I'm using Kodi on my LG 47GA6400, which has a display of 1920x1080 resolution and is equipped with Android 4.2.2 on Eden CPU.

I noticed if I turned on MediaCodec accelerating, the video frame is stretched with black band on top and bottom of the screen, i.e., it is not stretched as a 16:9 picture although the screen is of true 16:9 aspect ratio. So I have to manually set aspect ratio each time when playing a new 720P video.

I tried Kodi from 14.2 all through latest 15.0 beta 2, they all have the same issue. The log looks like:

When MediaCode is off, the log looks like:

Note that there is no line like 'Crop rect is 1280 x 720" when MediaCodec is on

Any ideas?
