From 9f8b333308dcb6af321526a54612cfaa7999a995 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 18 Jul 2016 08:00:20 -0300 Subject: [media] vim2m: copy the other colorspace-related fields as well The xfer_func, ycbcr_enc and quantization fields should also be copied from output to capture format. Since this driver serves as example code it is important that this is handled correctly.
