Getting ERROR: Unable to get a valid OpenGL ES 2.0 config, neither Fastest nor Best found! Bug. Plea

iwgeric · September 8, 2012, 9:20pm

I had a BasicGame app that runs fine on my phone, but when I install to tablet, I get the following in the logcat:

ERROR: Unable to get a valid OpenGL ES 2.0 config, neither Fastest nor Best found! Bug. Please report this.

Logcat is below. The app runs fine on Motorola Bionic with 2.3.4 and errors out on Motoloa Xoom with 4.0.4.

[EDIT] Thought I should also mention, running from jMonkey SDK (engine is latest build from source) and have not updated Android SDK for a long time using Android SDK 16.

Update: When I switch to any of the following

[java]

eglConfigType = ConfigType.BEST_TRANSLUCENT;

eglConfigType = ConfigType.FASTEST;

eglConfigType = ConfigType.LEGACY;

[/java]

it works.

It only fails when I use

[java]

eglConfigType = ConfigType.BEST;

[/java]

I’ve tested jME3 before on a Xoom with Android 4 and it worked fine. This is a rather odd bug to say the least.

iwgeric · September 10, 2012, 12:26am

I’m pretty sure I’ve installed something on my Xoom before as well. Maybe something changed with AndroidConfigChooser or ComponentSizeChooser. I seemed to remember @nehon changed something not that long ago, but can’t seem to remember what it was. Not sure if that is related or not. I’m trying to debug this, but not getting anywhere yet.

What’s the difference between the different configurations? Is it really only used in the findConfig method of AndroidConfigChooser?

[java]

public boolean findConfig(EGL10 egl, EGLDisplay display) {

ComponentSizeChooser compChooser = null;

switch (type) {

case BEST:

compChooser = new ComponentSizeChooser(8, 8, 8, 0, 32, 0);

choosenConfig = compChooser.chooseConfig(egl, display);

if (choosenConfig == null) {

compChooser = new ComponentSizeChooser(8, 8, 8, 0, 16, 0);

choosenConfig = compChooser.chooseConfig(egl, display);

}

logger.info("JME3 using best EGL configuration available here: ");

break;

case BEST_TRANSLUCENT:

compChooser = new ComponentSizeChooser(8, 8, 8, 8, 32, 0);

choosenConfig = compChooser.chooseConfig(egl, display);

if (choosenConfig == null) {

compChooser = new ComponentSizeChooser(8, 8, 8, 8, 16, 0);

choosenConfig = compChooser.chooseConfig(egl, display);

}

logger.info("JME3 using best EGL configuration available here with translucent pixels: ");

break;

case FASTEST:

compChooser = new ComponentSizeChooser(5, 6, 5, 0, 16, 0);

choosenConfig = compChooser.chooseConfig(egl, display);

logger.info("JME3 using fastest EGL configuration available here: ");

break;

}

if (choosenConfig != null) {

logger.info("JME3 using choosen config: ");

logEGLConfig(choosenConfig, display, egl);

pixelFormat = getPixelFormat(choosenConfig, display, egl);

clientOpenGLESVersion = getOpenGLVersion(choosenConfig, display, egl);

return true;

} else {

logger.severe(“ERROR: Unable to get a valid OpenGL ES 2.0 config, neither Fastest nor Best found! Bug. Please report this.”);

clientOpenGLESVersion = 1;

pixelFormat = PixelFormat.UNKNOWN;

return false;

}

}

[/java]

Looks like AndroidConfigChooser was changed back in June to change BEST to an opaque background. Maybe there’s something related to that here.

Momoko_Fan · September 10, 2012, 2:21am

From a quick look at the source I can already tell there’s going to be some issues. The current config choosers try to find an exact match for color/alpha which is definitely not guaranteed. On NVIDIA platforms I can guess they optimize the common case (RGBA / 32 bit) by only exposing the RGBA8 format and not exposing RGB8, there’s your bug.

iwgeric · September 10, 2012, 2:50am

I figured out why it is failing. It is as you said. I put some debug in to list all the supported configs that match the 8,8,8,0,16,0 config spec.

Below is the list that was returned. As you can see, there is not an exact match so it fails.

Should it not try to exact match the alpha but rather grab an alpha 0 config if it can while allowing the non-0 alpha configs to be used?

Exactly. You can actually see it does this for depth and stencil but incorrectly, it chooses the first config that has these either greater or equal, it should try to choose an exact matching one, and only then try to find a higher one.

nehon · September 10, 2012, 6:48am

I just changed the BEST to opaque yes as it was transparent before. This gives a big boost on most device since the pixel doesn’t have to be read again for transparency.

Most games does not overlay the surface on top of android UI, so opaque is perfectly fine.

Whatever you do, for best config, always try to have an alpha channel to 0, just check if the format is available and fallback to the first found as it seems to be the problem.

iwgeric · September 10, 2012, 11:59am

@nehon @Momoko_Fan

Based on the fact that the configs are already sorted by the chooseConfig method, I’ll make a change that tries to find an exact match for r, g, b, a, d, s and if not found, use the first config in the array.

That sound ok?

nehon · September 10, 2012, 12:04pm

@nehon @Momoko_Fan

So I made the change described above, but noticed that on my phone, the first config does not contain a 0 length alpha buffer, while a later one has an alpha size of 0 with the stencil size of 8.

My question is: Is it more important to have the 0bit alpha size with maybe > 0bit stencil size, or use the first one that has a 8bit alpha with a 0bit stencil? I don’t think we want to lose the benefit of the 0bit alpha which means picking one of later configs.

The first logcat below is what is returned on my phone. When jme tries the first BEST config (32bit depth), it returns 0 configs. Then when it tries again with 16bit depth, it returns the configs below. Notice that the first one has an 8bit alpha, while the 3rd config has an 0bit alpha and 8bit stencil.

The second logcat is from my Xoom which also returns 0 configs for the 32bit depth, but does not have any configs available with a 0bit alpha.

I’m thinking that I need to do the exact match first and then try to pick one with 0bit alpha next, and then finally pick the first config. Do you agree?

A stencil of 8 is preferable to an alpha of 8 because alpha of 8 implies possibly blending with the background which would be slow on some platforms. Generally 8 bit stencil is combined together with the depth buffer and since jME3 doesn’t use it, there’s no performance loss.

Thanks what I thought, but wanted to make sure.

This means I’ll do 2 passes through the config list.

Pass 1 is to try to find an exact match.

Pass 2 will look for an exact match of RBGA and accept whatever D and S is there as long as they are > the config spec values (I believe this is what was done originally)

Fall back will be to use the first config in the list.
