From 3949c6727fb8e4418c73108453c3c512b962d6f4 Mon Sep 17 00:00:00 2001
From: Dikshita Agarwal <quic_dikshita@quicinc.com>
Date: Fri, 7 Feb 2025 13:25:03 +0530
Subject: [PATCH] media: iris: add support for drain sequence
handle the V4L2_DEC_CMD_STOP by initiating a drain sequence on the
firmware. Process and decode all OUTPUT buffers, that are queued by the
client, before the VIDIOC_DECODER_CMD() was issued and mark the last
buffer with the V4L2_BUF_FLAG_LAST flag. The decoder is stopped, after
processing the last buffer.
Resume the decoder when one of these operations are issued by the client:
- V4L2_DEC_CMD_START
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE queue
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the OUTPUT queue
Add the handling to resume decoding when client issues
V4L2_DEC_CMD_START to resume decoding after a source change is detected.
