Subject: [PATCH AUTOSEL 5.2 153/249] media: coda: increment sequence offset for the last returned frame
Date: Mon, 15 Jul 2019 09:45:18 -0400 [thread overview]
Message-ID: <20190715134655.4076-153-sashal@kernel.org> (raw)
In-Reply-To: <20190715134655.4076-1-sashal@kernel.org>
From: Philipp Zabel <p.zabel@pengutronix.de>
[ Upstream commit b3b7d96817cdb8b6fc353867705275dce8f41ccc ]
If no more frames are decoded in bitstream end mode, and a previously
decoded frame has been returned, the firmware still increments the frame
number. To avoid a sequence number mismatch after decoder restart,
increment the sequence_offset correction parameter.
