The code currently use cur_buf as the target of the copy, but cur_buf can be cleared by the filter if it has given the reference away or stored it elsewhere as soon as start_frame. The code still relies on the fact that the reference is not destroyed until end_frame. All filters currently follow that condition. An av_assert1() is added to check it; it should at least cause very visible errors in valgrind.
