Hi,
Do you know how to import GStreamer into Android source code and configure Android. mk?
Best Regards,
Nancy
have you tried this?
https://gstreamer.freedesktop.org/documentation/tutorials/android/index.html?gi-language=c
Yes. I can use GStreamer on Android Studio successfully.
When I want to import GStreamer to Android source code, I cannot configure it correctly .
Android.mk under jni like this:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
ifndef GSTREAMER_ROOT_ANDROID
GSTREAMER_ROOT_ANDROID := $(LOCAL_PATH)/gstreamer-1.0-android-universal-1.22.6
endif
GSTREAMER_ROOT := $(GSTREAMER_ROOT_ANDROID)/arm64
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_PLAYBACK)
$(GSTREAMER_PLUGINS_CODECS)
$(GSTREAMER_PLUGINS_NET)
$(GSTREAMER_PLUGINS_SYS)
$(GSTREAMER_PLUGINS_CODECS_RESTRICTED)
opengl
G_IO_MODULES := openssl
GSTREAMER_EXTRA_DEPS := gstreamer-video-1.0 gstreamer-rtsp-server-1.0 gobject-2.0
GSTREAMER_EXTRA_LIBS := -liconv -lgstbase-1.0 -lGLESv2 -lEGL
include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk
include $(CLEAR_VARS)
LOCAL_MODULE := libandroid_camera
LOCAL_SRC_FILES := android_camera.c
LOCAL_SHARED_LIBRARIES := libgstreamer_android
LOCAL_LDLIBS := -landroid -llog -lcamera2ndk -lmediandk
include $(BUILD_SHARED_LIBRARY)
===============================================================
error like this ：
“libandroid_camera (SHARED_LIBRARIES android-arm64) missing libgstreamer_android (SHARED_LIBRARIES android-arm64)”
Here is my, very old version. But it still works. Maybe some parts are not needed anymore

Thank you for your help.
Can you tell me that the content of the last line in gstreamer_prebuilt.mk?
Default is “include $(BUILD_SYSTEM)/build-module.mk",
but build fail and error is ：
error: build/make/core/build-module.mk: No such file or directory
So I still cannot compile in the source code.
What exactly are you trying to do here? You say that this works in android studio. Are you running gradle directly? Or maybe even ndk-build directly? What environment are you attempting to run ndk-build in? Are you attempting to build as part of another project? AOSP perhaps?
I want to import my apk (which uses GStreamer and works well in Android studio) into the Android project (AOSP).
I see. You will need to rewrite GStreamer’s ndk-build integration for the specific environment provided by the AOSP build process. The default GStreamer ndk-build integration is not designed for that.
Okay, I got it.
Thank you.
