-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 My kernel is 3.13.7, as I have reported before, mfc encoder can't request buffer, I increase the mfc size in dts file from 0x800000 to 0x4000000, then it can request buffer now, but it can't enqueue the input(OUTPUT in v4l2 side) buffer which is just dequeued after stream has start. Here is the log of samsung demo, I don't get any information in dmesg root@kagami:~# ./mfc-encode -m /dev/video1 -c h264 mfc codec encoding example application Andrzej Hajda <a.hajda@xxxxxxxxxxx> Copyright 2012 Samsung Electronics Co., Ltd. 50.370398146:args.c:parse_args:187: codec: H264 50.386230729:mfc.c:mfc_create:87: MFC device /dev/video1 opened with fd=3 50.402226771:v4l_dev.c:v4l_req_bufs:116: Succesfully requested 16 buffers for device 3:0 50.402356979:func_dev.c:func_req_bufs:42: Succesfully requested 16 buffers for device -1:1 50.402523896:func_dev.c:func_enq_buf:113: Enqueued buffer 0/16 to -1:1 50.402677896:func_dev.c:func_enq_buf:113: Enqueued buffer 1/16 to -1:1 50.402819771:func_dev.c:func_enq_buf:113: Enqueued buffer 2/16 to -1:1 50.403051729:func_dev.c:func_enq_buf:113: Enqueued buffer 3/16 to -1:1 50.403199646:func_dev.c:func_enq_buf:113: Enqueued buffer 4/16 to -1:1 50.403604562:func_dev.c:func_enq_buf:113: Enqueued buffer 5/16 to -1:1 50.403880187:func_dev.c:func_enq_buf:113: Enqueued buffer 6/16 to -1:1 50.404194396:func_dev.c:func_enq_buf:113: Enqueued buffer 7/16 to -1:1 50.404580146:func_dev.c:func_enq_buf:113: Enqueued buffer 8/16 to -1:1 50.404951021:func_dev.c:func_enq_buf:113: Enqueued buffer 9/16 to -1:1 50.405400896:func_dev.c:func_enq_buf:113: Enqueued buffer 10/16 to -1:1 50.405554729:func_dev.c:func_enq_buf:113: Enqueued buffer 11/16 to -1:1 50.405721271:func_dev.c:func_enq_buf:113: Enqueued buffer 12/16 to -1:1 50.405791896:func_dev.c:func_enq_buf:113: Enqueued buffer 13/16 to -1:1 50.405933604:func_dev.c:func_enq_buf:113: Enqueued buffer 14/16 to -1:1 50.406003646:func_dev.c:func_enq_buf:113: Enqueued buffer 15/16 to -1:1 50.473507729:v4l_dev.c:v4l_req_bufs:116: Succesfully requested 4 buffers for device 3:1 50.473621146:func_dev.c:func_req_bufs:42: Succesfully requested 4 buffers for device 4:0 50.473815312:v4l_dev.c:v4l_enq_buf:211: Enqueued buffer 0/4 to 3:1 50.474005771:v4l_dev.c:v4l_enq_buf:211: Enqueued buffer 1/4 to 3:1 50.474252854:v4l_dev.c:v4l_enq_buf:211: Enqueued buffer 2/4 to 3:1 50.474754854:v4l_dev.c:v4l_enq_buf:211: Enqueued buffer 3/4 to 3:1 State [enq cnt/max]: [Off 0 0/0|Rdy 16 0/250] [Off 0 0/0|Off 4 0/0] [Off 0 0/0|Off 0 0/0] State [enq cnt/max]: [Off 0 0/0|Rdy 16 0/250] [Off 0 0/0|Off 4 0/0] [Off 0 0/0|Off 0 0/0] 50.476985521:func_dev.c:func_deq_buf:79: Dequeued buffer 0/16 from - -1:1 ret=25344 v4l_dev.c:v4l_enq_buf:207: error: Error 22 enq buffer 0/16 to 3:0 50.477464521:io_dev.c:process_chain:165: pair 0:1 ret=-1 I have tried [Linaro-mm-sig] [PATCH][RFC] mm: Don't put CMA pages on per-cpu lists but it doesn't have any effect and if I don't modify the size in dts it will failed in request buffer either. In the program wroten by myself(I have tested work in manufacturer's 3.5 kernel), it can't dequeue the OUPUT at all neither the second frame in CAPTURE(with V4L2_CID_MPEG_VIDEO_HEADER_MODE in 0), of course, there is not any frame in OUTPUT, it is impossible to get the the second frame in CAPTURE.
