Reference pictures can be created to assist with video decoding. For example, a method for decoding video can comprise receiving an encoded video bit stream, determining that a reference picture is needed, and creating and inserting the reference picture into the encoded video bit stream. A method for decoding video can also comprise receiving an encoded video bit stream, performing bit stream parsing, determining that a reference picture is needed, selecting a representation level for the reference picture, and conveying data for the selected reference picture to a hardware accelerated graphics processing unit. Various video operations, such as creating reference pictures and related information, can be performed by central processing units, while other video decoding operations can be performed by graphics processing units.
