From b6d7e8031c9c17462935329ca8b37f0da2f99da0 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Thu, 29 Apr 2021 16:48:13 +0200 Subject: [PATCH] media: uapi: mpeg2: Move reference buffer fields The forward and backwards references are specified per-picture and not per-slice. Move it to V4L2_CID_MPEG_VIDEO_MPEG2_PICTURE.
