Problem:
When playing 1280x128 video under normal screen mode, the aspect ratio from
decodec is not accurate enough by multipling 0x100. (128x256/1280=25.6).
Dropping 0.6 will cause height losing 9 lines.
Solution:
Using new interface to pass real ar width and height following steps:
1.Set old ar variable to 0x3ff as a trigger flag.
2.set the original ar value into sar_width and sar_height of vframe
