avcodec/zmbvenc: Avoid copying packet data, allow user-supplied buffers Here the packet size is known before allocating the packet because the encoder itself works with an internal buffer, so one can use this information to avoid the implicit use of another intermediate buffer for the packet data; one can also switch to ff_get_encode_buffer() and directly use user-supplied buffers.
