- a way for the user to switch between keypresses going to the LiVES
application and a specific effect/plugin which is running.
A kind of kludge is for the plugin to have a dummy text entry parameter,
and then use that to capture keypresses. Then you can set the key grab to
that effect, press tab and it should work. But there may be a better way.
Showing a control window is possible but problematic for a number of
reasons, mainly it is not good in single monitor mode.
Regards,
Gabriel.
