To match the enumerated media devices, each registered pipeline handler is used in no specific order. It is a limitation when several pipelines can match the devices, and user has to select a specific pipeline. For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is created to give the option to define an ordered list of pipelines to match on. LIBCAMERA_PIPELINES_MATCH_LIST="<name1>[,<name2>[,<name3>...]]]" Example: LIBCAMERA_PIPELINES_MATCH_LIST="rkisp1,simple" Signed-off-by: Julien Vuillaumier <julien.vuillaumier@nxp.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
