fc0be57f66 plane predicted non-interlacd rgb decodeing fix

d925c516e4 huffyuv writes to AVCodecContext.stats_out only once every 32 frames, 
presumably to reduce the size of the log file.
However, it doesn't clear stats_out on the other 31 out of 32 frames.
So the application (ffmpeg and mencoder) writes each stat line 32 times.
