Could not locate OpenAL library (32/64 Bit issue?)

Yves_Tanas · January 20, 2015, 10:45am

I have searched a lot for this, but i can’t find, what might could help me.
I am trying to use the example for video and audio capturing and don’t need that much,
just capture the screen and record that audio.
Even if i copy over Advanced.java into my project i am running into this:

I know now, that it should have something to do with the VM i am using.
I am running on Win7 64-bit, JMonkeyPlattform 64-bit but both - java8 32-Bit and java8 64-Bit result in that error.

As i am using JavaFX too, i have to take one of that 8er-Versions…

Any idea how i can get rid of this problem ?

Seems like a common issue based on a quick google search. Make sure the sound is working on the PC first, otherwise, jME may need to update to a newer OpenAL version (maybe with LWJGL3?)

I have used the Sample for javafx to play a videofile on a quad, which sits now nicely in the background.
this is working fine - playing video and doing sound.
but if you may ask - even if i don’t initialize that feature into the SimpleApplication, i run into this error.
It also happens, when i only try to add that state tot the statemanager given as the most easiest example.
i really think, the clou should be that native 32/64 bit stuff, all the other problems are mostly related to that, but by the hell, a real solution is not really found.

Finally it really had something to do with a messed up system. I didn’t get out what the problem is, but finally after a clean install (which i had in mind for other reason before) now everything is working.
So i can only say, i really smell, this was an issue due to a bad mixing of 32-bit and 64-bit stuff, but i couldn’t find that out.
Now everything works and i will not change anything further ^^

Edit: I correct
stateManager.attach(new VideoRecorderAppState()); //start recording
works as said

public class Advanced extends SimpleApplication {…} results in

Well - Now i marked the problem !

Read another bit more about that aurellem stuff and he says:
"One concern:

In order to support Audio capture, it was necessary to make my own version of OpenAL-soft. This project is contained in audio-send: log above. While the code should compile fine on any system (it’s just openal-soft with some things removed, and one portable C file added), I don’t have the resources to compile it for every OS/architecture that JME3 supports. Is there already a system in place to compile native libraries for all the different platforms?
"

So there are two OpenAL versions in the project, one from lwjgl inside jme-lwjgl-natives.jar, which is used and the other, which should be used is sitting in “audio-send-natives.jar”

Is there nobody having problems in streaming video from inside you game environment or do you all have a better solution than using this ?!?
I think to make some previews and demovideos this is usable, but it doesn’t work …
