Hey Yunfei,
given this new series by Hans:
https://patchwork.linuxtv.org/project/linux-media/list/?series=13427
we might actually be able to find a more performant solution of the
problem, I'll work on that a bit and give you feedback.
Regards,
Sebastian

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 order when stream off
Patch 3 flush decoder before stream off
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 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):
