This causes a division by\nzero when calculating num_dpb_buffer in H264 and H264 Perf decode\npaths.\n\nAdd validation to reject frames with width < 16 or height < 16\nbefore performing any calculations that depend on these values.\n\nV2: Format change - move up all vaiable definitions.\nV3: Use warn_once to avoid spam.\n\n(cherry picked from commit
