Subject: [PATCH v5 2/5] [media] videodev2: Add V4L2_BUF_FLAG_LAST
Date: Mon, 20 Apr 2015 10:28:21 +0200	[thread overview]
Message-ID: <1429518504-14880-3-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1429518504-14880-1-git-send-email-p.zabel@pengutronix.de>

From: Peter Seiderer <ps.report@gmx.net>

This v4l2_buffer flag can be used by drivers to mark a capture buffer
as the last generated buffer, for example after a V4L2_DEC_CMD_STOP
command was issued.
