Don't set profiles if no settings are specified. Apply all settings before starting a pipeline as the mode can switch without being restarted and incompatible video recording settings can prevent the pipeline starting even in image capture mode. Set audio encoding settings and encoder profiles if they are supplied. Change-Id: I06febf977c2cae306383f9dbaae0f81f531b4757 Reviewed-by: Yoann Lopes <yoann.lopes@digia.com>
