Subject: [PATCH 1/2] media: hevc: Add segment address field
Date: Sun, 6 Jun 2021 10:23:13 +0200 [thread overview]
Message-ID: <20210606082314.454193-2-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20210606082314.454193-1-jernej.skrabec@gmail.com>
If HEVC frame consists of multiple slices, segment address has to be
known in order to properly decode it.
Add segment address field to slice parameters.
