New description:

 When watching videos that are resized there is a green line along the
 botton and right of the picture.

 The green line only occurs if it is using texture format YV12. There are
 two texture formats used for most systems - YV12 and UYVY. The logic for
 choosing which to use is rather obscure. It is choosing UYVY on regular
 Linux and choosing YV12 on Android. Testing shows that both formats work
 for Linux as well as for Android, but YV12 is causing the green line on
 Android.

 Changing to use UYVY on Android solves the problem in most cases. However,
 watching interlaced SD content shows the problem again at the bottom of
 the screen, even using UYVY.

 There seems to be a problem with resizing and deinterlacing.
