Browse Source 
PD#TV-3062

Problem:
When switching channels, Hisense platform needs hold video,
and the timming obtained at this time is wrong

Solution:
because we have add hold video function, so get width and
height interface give the last video frame width and height,
and so on change the video

Verify:
