when use libyami to test scv-t cbr mode, and set layer number as 4. base layer input bit rate as 800 , the output bitrate is more than 10% compared with input bitrate. Detail data can be found in attachment file.

The result depends on AVC encoder quality. Actually AVC encoder also has quality issue when encoding a similar base layer stream.
