Support of base layer of a different codec in multi-layer video coding
An apparatus for coding video information according to certain aspects includes a memory and a processor. The memory unit is configured to store video information associated with an enhancement layer (EL) and a corresponding reference layer (RL). The processor is configured to: code an EL picture in a current access unit (AU), the EL coded using a first standard that is different from a second standard that is used to code the RL, wherein the coding of the EL picture is based on information associated with a RL picture in the current access unit, the information associated with the RL picture provided by an external means and consisting of: (1) decoded sample values of the RL picture; (2) a representation format of the RL picture; and (3) an indication of whether the RL picture is an instantaneous decoding refresh (IDR) picture.
