Image format 'Depth24' is unsupported

[ndebruyn]

Hi team,

I started playing with jME3.1-Beta2 and android and I am getting the error below:

My Setup:

1. Created a Basic Test Android Application.
2. Added a FXAA filter to the scene.
3. Converted my app to run android.
4. Runs fine on Window, but on Android I get this error.
5. Device Galaxy Note 4
6. Settings on android:

eglBitsPerPixel = 24; eglAlphaBits = 0; eglDepthBits = 16; eglSamples = 0; eglStencilBits = 0;

com.jme3.renderer.RendererException: Image format 'Depth24' is unsupported by the video hardware.

I debugged my code and it seems that something is overriding the eglDepthBits = 16; to 24

I will try and find it. Might be on my side but I do not change that specifically.

[ndebruyn]

Is there anyone out there that have experienced this problem before…

I am still stuck.

Okay for those interested, I made some progress…

1. I had to force the FilterPostProcessor’s depth texture image format to Depth16:

fpp.getDepthTexture().getImage().setFormat(Image.Format.Depth16);

2. Had to force the Filter Texture image format also but to RGBA8:

if (fpp.getFilterTexture() != null) {
                fpp.getFilterTexture().getImage().setFormat(Image.Format.RGBA8);
            }  

3. Then on my filters I had to override the default image formats:

    @Override
    protected Image.Format getDefaultPassDepthFormat() {
        return Image.Format.Depth16;
    }

    @Override
    protected Image.Format getDefaultPassTextureFormat() {
        return Image.Format.RGBA8;
    }

That kind of helped with most of my filters except the one’s which requires a depth texture:

protected boolean isRequiresDepthTexture() {
        return true;
    }

Any advice on the last point??? @nehon

[nehon]

Sorry I missed this post. I think I remember we changed the Depth precision to 24… but it was a long time ago… I guess we could check i f the hardware supports it an fallback to lower values… the “Depth” format is already supposed to pick the best fit… but I think it just pick the first fit and was selecting Depth16 even when depth24 was available.
It’s safe to do it as you did, even if I reckon it’s a bit cumbersome.

[ndebruyn]

Thanks nehon for the feedback and I can work with it as is for now, but I think for future users of jME3.1 and Android that it should be fixed.

Thanks again.

[fba]

I’m going through the same issue, but the workaround from @ndebruyn did not work for me since ‘fpp.getDepthTexture()’ and ‘fpp.getFilterTexture()’ return null. I’m deploying my app to a real device, not an emulator. Does anyone know how to fix it?

[NemesisMate]

Did you manage somehow to make any filter work on Android?

Currently, I’ve tried your solution and it worked to remove the “Image format ‘Depth24’ is unsupported” but it started to trow a java.lang.IllegalStateException: Framebuffer has erronous attachment, which seems to be a known issue:

Constructing frameBuffers on android throws exception

So I set up a framebuffer for rendering to a texture in my app. On PC it works just fine, but on android I get this: E/com.jme3.app.AndroidHarnessFragment(12372): SEVERE Exception thrown in Thread[GLThread 4024,5,main] E/com.jme3.app.AndroidHarnessFragment(12372): java.lang.IllegalStateException: Framebuffer has erronous attachment.

and from nehon:

@nehon

tbh the post process were never tested on android and the ones that works do only incidentally.

what doesn’t give me too much hope in this issue. I’ve tried with FXAA and the CartoonEdgeFilter so far, both with the same result.

The full stack trace in this case is (almost identical to the one in the linked posts):

This should be fixed on latest master:

[NemesisMate]

It still throw the same issue for CartoonEdge (just some line number changes) and a different one for FXAA:

Hi,

I want to learn how this OpenGL texture support work too :). So, does my problem below would be fixed with the new master as well? Could it be that OpenGL team does not know that something does not work perfectly with my old laptop?

Here it is. ant -f /home/erick/NetBeansProjects/JmeTests -Djavac.includes=jme3test/water/TestMultiPostWater.java -Dnb.internal.action.name=run.single -Drun.class=jme3test.water.TestMultiPostWater run-single init: Deleting: /home/erick/NetBeansProjects/JmeTests/build/built-jar.properties deps-jar: Updating property file: /home/erick/NetBeansProjects/JmeTests/build/built-jar.properties Compiling 1 source file to /home/erick/NetBeansProjects/JmeTests/build/classes Note: /home/erick/NetBeansP…

I have multiple laptop and PCs, but that laptop is the one with oldest hardware, which I use to test my mininum hardware requirement.

Thank you.

[Momoko_Fan]

Yes that one should be fixed as well

[sethanath]

Thank you.
