Ahmet Inan eb7a494fe4 update rendering mode and activity title from decoder 2014-12-06 14:10:23 +01:00
Ahmet Inan 5c0dd886ab oops: fix double swap mistake of u & v and r & b 
in robot36 v is on even lines and u is on odd lines
in robot72 v comes first, then u

still need to investigate why there is a discrepancy between renderscript rgba and java bitmap rgba
