What steps will reproduce the problem?
1.I recompile the x264 use more cpu follow this:
https://groups.google.com/forum/#!topic/android-ndk/_OHzzpyw29U
for android use corss-compile. After tested ./x264 on my android device,it 
works well (multicore works), the encode fps can get to 50, while use only one 
core,the fps is only about 25 ;
2.But when I replace libx264.lib in thirdparties/android/armv7-a/libx264.a with 
the one I compiled, I find there isn't any help except the 4 core(my android 
phone has 4 cores)are all in use, the video encode time 
(tinyDAV/src/codes/tdav_codec_h264.c ,function tdav_codec_h264_encode) 
avcodec_encode_video used isn't reduce any.That is to say the multi-core isn't 
work with doubango?
3.So anyone can help me, why multicore didn't work with doubango?

What is the expected output? What do you see instead?
