CEGUI Audio Plugin's
« on: December 09, 2005, 06:18:56 PM »
I've made some progress on implementing an audio plugin system for the CEGUI demo.. This way, multiple audio systems can be compiled at the same time and tested via a CEGUI runtime selection menu. I should be updating cvs this weekend.

Currently though, I only have the Base SoundManager and Dynamic Lib loading code done. Next step is to actually make the seperate sound dll's. Shouldn't take to long - just a matter of setting up the project files.

Ok, well, I've managed to throw the Fmod audio into a plugin lib (and it works like a champ!) :D .. Now, I just need to tweak a few more things and then add the OpenAL (updated) code into an openAL audio module dll. Perhaps more audio modules can be written and added to the list eventually.

well, I already have an audio subsystem for my project (using openal). Would I have to mesh it in with the plugin or what exactly ?

This is part of the CEGUI demo as has no bearing on your app at all. It does not change the interface of the Plugin.

A little update:
I've updated tagged cvs prior to updating to alpha, so those not wanting this can check out "alpha" ogreaddons/videoplugin/CEGUI_TheoraDemo version you will get the old one. CVS Head now contains (and is unstable because of) the new Audio Plugin System.. I still need to tweak some settings and update the linux build system.

Ok, CVS head the CEGUI demo now supports loading/unloading different modules at runtime. I still need to work on the selection higlite of the listboxes, but, trust me, when you click on it, it is highlited :D.

Also, The OpenAL code has a nasty crash when unloading a clip.. I think it might be related to using a framelistener there.. I'll have to investigate further. And, I also noticed horrible stuttering when using openAL, perhaps I need to up it's buffer size - something else to look into.

I have just commited the new Linux build environment so now Linux users can also try out the new plugin based audio system.. Currently only though, Fmod builds.. I promise I will get openAL working on linux here too (just give me a day or so :D ). It installs the Fmod Sound module (named FMOD_MOD.so) to /usr/local/lib where it should be easily found and opened with Ogre's dynlib load stuff - works great here. If it does not work for you, you need to add that path to where so's can be found on your system (I'm not a linux export - LD_LIB_PATH? or something)) or edit the makefile.

Next on the agenda is to get OpenAL working on Linux and not crashing anymore on windows.

OpenAL now works (better then the windows counterpart) on Linux!

Only thing i have left to do on that is fix a crash with openAL on Windows.. and make the configure scripts on Linux gracefully find/build the Fmod and/or OpenAL modules depending on if it can find fmod lib/openal libs.
