Using gstreamer plugins bad in android

I am trying to show h264 encodes streams inside an android application using the GStreamer SDK and Android NDK.
My Android.mk looks like:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := App
LOCAL_SRC_FILES := App.cpp
LOCAL_SHARED_LIBRARIES := gstreamer_android
LOCAL_LDLIBS := -llog -landroid
include $(BUILD_SHARED_LIBRARY)
ifndef GSTREAMER_ROOT
ifndef GSTREAMER_ROOT_ANDROID
$(error GSTREAMER_ROOT_ANDROID is not defined!)
endif
GSTREAMER_ROOT := $(GSTREAMER_ROOT_ANDROID)
endif
GSTREAMER_NDK_BUILD_PATH := $(GSTREAMER_ROOT)/share/gst-android/ndk-build/
include $(GSTREAMER_NDK_BUILD_PATH)/plugins.mk
GSTREAMER_PLUGINS := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_EFFECTS) $(GSTREAMER_PLUGINS_NET)
GSTREAMER_EXTRA_DEPS := gstreamer-video-1.0
include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk
Beacause of missing plugins-bad I get the following error:
priv_gst_parse_yyparse no element "h264parse"
My pipe looks like the following:
udpsrc address=192.168.0.1 port=5000 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink
So how can I include the gstreamer-plugins-bad into android build?

Try adding this line instead the one you have:
GSTREAMER_PLUGINS := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_CODECS_RESTRICTED)
Specifically this one should do the job $(GSTREAMER_PLUGINS_CODECS_RESTRICTED)

You can add this line :
GSTREAMER_PLUGINS := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_CODECS_RESTRICTED) $(GSTREAMER_PLUGINS_EFFECTS)
in your path : app/jni/Android.mk

Build Android OpenCV and FastCV

I am having issues when building OpenCV and FastCV as static libs. Here is my Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

OPENCV_INSTALL_MODULES:=on

OPENGLES_LIB := -lGLESv1_CM
OPENGLES_DEF := -DUSE_OPENGL_ES_1_1
else
OPENGLES_LIB := -lGLESv2
OPENGLES_DEF := -DUSE_OPENGL_ES_2_0
endif
LOCAL_MODULE := drive_assist
LOCAL_SRC_FILES += jni_part.cpp GridTracking.cpp CameraRendererRGB565GL2.cpp FastCVSampleRenderer.cpp CameraUtil.cpp
LOCAL_LDLIBS += -llog -ldl $(OPENGLES_LIB) -lfastcv
LOCAL_CFLAGS += -Wno-write-strings $(OPENGLES_DEF) -ffast-math -O3 -fopenmp -funroll-loops
LOCAL_LDFLAGS +=-O3 -fopenmp
LOCAL_CPPFLAGS := -O3 -flto -ffunction-sections -fdata-sections

LOCAL_CPPFLAGS += -fomit-frame-pointer -funroll-loops -ffast-math
LOCAL_CPPFLAGS += -mfloat-abi=softfp -DFPM_ARM -DNDEBUG
LOCAL_STATIC_LIBRARIES += libfastcv
LOCAL_SHARED_LIBRARIES := liblog libGLESv2
include $(BUILD_SHARED_LIBRARY)
I get weird undefined reference errors in the OpenCV native library, for example:
/Users/Razvan/Android/OpenCV-2.4.11-android-sdk/sdk/native/jni/include/opencv2/core/mat.hpp:353: error: undefined reference to 'cv::Mat::create(int, int const*, int)'

/Users/Razvan/Android/OpenCV-2.4.11-android-sdk/sdk/native/jni/include/opencv2/core/mat.hpp:367: error: undefined reference to 'cv::Mat::deallocate()'
The strange thing is that if I remove the FastCV stuff, OPenCV will compile and work perfectly. I do NOT want to use dynamic linking and the OpenCV manager. Does anyone have any suggestions for my issue?
Thanks!

Solved by changing the shared libs in Android.mk as follows:
LOCAL_SHARED_LIBRARIES += lopencv_java liblog libGLESv2

Android NDK & FFMPEG : findLibrary returned null

I am using this to build ffmpeg on ndk:
roman10's android ndk r9d - ffmpeg tutorial
The link shows how to compile, but its not clear how to use it. Can anybody guide me? Thanks.
After ndk-build from my project root i was able to generate .so files inside libs/armeabi and obj/local/armeabi.. Now I am getting findLibrary returned null?? What to do now?

LOCAL_MODULE:= libavutil
-->
LOCAL_MODULE:= avutil # libavutil.so
example (used to work):
https://github.com/18446744073709551615/reDroid/blob/master/jni/Android.mk
UPDATE:
Once again: you do not need the lib prefixes in library names; LOCAL_MODULE:= avutil will give you libavutil.so
At second, what parameter do you pass to loadLibrary()? Again, it should be "avutil" for libavutil.so.
If you have problems, the best way is to start with the hello-jni example in the NDK (your-ndk-dir/samples/hello-jni/)
/* this is used to load the 'hello-jni' library on application
* startup. The library has already been unpacked into
* /data/data/com.example.hellojni/lib/libhello-jni.so <== !!!!!!!!!!!!!
* at installation time by the package manager.
*/
static {
System.loadLibrary("hello-jni");
}
Once the example compiles and runs, you may add your libraries to it and have your stuff work.

You use name libavutil to refer to libavutil-54.so during ndk-build. This is fine, but the runtime lib is still called libavutil-54.so. Moreover, your other modules, including tutorial01, know it by this name, so renaming it in libs/armeabi will also be wrong.
You need something like
static {
System.loadLibrary("avutil-54");
System.loadLibrary("avcodec-56");
System.loadLibrary("avformat-56");
System.loadLibrary("swscale-3");
System.loadLibrary("tutorial01");
}
In recent version of Android, the system will automatically resolve the local external references, so it's enough to call
static {
System.loadLibrary("tutorial01");
}

Replace your
LOCAL_SHARED_LIBRARIES := avformat avcodec swscale avutil
with
LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil libavfilter libswresample
in Android.mk in your Jni folder.
And Load the libraries like below
static {
System.loadLibrary("avutil-54");
System.loadLibrary("avcodec-56");
System.loadLibrary("avformat-56");
System.loadLibrary("swscale-3");
System.loadLibrary("avfilter-5");
System.loadLibrary("swresample-1");
System.loadLibrary("tutorial01");
}

Are you sure that you are using a phone with an armeabi processor? Add the armeabiv7 in the Application.mk file and it will compile the required files for armeabiv7 phones in the libs folder.
APP_ABI := armeabi armeabi-v7a x86
This should work.

Would be really really gratefull if someone helped!

If you have the prebuilt static library for Android in $(LOCAL_PATH)/libxml2/libxml2.a, you can use it as is in your spice-android project,
LOCAL_STATIC_LIBRARIES += xml2
Instead of include $(BUILD_SHARED_LIBRARY) for xml2, use
LOCAL_SRC_FILES := libxml2/libxml2.a
include $(PREBUILT_STATIC_LIBRARY)
If you have a strong reason to use xml2 as a separate shared library, you need to add call
System.loadLibrary("xml2");
to your Java code (before loading libspice-android.so) and replace LOCAL_SRC_FILES := $(LOCAL_PATH)/libxml2/libxml2.a with
LOCAL_WHOLE_STATIC_LIBRARIES := $(LOCAL_PATH)/libxml2/libxml2.a

This is issue of linking shared libraries, you need to add LOCAL_LDLIBS += $(LIB_PATH) -lxm2 just before LOCAL_SHARED_LIBRARIES= xml2 .

UnsatisfiedLinkError In Android 4.4 libDevil cannot locate symbol "png_set_longjmp_fn"

I have an image converter app on google play that runs fine and well, it incorporates NDK for support of more file formats using the DevIL Image Processing library.
It wokrs fine on most devices but since Android 4.4 Kitkat came out, i've received emails and crash reports on Google Play Console especially from Nexus devices that have 4.4 and now other older devices that receive the update
Here is the crash report
java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "png_set_longjmp_fn" referenced by "libdevil.so"...

The app can't start and from my own debugging it's from the first lines of my MainActivity.java when loading libdevil
static {

after searching my entire jni folder for the png_set_longjmp_fn string, i found it in the following files in my libpng folder. Below are snippets.
pngerror.c
#ifdef PNG_SETJMP_SUPPORTED
/* This API only exists if ANSI-C style error handling is used,
* otherwise it is necessary for png_default_error to be overridden.

size_t jmp_buf_size)
{

Any help to make kitkat locate it is much appreciated.

Well from all my googling, I think Android 4.4 tries to link anything called libpng to its own libpng 1.2.46, My libpng 1.5.6 had the png_set_longjmp_fn symbols and the one 4.4 uses doesn't
So i went to my android.mk file and renamed libpng to libpngo as well as the system.load thingy in my mainactivity.
Works OK now.
