x264enc on android: very slow.

[Haiming Wang]

Hi Tonu, 
  Thank you very much for sharing this information . Does your full hd video means 720p video?
 Will your change be submitted to gstreamer trunk?

Huge difference between hardware or software. The API for codecs starts from Android 4.1. http://developer.android.com/reference/android/media/MediaCodec.html

I see some software encoder running on Android, and the frame rate can reach 15 fps, and the performance is quite acceptable.  I want to know if there are some settings for x264enc, which can improve the performance.
