From aa4444063505983c5971bc8fb832385dfba16b41 Mon Sep 17 00:00:00 2001 From: Mats Randgaard Date: Thu, 16 Dec 2010 12:17:42 -0300 Subject: [media] vpif: Consolidate formats from capture and display - The ch_params tables in vpif_capture.c and vpif_display.c are moved to a common table in vpif.c. Then it is easier to maintain the table. - The field "fps" is removed from the struct vpif_channel_config_params because it is not used.
