msdk: Set 16 bit alignment for width

Browse source 
According to MediaSDK specification,
Width must be a multiple of 16 and Height must be a multiple
of 16 for progressive frame sequence and a multiple of 32 otherwise.

This patch sets a 16 bit alignment for width and 32 bit alignment
for height as default.
