From: Mythri P K mythr...@ti.com
With AVI infoframe various parameters of video stream such as
aspect ratio, quantization range, videocode etc will be indicated
from source to sink.Thus AVI information needs to be set/accessed
by the middle ware based on the video content.
Thus this parameter is now moved to the ip_data structure.
