Subject: [PATCH v3 0/7] media: mediatek: vcodec: fix v4l2_ctrl_request_complete fail
Date: Thu, 13 Jun 2024 15:55:25 +0800
Message-ID: <20240613075532.32128-1-yunfei.dong@mediatek.com>

v4l2_m2m_buf_done is called in lat work queue, v4l2_ctrl_request_complete
is called in core queue. The request status of output queue will be set to
MEDIA_REQUEST_STATE_COMPLETE when v4l2_m2m_buf_done is called, leading to
output queue request complete fail. Must move v4l2_ctrl_request_complete
in front of v4l2_m2m_buf_done.

Patch 1 setting request complete before buffer done
Patch 2 change flush decode from capture to output when stream off
Patch 3 flush decoder before remove all source buffer
Patch 4 using input information to get vb2 buffer
Patch 5 store source vb2 buffer
Patch 6 replace v4l2_m2m_next_src_buf with v4l2_m2m_src_buf_remove
Patch 7 remove media request checking

---
compared with v2:
- add patch 5/6/7 to fix decode again issue
- add fluster test result with mt8195 platform(same with no changed):
  1> ./fluster.py run -d GStreamer-VP8-V4L2SL-Gst1.0 -j1 -t 90
     VP8-TEST-VECTORS 59/61
  2> ./fluster.py run -d GStreamer-VP9-V4L2SL-Gst1.0 -j1 -t 90
     VP9-TEST-VECTORS 276/305
  3> ./fluster.py run -d GStreamer-AV1-V4L2SL-Gst1.0 -j1 -t 90
     AV1-TEST-VECTORS 237/239
  4> ./fluster.py run -d GStreamer-H.264-V4L2SL-Gst1.0 -j1 -t 90
     JVT-AVC_V1       95/135
  5> ./fluster.py run -d GStreamer-H.265-V4L2SL-Gst1.0 -j1 -t 90
     JCT-VC-HEVC_V1   142/147

compared with v1:
- add patch 2/3/4 to fix timing issue.
