在 android 中使用 gstreamer 插件不好

Question

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?

Answer 1

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)

Answer 2

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
