Subject: [PATCH v10 2/9] media: hevc: Add decode params control
Date: Tue, 20 Apr 2021 14:10:39 +0200
Message-ID: <20210420121046.181889-3-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210420121046.181889-1-benjamin.gaignard@collabora.com>

Add decode params control and the associated structure to group
all the information that are needed to decode a reference frame as
is described in ITU-T Rec. H.265 section "8.3.2 Decoding process
for reference picture set".

Adapt Cedrus driver to these changes.
