Hello, 
I'm doing an experiment with Android tutorial 2: A running pipeline.
Basically this tutorial explains about basic gstreamer pipeline with android
device. I have changed pipeline data->pipeline = gst_parse_launch("audiotestsrc
! audioconvert ! audioresample ! autoaudiosink", &error); to 
data->pipeline = gst_parse_launch("videotestsrc num-buffers=2000 ! x264enc
byte-stream =TRUE !filesink location=/mnt/sdcard/TestRelease.264", &error);  
Now I run the android-tutorial-2 with ant debug and ant release. ant debug
takes around 17 seconds to encode and ant release takes around 32 seconds. 

Attached modified jni and java file.(UI of android tutorial 2 is disabled in
java file)
Environment:
Android version: 4.4.2
Device: Samsung S4
