ff_cuda_cuarray_elem_size()

static int ff_cuda_cuarray_elem_size ( CUarray_format  fmt )

Return the element size in bytes for a CUarray_format, or 0 for unknown.

Used to compute frame->linesize[] for CUarray frames (block-linear). Callers that need a fallback should treat a 0 return as an error.
