I don't fully understand this change. Could you explain why the target bitrate
changes from 50 to 90?

[marpan, 2015/10/23 15:57:10]

resize logic was changed to allow for 3/4 resizing first (before going down to
1/2 if things are still bad), so for this test at 50k, 2 resize actions occur. 

Either needed to increase bitrate and keep 1 resize action (and also keep same
expected RC metric values), or keep the bitrate=50k and change some expected
values in RC metrics(line 749). Went back to the latter change now (as in
patch#3).
