The request will be marked to complete status when the buffer is set to done, then request object will be cleaned form media request. When v4l2_ctrl_request_complete() is later called, the control request detect that there is no controls in the request object. It then creates an empty control request object, but attaching an object to a completed request is not allowed. --- compared with v5: - fix comments for patch 3 - fix smatch error for patch 1 compared with v4: - re-write the commit message for cover-letter - change patch 2/3/4/5 commit message compared with v3: - fix flush decoder issue when userspace stream off capture queue firstly - fluster test result same with v3 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. --- Yunfei Dong (5): media: mediatek: vcodec: setting request complete before buffer done media: mediatek: vcodec: change flush decode order when stream off media: mediatek: vcodec: Get SRC buffer from bitstream instead of M2M media: mediatek: vcodec: store current vb2 buffer to decode again media: mediatek: vcodec: remove media request checking .../mediatek/vcodec/decoder/mtk_vcodec_dec.c | 44 +++++++-------- .../vcodec/decoder/mtk_vcodec_dec_drv.h | 4 +- .../vcodec/decoder/mtk_vcodec_dec_stateless.c | 53 ++++++++++++++----- .../vcodec/decoder/vdec/vdec_av1_req_lat_if.c | 28 ++++------ .../decoder/vdec/vdec_h264_req_multi_if.c | 4 +- .../decoder/vdec/vdec_hevc_req_multi_if.c | 4 +- .../vcodec/decoder/vdec/vdec_vp9_req_lat_if.c | 28 ++++------ .../mediatek/vcodec/decoder/vdec_msg_queue.h | 4 +- 8 files changed, 92 insertions(+), 77 deletions(-)
