Comment (by gb):

 The new code generates extra DELAYED_PIC_REF, thus making code like if
 (pic->reference != PICT_FRAME) to check for something that is not a frame
 (i.e. top or bottom field) to fail. I have a patch at the VA-API level as
 I am not able to check why h264.c changes operate that way now.

 i.e. even in non-VAAPI case, h264 code that uses the FIELD_PICTURE macro
 may not get what it expected in the older code.
