From 2e2c3d6c0ef88ffac0d6b5079ee88cf8408f5f3b Mon Sep 17 00:00:00 2001 From: Nicolas Dufresne Date: Fri, 13 May 2022 22:29:03 +0200 Subject: media: h264: Use v4l2_h264_reference for reflist In preparation for adding field decoding support, convert the byte arrays for reflist into array of struct v4l2_h264_reference. That struct will allow us to mark which field of the reference picture is being referenced.
