Re: [osg-users] Android build failure with Android NDK r13
Hi, everything works fine for me following the same instructions with the same osg/ndk versions. Maybe your toolchain is actually broken.

Uh, right...
It is src/osgPlugins/ffmpeg/FFmpegDecoderAudio.cpp. I'm attaching it

[osg-users] Troubles with the Texture2D serializer when _image is an ImageSequence
Hello everyone,
I've discovered a problem with the Texture2D serializer that occurs when the
associated image is an instance of an osg::ImageSequence.
I think this happens because the ImageSerializer::read method calls the
InputStream::readImage without ensuring that the object is actually an
osg::Image, producing a read error.
Can someone evaluate my observations?
I use OSG-3.0.1, but in 3.1.2 ChangeLog file I have not found anything
about it.
This is the osgviewer output:
[martino@slack] osg_image_sequence $ osgviewer graph.osgt
InputStream::readObject(): Unsupported wrapper class
osg::StateAttributeCallback
Warning: Could not find plugin to read objects from file "".
AsciiInputIterator::readProperty(): Unmatched property }, expecting Value
I attach two files:
write_graph.cpp produces graph.osgt
graph.osgt contains the ImageSequence that osgDB::readNodeFile cannot
read
Thanks you all,
Martino

Re: [osg-users] More Information about the osgAndroid [help]
Sorry for my late reply, Like in any other C++ application, you must specify the correct path to your headers. By copying the osg headers in the "/home/nearchos/OpenSceneGraph_Android/make_test/include" folder the compilation process should succeed. Alternatively, you can modify the Android.mk file at line 17: LOCAL_C_INCLUDES := /your/path/to/osg/include Note that the Android emulator does not support GLES 2.0, so you have to run the example in a concrete device.
