hello,ALL



i am a new learner of gstreamer, and in my program, i want use gstreamer in
android to send 6(D1) camera video.

i know the gstreamer.org support the NDk for android,but i do not want to
use the way of apk. i git ur demo source, and i want to configure it  in
android, i put it in /Android_src/external/ as gstreamer_top,and the
Android.mk like this:



$#############################

turkeyzhu at turkeyzhu:~/Android_src/external/gstreamEr_top$ less Android.mk

# This file is the top android makefile for all sub-modules.

LOCAL_PATH := $(call my-dir)

GSTREAMER_TOP := $(LOCAL_PATH)

include $(CLEAR_VARS)

include $(GSTREAMER_TOP)/gst/Android.mk

include $(GSTREAMER_TOP)/libs/gst/base/Android.mk

include $(GSTREAMER_TOP)/libs/gst/controller/Android.mk

include $(GSTREAMER_TOP)/libs/gst/dataprotocol/Android.mk

include $(GSTREAMER_TOP)/libs/gst/net/Android.mk

include $(GSTREAMER_TOP)/plugins/elements/Android.mk

include $(GSTREAMER_TOP)/plugins/indexers/Android.mk

include $(GSTREAMER_TOP)/tools/Android.mk

$#############################



oh i forgot, i use android4.2.2, i build it in Freescale i.mx6, build OS is
ubuntu_12.04,it can run up on the board.

but in ./external it can't be compiled. i want to build out gst-launch on
android, i can test it in android adb shell.

can u help me ? or support me modify the android.mk, it ll be build in
android. When I build ,the error is have not GLIB and Gstream-0.10 lib,but
in ubuntu,I have intall

the gstreamer-0.10 libs,and I can use gst-launch on my ubuntu server. But
how can I build it on android and run on the borad. Thx.





And the other method is use gstreamersdk, but when I build it,it also have
errors:
