1. A video encoding method, performed by an encoding apparatus, comprising:
encoding a random access point picture,
encoding at least one of leading pictures or normal pictures associated with the random access point picture;
outputting a bitstream comprising information on the random access point picture, the leading pictures and the normal pictures based on the encoding, wherein the leading pictures precede the random access point picture in output order and the normal pictures follow the random access point picture in output order;
wherein the random access point picture is an instantaneous decoding refresh (IDR) picture or a clean random access (CRA) picture;
wherein the leading picture is not used as a reference picture for the normal picture,
wherein the leading pictures precede the normal pictures in decoding order,
wherein a leading picture associated with the CRA picture is not output when the random access point picture is the CRA picture and a random access happens to the CRA picture, and
wherein a leading picture associated with the IDR picture is decoded by using at least one of the IDR picture and another leading picture as a reference picture when the random access point picture is the IDR picture and the random access happens to the IDR picture.
