Standard interlace handling: * If we have interlace-mode=interleaved and the field order, we just set it when creating the session * If we have interlace-mode=(interleaved|mixed) and no field order, we set the field order on the first buffer The encoder session does not support changing the FieldDetail after it has started encoding frames, so we cannot support mixed streams correctly.
