I found out what was causing the problem: the width and height that were passed to the effect.apply() were different than the width/height of the texture at the time of creation. After fixing that I can now see some sensible output.
I haven't seen the errors that I mentioned above as of the fix; so, I'm still not sure if the errors have the same cause. --Hossein On Apr 13, 6:55 pm, hmohtasham <[email protected]> wrote: > Oh, I forgot to mention that the app occasionally crashes with the > following error: > > 04-13 09:10:33.890: E/AndroidRuntime(17201): FATAL EXCEPTION: GLThread > 2351 > 04-13 09:10:33.890: E/AndroidRuntime(17201): > java.lang.RuntimeException: Applying effect in wrong GL context! > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > android.media.effect.EffectContext.assertValidGLState(EffectContext.java: > 112) > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > android.media.effect.FilterEffect.beginGLEffect(FilterEffect.java:67) > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > android.media.effect.SingleFilterEffect.apply(SingleFilterEffect.java: > 71) > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > com.experimental.camera2gl.GLES20TriangleRenderer.onDrawFrame(GLES20Triangl > eRenderer.java: > 208) > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java: > 1462) > 04-13 09:10:33.890: E/AndroidRuntime(17201): at > android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1216) > > and also sometimes the following error with no crash: > > 04-13 09:51:52.780: E/MCA(27518): GL Error: Operation 'Popping Vertex > Attributes' caused GL error (0x506) > > Thanks > > --Hossein > > On Apr 13, 5:17 pm, hmohtasham <[email protected]> wrote: > > > > > > > > > Greetings! > > > I'm experimenting with various effects provided in the android.media.* > > package and I > > have been able to get some output; however, it seems that the > > processed texture > > (the output of the effect) is stretched to the right in a way that > > part of the right side > > of the input is not seen (cropped). > > > I draw two quads one textured with input image and the other with the > > output, > > within the same OnDrawFrame().
