Stefano Sabatini	6b55aab01a	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.	2012-04-27 21:38:13 +02:00
