di: when src size change, post ready size not right [1/1]

PD#OTT-2650

Problem:
Play local video, when source window size change,
flashing occur. about two frame is not right

Solution:
There have a bug when source window size change, current
frame width was copied to post ready frame. so every
frame backup width saved in to current frame private buffer.

Verify:
TL1
