Video coding may include identifying an input frame from an input video stream, generating, by a processor, an output bitstream by encoding the input frame, wherein encoding the input frame includes dividing the input frame into at least a first contiguous area of the input frame and a second contiguous area of the input frame, generating first encoded data by encoding the first contiguous area of the input frame, generating second encoded data by encoding the second contiguous area of the input frame, wherein encoding the second contiguous area of the input frame is performed independently of encoding the first contiguous area of the input frame, and including the first encoded data and the second encoded data in the output bitstream, and outputting the output bitstream.
