[PATCH v3 0/7] media: mediatek: vcodec: fix v4l2_ctrl_request_complete fail

From: Yunfei Dong
Date: Thu Jun 13 2024 - 03:56:08 EST


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
