-Subject: [PATCH] VP8: Fix use-after-free in postproc.
-
-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.
