Log for execution of tutorial 3 on Android Emulator (Api9) using GStreamer 0.10

Hey all.

I am a getting to know GStreamer. I was trying to develop a simple Android
application that would receive a network stream generated on Desktop pc. I got
stuck in displaying simple video (e.g. videotestsrc) on some of my Android
devices and I have no clue where to go next.

First the description of my setup. For development I am using Nexus 10 (Android
4.3, API 18), Android emulators (different API's, tested on API's 9, 10, 16,
17) and a phone LG-P990 (Android 2.3.4, API 10). I develop on Ubuntu 13.04 (64
bit) and I am using Android NDK r9 (newest one). I was trying to run tutorial 3
from the website
(http://docs.gstreamer.com/display/GstSDK/Android+tutorial+3%3A+Video) using
two GStreamer SDK's:
- GStreamer SDK 2013.6 (Congo, avalible at
http://cdn.gstreamer.com/android/arm/gstreamer-sdk-android-arm-debug-2013.6.tar.bz2)
- GStreamer 1.2 (newest one, avalible at
http://gstreamer.freedesktop.org/data/pkg/android/1.2.0/gstreamer-1.0-android-arm-1.2.0-debug.tar.bz2)

Of course, running tutorial 3 using GStreamer 1.2 required some minor changes
in code:
- Android.mk:
        change GSTREAMER_SDK_ROOT to GSTREAMER_ROOT, so that it fits the
variable defined at gstreamer-1.0.mk
        change gstreamer.mk to gstreamer-1.0.mk and gstreamer-video-0.10 to
gstreamer-video-1.0 (and also remove interfaces)
- tutorial-3.c
        change #include <gst/interfaces/xoverlay.h> to #include
<gst/video/videooverlay.h>
        change all occurences of "x_overlay" string to "video_overlay"
        change ffmpegcolorspace to videoconvert

Taking into consideration those changes, I was able to run demos on LG-P990
phone (Android 2.3.4), but I was not able to make it work neither on Nexus 10
nor any of emulators. I get different errors from Nexus and from emulators, but
I feel the origin of those errors is the same.

>From what I inferred, the problem is connected with creating the surface to
display video. In both cases (emulator and Nexus 10) the error is generated
after invoking nativePause() in Tutorial3.java - line 108 (which invokes
gst_native_pause of tutorial-3.c line 247, where gst_element_set_state
(data->pipeline, GST_STATE_PAUSED) function is invoked).

I attach a log files, with a setting gst_debug_set_threshold_for_name("*egl*",
5).
