The surfaceflinger API is not yet stable and only software that is signed with the system builder key can access it. The ndk has a few sample for gles and bitmap api, which I will take a look at next (<a class="moz-txt-link-freetext" href="http://developer.android.com/sdk/ndk/overview.html#samples">http://developer.android.com/sdk/ndk/overview.html#samples</a>).

These are the modifications: 1.) inside the gstramer_ndk_bundle dir get gst-plugin-gl and patch it  git clone git://<a moz-do-not-send="true" href="http://anongit.freedesktop.org/gstreamer/gst-plugins-gl" target="_blank">anongit.freedesktop.org/gstreamer/gst-plugins-gl</a>  git am 0001-build-Androigenizer-build-boilerplate.patch 2.) patch jni/Android.mk (0002-include-gst-plugins-gl.patch) 3.) build Right now one showstopper gst-plugin-gl support GL or EGL only via X11 as it seems. configure:22715: checking for eglGetError in -lEGL configure:22740: /home/ensonic/android/ndk/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc -std=gnu99 -o conftest -nostdlib -Bdynamic -Wl,-dynamic-linker,/system/bin/linker -Wl,--gc-sections -Wl,-z,nocopyreloc /home/ensonic/android/ndk/platforms/android-9/arch-arm/usr/lib/crtbegin_dynamic.o /home/ensonic/android/ndk/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.4.3/libgcc.a /home/ensonic/android/ndk/platforms/android-9/arch-arm/usr/lib/crtend_android.o -I/include -I/include -I/home/ensonic/android/ndk/platforms/android-9/arch-arm/usr/include -I/home/ensonic/android/gstreamer_ndk_bundle/jni/../libid3tag -I/home/ensonic/android/gstreamer_ndk_bundle/jni/../libmad -I/usr/include -I/usr/include -lc -ldl -L/home/ensonic/android/ndk/platforms/android-9/arch-arm/usr/lib -L/home/ensonic/android/gstreamer_ndk_bundle/obj/local/armeabi -L/home/ensonic/android/gstreamer_ndk_bundle/jni/../libs -Wl,--warn-unresolved-symbols conftest.c -lEGL    -L/usr/lib   -lX11 -L/usr/lib   -lX11 >&5 /usr/lib/libX11.so: file not recognized: File format not recognized After applying HACK.patch it configures, but I have to figure how to convince ndk-build to try building it... Also in the long run it looks like we wound need a new GL_BACKEND=xxxES2, julien any opinion? Stefan </blockquote> </div> </div> </blockquote> </body> </html>
