For drop due to large overshoot feature (in 1 pass CBR): add additional condition that current prediction error is larger than that of last encoded frame. This make the drop due to sudden overshoot more robust, and improves rate convergence for steady hard content. Change-Id: If20027d26b4dcd290e4f788ae8e2760d95b536a5

2018-12-14vp8: Fix potential use-after-free in mfqe.Jerome Jiang
Similar issue to 842265. The pointer in vp8 postproc refers to show_frame_mi which is only updated on show frame. However, when there is a no-show frame which also changes the size (thus new frame buffers allocated), show_frame_mi is not updated with new frame buffer memory. Change the pointer in postproc to mi which is always updated. BUG=913246 Change-Id: I5159ba7134a06db472c29a1d84b8d39bb60c7254
