Okay, i found the issue:

mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

is a bad idea in some pre-3 android version, this leads to an always 
invalid surface: holder.getSurface().isValid() is always false in the 
surfaceChanged() callback.

Well, removing this line now, video works, but although displaying, it 
is so slow/freezing that it is unusable. I tried also a vanilla VLC on 
old phones (with NO_FPU=1) and the result is the same almost frozen 
video, while Android's MediaPlayer displays the same video flawlessly.
Has this issue been considered already in armeabi no_fpu phones ?
Thanks,
- Ben
