Hi,

trying to open http://www.mkonrad.net/projects/ogles_gpgpu.html leads to redirection to incorrect address https://mkonrad.netprojects/ogles_gpgpu.html. I guess something wrong with site configs (?)

OpenGL error in OGVideoProcDroid example (Android 4.4)

Hi,

I'm trying to run OGVideoProcDroid example on my Android device and got runtime error. Here are the steps to reproduce:

• Available targets

[ogles_gpgpu/examples/android/OGVideoProcDroid]> ./android list targets
Available Android targets:
----------
id: 1 or "android-19"
     Name: Android 4.4.2
     Type: Platform
     API level: 19
     Revision: 4

• android update

[ogles_gpgpu/examples/android/OGVideoProcDroid]> android update project --target android-19 --path . --name OGVideoProcDroid
Updated project.properties
Updated local.properties
Updated file ./build.xml
Updated file ./proguard-project.txt

• build

[ogles_gpgpu/examples/android/OGVideoProcDroid]> ndk-build
...
[...] Compile++      : og_jni_wrapper <= memtransfer_android.cpp
[...] SharedLibrary  : libog_jni_wrapper.so
[...] Install        : libog_jni_wrapper.so => libs/mips/libog_jni_wrapper.so

• create APK

[ogles_gpgpu/examples/android/OGVideoProcDroid]> ant debug
...
-do-debug:
 [zipalign] Running zip align on final apk...
     [echo] Debug Package: /.../bin/OGVideoProcDroid-debug.apk
...
-post-build:

debug:

BUILD SUCCESSFUL

• install

[ogles_gpgpu/examples/android/OGVideoProcDroid]> adb -d install -r bin/OGVideoProcDroid-debug.apk
4304 KB/s (1983478 bytes in 0.449s)
  pkg: /data/local/tmp/OGVideoProcDroid-debug.apk
Success

I've put some extra log messages (see my branch), look like it's crashing in camTexture.updateTexImage() method:

I/CamActivity(18175): Entering onFrameAvailable
I/CamActivity(18175): Try updateTexImage
W/Adreno-ES20(18175): <core_glBindTexture:572>: GL_INVALID_OPERATION
E/GLConsumer(18175): [unnamed-18175-0] bindTextureImage: error binding external texture image 0x5: 0x502
D/AndroidRuntime(18175): Shutting down VM

Thanks, Ruslo

Race condition in example OGVideoProcDroid

Two threads can simultaneously read/modify imgData variable. This may lead to synchronization errors. I can reproduce such error by adding delay to the update method: https://github.com/ruslo/ogles_gpgpu/commit/efed7c73d234f2814092e34e478d270a40b7c36f

Error doesn't occurs after synchronization code added: https://github.com/ruslo/ogles_gpgpu/commit/28e45d17cabce711ed461aa77b375af8e064ca6c (fix will look different after this change).
