lavfi: create buffer reference in filters which need to access the ref later
Also add internal function ff_null_start_frame_keep_ref(). Fix crash when a following filter (e.g. settb) will unref the reference passed by start_frame(), and then the reference is accessed in end_frame() through inlink->cur_buf. |

lavfi: add bbox filter
Also add bbox.h and bbox.c files, based on the remove-logo filter by Robert Edele. These files are useful for sharing code with the pending removelogo port. |
