Hi Kim,

Display link does not support composite buffer that sync link outputs. so we cannot put sync link before display link.
Why exactly you want to put sync before display?

Hi Brijesh,

I'm trying to transfer RTOS usecase to HLOS.
In case of vision_sdk\apps\src\rtos\usecases\iss_mult_capture_isp_simcop_stereo_tda3xx, the link flow is below.

UseCase: chains_issMultCaptIspSimcop_Stereo


IssCapture -> IssM2mIsp -> IssM2mResizer_Capture -> Select_Capture -> IssM2mSimcop -> Merge_Simcop -> Dup_Simcop

Select_Capture -> Merge_Simcop


Dup_Simcop -> Sync_Org -> Alg_DmaSwMs -> Display_Org

Dup_Simcop -> Sync_CensusIn -> Dup_CensusIn -> Alg_Census (EVE1) -> Alg_DisparityHamDist (EVE1) -> Merge_StereoOut -> Alg_StereoPostProcess (DSP1) -> Display_Disparity

Dup_CensusIn->Merge_StereoOut


IssM2mIsp -> Alg_IssAewb

GrpxSrc -> Display_Grp

For this case, the link flow (Dup_Simcop -> Sync_Org -> Alg_DmaSwMs -> Display_Org )is specified.
I'm trying to add sync link and Alg_DmaSwMs link.

Then, In order to use Sync link, should I add Alg_DmaSwMs cause Display link does not support composite buffers?
I read the VisionSDK_SW_Architecture.pdf, but the sync link does not be explained detail.


Thanks,
Heechang

Hi Kim,

Yes, you could add sync link and dma sw ms to display all four channels in a single frame. But please note that DMA sw ms internally uses same ISP for the resizing operation. So ISP may not run in real time.

Rgds,
Brijesh

Dear Brijesh,

Thanks, your reply.
I have a question.
Then, ISSM2mIsp -> Select_Capture -> Merge_Simcop->Dup_Simcop->Alg_DMASwMs->Display_Video case will does not matter to display?
I just will remove Sync link.

Thanks
Best regards,
Heechang

Hi Kim,

You require sync link before dma sw ms, this is to make sure that all four channels, which you want to put in a single frame, are available at the same time to the dma sw ms.

Rgds,
Brijesh

Hi Brijesh,

When I set the link flow like
IssCapture -> IssM2mIsp -> IssM2mResizer_Capture -> Select_Capture -> IssM2mSimcop -> Merge_Simcop -> Dup_Simcop
Select_Capture -> Merge_Simcop
Dup_Simcop -> Sync_Org -> Alg_DmaSwMs -> Display_Org
,
the monitor is green by HDMI.

But, When I remove the two links which are Sync_Org and Alg_DmaSwMs, the capture frame is shown good.

What is problem?

Heechang

Hi Kim,

How many input cameras do you have?

Rgds,
Brijesh

Hi Brijesh

I have two cameras input and connected these to EVM.
Later I will use 3 cameras.
Once I'm using 2 cameras input now.

Heechang

Hi Kim,

Have you changed DMA SW ms parameters to correct mosaic them? Also what is your sync parameters? Is your sync delta and threshold set correctly?
Depending on your chain and modules used in the chain, you need to set sync delta and threshold..

Rgds,
Brijesh

Hi Brijesh,

I used DMA SW ms parameters same with another usecase(vision_sdk\apps\src\rtos\usecases\avbrx_dec_display_avbtx). And numChannel is 2 and displayWidth and displayHeight set by 1920 and 1080.

The sync function parameters are #define SYNC_DELTA_IN_MSEC and #define SYNC_DROP_THRESHOLD_IN_MSEC (33).

Best regards,
Heechang

Hi Kim,

Typically we keep threshold = delta x 2.
Can you increase depta to 50ms and try it out?

Rgds,
Brijesh

Hi Brijesh,

I changed the SYNC_DELTA_IN_MSEC value to 50 but the result is same(SYNC_DROP_THRESHOLD_IN_MSEC is 33).
I attached my code.

Something is wrong?

Regards,
Heechang

Hi Kim,
Since it works without sync, it is clear that sync is dropping frames. Now sync will drop frames only if time stamp from both the frames are more than the delta/threshold specified. Please check first by setting delta to 1000 and see if it outputs something.

Rgds,
Brijesh

Hi Brijesh,

I changed the parameter SYNC_DROP_THRESHOLD_IN_MSEC 33 to 100 (delat is 50) as you said.
The green screen is gone.
But, just statistcs data screen is shown like TI logo and core sharing.

Should I adjust the sync values?

Regards,
Heechang

Hi Brijesh,

Could you explain regarding SYNC_DROP_THRESHOLD_IN_MSEC and SYNC_DELTA_IN_MSEC?
How should I set the values?

Regards,
Heechang

Hi Kim,

Since you are capturing two channels at 30fps, their timestamp should be at max 33ms apart. This is sync delta. Sync link will try to synchronize the frame, whose time stamp is within sync delta.
Now if the frame from cam0 goes through different chain than the frame from cam1, we need to include latency for the cam0 also in the sync delta. So lets say Simcop takes around 30ms, the delta between cam0 and cam1 frame could be around 63ms. If the two frame's timestamp are withing 63ms, they will be merged and sent out as a composite frame.
But if that does not match, it will wait for the threshold amount of time to synchronize the frame. if it does not receive frame whose timestamp is within sync delta withing threshold time, then it will drop the frame.

If you set delta to 1000, it will match any two frames and send them out.

Brijesh

Hi Brijesh,

When I merge Sync and Alg_DMASwMs links, the System_linkCreate of the Display link is failed.

Hi Kim,

Can you check your output resolution from SWMS? You could vps_print outWidth/outHeight after below statements.

220 pPrm->maxOutBufWidth = outWidth;
221 pPrm->maxOutBufHeight = outHeight;

Also what is your display size? Are you displaying it over smaller LCD? Please note that display cannot upscale more than 8x. It seems outwidth/outheight is incorrect as per the display resolution.

Rgds,
Brijesh

Hi Brijesh,

pPrm->maxOutBufWidth = 1920;
pPrm->maxOutBufHeight = 1080;

My display size is 1920*1080.

Regards,
Heechang

Hi Kim,

Can you put breakpoint in the display link and check what it is trying to set as input frame size?
It seems it is wrongly configuring input frame size.. Then you could back trace to check where the incorrect frame size is set.

Rgds,
Brijesh

Hi Brijesh,

I don't have emulator so I just insert log to code.

Hi Brijesh,

I found the reason why the log is shown which is "Upscaling of greater than 8x is not supported".
I checked the function of "Int32 DisplayLink_drvDisplayCreate(DisplayLink_Obj *pObj)"
The parameters are as below.
pObj->createArgs.rtParams.tarWidth : 1920
pObj->createArgs.rtParams.tarHeight : 1080
dssPrms->inFmt.width = pInChInfo->width : 0
dssPrms->inFmt.height = pInChInfo->height :0

In function of VpsCore_dssValidateDssParams(),
It is checked like below.

1426 /* Scaling ratio check */
1427 if (((pathCfg->inFmt.height * 8) <
1428 (pathCfg->tarHeight)) ||
1429 ((pathCfg->inFmt.width * 8) < (pathCfg->tarWidth)))
1430 {
1431 GT_0trace(
1432 VpsDssCoreTrace, GT_ERR,
1433 "Upscaling of greater than 8x is not supported \r\n");
1434 retVal = BSP_EINVALID_PARAMS;
1435 }

I have a question.
Before create the link, set the parameters of the "DisplayLink_CreateParams".

The pInChInfo is System_LinkChInfo.
But, I don't set the parameters related with System_LinkChInfo.

When the parameters of the System_LinkChInfo is set?

Best regards,
Heechang

Hi Brijesh,

If I inserted Alg_DmaSwMs link, dssPrms->inFmt.width and dssPrms->inFmt.height are zero.
But, I think that the Alg_DmaSwMs does not set the dssPrms.

Hi Brijesh,

I resolved this issue changing the linkID.

73 Void chains_issIspSimcop_Display_SetLinkId(chains_issIspSimcop_DisplayObj *pObj){
74 pObj->IssCaptureLinkID = SYSTEM_LINK_ID_ISSCAPTURE_0;
75 pObj->IssM2mIspLinkID = SYSTEM_LINK_ID_ISSM2MISP_0;
76 pObj->Alg_IssAewbLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_ALG_1); //origianlly SYSTEM_LINK_ID_ALG_0
77 pObj->IssM2mSimcopLinkID = SYSTEM_LINK_ID_ISSM2MSIMCOP_0;
78 pObj->Select_CaptureLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_SELECT_0);
79 pObj->Merge_SimcopLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_MERGE_0);
80 pObj->Dup_SimcopLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_DUP_0);
81 pObj->Sync_OrgLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_SYNC_0);
82 pObj->Alg_DmaSwMsLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_ALG_0);
83 pObj->Display_VideoLinkID = SYSTEM_LINK_ID_DISPLAY_0;
84 pObj->GrpxSrcLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_GRPX_SRC_0);
85 pObj->Display_GrpxLinkID = SYSTEM_LINK_ID_DISPLAY_1;
86 }

I have two question.

First,
This code is generated by code generation tools.
The Alg_IssAewbLinkID and Alg_DmaSwMsLinkID are same link ID(SYSTEM_LINK_ID_ALG_0).
Do I change this link id value?

Second,
The screen shows statistics data and TI logo with black screen.
If I remove Sync and Alg_DmaSwMs link, the camera input screen is shown.
I don't know that it is normal or not.

Thank you very much.
Best regards,
Heechang

Hi Kim,

That's great.

If you are running both of these algos on the same core, then the link id must be different, cannot use ALG_0 for both AEWB and DMA SWMS.  Can you change to ALG_1 for DMA SWMS.

This is still not correct, it means sync is still dropping frames. can you check sync parameters? can you share print stats by pressing 'p' console?

Rgds,

this means that frames are all dropped?

BR,
Heechang

Hi Kim,

Yes, Sync is dropping all frames, if you see, it gets two channels are 24 and 26 fps rate, but it looks like it is dropping all of them. It looks like your chain takes longer.
Are you running in debug build? Please run in release build.
In addition can you check both the channels paths and see the differences and latency that can be introduced by these two chains/paths?
Also why is there a fps drop? Capture is 30fps, but at sync, one of them is 24fps and other is 26fps??

Where can I found the build option of the release or debug?

Thanks

Hi Brijesh,

I ran the app with "release" build option.
But, the result is same.

The reason why the frame rate from 30 to 24 is passed by ISSM2MSIMCOP link.
If I adjust the sync delta and threshold parameters, the drop frame can be resolved?

Thanks

If I modified the sync parameters(delta=10, threshold=20), the SIMCOP link does not drop the frame rate.

Regards,
Heechang

Hi Kim,

ok, the simcop link was dropping the frames due to output buffer unavailability. The output buffer were held in the sync link, due to high threshold set. Can you check simcop number of output buffers? Atleast three buffers are required in the simcop output buffer.
Also please try tuning sync delta and threshold to for the sync to start outputting buffers..

Rgds,
Brijesh

Hi brijesh,

pUcObj->IssM2mIspPrm.channelParams[i].numBuffersPerCh = 4; (i=1, 2 for 2 chnnels)
I used 4 output buffers for simcop.

To resolve this problem, should I tune sync parameters?

Rgds,
Heechang

can you also check number of output buffers in simcop?

Rgds,
Brijesh

Hi Brijesh,

The Simcop output buffers set 4 each channel.

Regards,
Heechang

Hi Brijesh,

My usecase in HLOS is below.

ISS capture -> ISSM2mIsp -> Alg_IssAewb
ISSM2mIsp -> Select_Capture -> Merge_Simcop->Dup_Simcop->Sync->Alg_DmaSwMs->Display_Video
Select_Capture->ISSM2mSimcop->Merge_Simcop

GrpxSrc -> DisplayGrpx

This usecase can run in HLOS?

I'm tuning sync parameters but sync link dropped the frames all.
I use VSDK v3.4.

I'm using the code generation tool for xxxxx_priv.h and xxxx_priv.c.
I think that I just set the parameters.

If I remove the sync and alg_dmaswms, the camera screen is shown well.
So, I think that the parameters set are not problem except Sync parameters.

But, the Sync link parameters set by only two parameters which are delta and threshold.

I tried many case of delta and threshold but the sync dropped the frames.

I want to resolve this issue.

Thank you for your effort.

Best regards,
Heechang

Hi Brijesh,

I cannot find the IssM2mSimcop Link in HLOS usecases.
The IssM2mSimcop Link can not be used in HLOS?

Rgds,
Heechang

Hi Brijesh,

Except for iss_capture_isp_display, I cannot find Simcop example.
I set the simcop parameters like iss_capture_isp_display.

Regards,
Heechang

Hi Kim,

Can you please share your usecase file (text) again? Let me check and get  back to you.

Rgds,

Brijesh

Is this the usecase that you are using ?

ISS capture -> ISSM2mIsp -> Alg_IssAewb
ISSM2mIsp -> Select_Capture -> Merge_Simcop->Dup_Simcop->Sync->Alg_DmaSwMs->Display_Video
Select_Capture->ISSM2mSimcop->Merge_Simcop

Why do you have select link after ISP link? Does it mean you want to do simcop only for one of the channel only? After Merge why is there a dup link? could you please explain what is your usecase?

Rgds,
Brijesh

Hi Brijesh,

1. Why do you have select link after ISP link? Does it mean you want to do simcop only for one of the channel only?
My purpose is using usecase of vision_sdk/apps/src/rtos/usecases/iss_mult_capture_isp_simcop_stereo_tda3xx in RTOS.

In vision_sdk/apps/src/rtos/usecases/iss_mult_capture_isp_simcop_stereo_tda3xx,
the usecase is IssCapture -> IssM2mIsp -> IssM2mResizer_Capture -> Select_Capture.
But, I build for Linux so I remove the IssM2mResizer cause it is not build in HLOS.

Now,
My usecase is
ISS capture -> ISSM2mIsp -> Alg_IssAewb
ISSM2mIsp -> Select_Capture -> Merge_Simcop->Dup_Simcop->Sync->Alg_DmaSwMs->Display_Video
Select_Capture->ISSM2mSimcop->Merge_Simcop

After above usecase is done,
I will do usecase like path vision_sdk/apps/src/rtos/usecases/iss_mult_capture_isp_simcop_stereo_tda3xx .

2. After Merge why is there a dup link?
I will add the Alg_Census link in EVE after IPU link is done.
So, I set the parameter of pObj->Dup_SimcopPrm).numOutQue = 1; (after IPU runs well, I will set from 1 to 2)


Thanks,
Rgds,
Heechang

ok, i see.
For the time being, can you disable/bypass simcop and see if second path reaches to the sync link in time?
I am assuming that you have two input camera for this usecase.

Rgds,
Brijesh

Hi Brijesh,

I made the usecase as below.
IssCapture -> IssM2mIsp -> Select_Capture -> Merge_Simcop -> Dup_Simcop
Dup_Simcop -> Sync_Org -> Alg_DmaSwMs -> Display_Org
IssM2mIsp -> Alg_IssAewb
GrpxSrc -> Display_Grpx

If I run the application, then the error log is shown.

[HOST] [IPU2 ] 232.639053 s: SYSTEM: NOTIFY: Send Event to [IPU2][9] failed !!! (status = -14)
[HOST] [IPU2 ] 232.639175 s: Assertion @ Line: 232 in system_ipc_bios_ipc.c: (Bool)FALSE : failed !!!

I set the select link parameters as below.

pPrm->outQueChInfo[0].outQueId = 0;
pPrm->outQueChInfo[0].numOutCh = 1;
pPrm->outQueChInfo[0].inChNum[0] = 0;

When I use ISSM2mSimcop, I disabled resizerB.
Is it related with this Sync Link?

371 pPrm->outQueChInfo[1].inChNum[0] = 2;
372 pPrm->outQueChInfo[1].inChNum[1] = 3;
373 #endif

I have two cameras that input to "Select Link" each ch 0 and ch 1, right?
[1 input -> Select Link -> 2 output]
Cam0 (inChNum[0]=0) -> Select Link -> ISSM2mSimcop Link (outQueChInfo[0])
Cam1 (inChNum[0]=1) -> Select Link -> ISSM2mSimcop Link (outQueChInfo[1])

Now,
I can see the camera input screen with cam0 and cam1.

If you don't help me, I cannot resolve this issue.
Thank you very much!!

Thank you!!

p.s. I will set the EVE and DSP link to achieve my final purpose(vision_sdk/apps/src/rtos/usecases/iss_mult_capture_isp_simcop_stereo_tda3xx in HLOS)
Please help me, again if I have a problem.

Hi Brijesh,

I added other links like below.(usecase)

IssCapture -> IssM2mIsp -> Select_Capture -> IssM2mSimcop -> Merge_Simcop -> Dup_Simcop

Select_Capture -> Merge_Simcop
Dup_Simcop -> Sync_Org -> Alg_DmaSwMs -> Display_Org

Dup_Simcop -> Sync_CensusIn -> Dup_CensusIn -> Alg_Census (EVE1) -> Alg_DisparityHamDist (EVE1) -> Merge_StereoOut -> Alg_StereoPostProcess (DSP1) -> Display_Disparity
Dup_CensusIn->Merge_StereoOut
IssM2mIsp -> Alg_IssAewb
GrpxSrc -> Display_Grpx


When the usecase create the StereoPostProcess link, the error is shown.
I used the parameters the function of ChainsCommon_TDA3x_Stereo_SetPrms() which path is /vision_sdk/apps/src/rtos/usecases/common/chains_common_stereo.c

But, the error returns that the handle is null as below.
The path of the function is vision_sdk/apps/src/rtos/alg_plugins/stereo_postprocessing/stereoPostProcessLink_algPlugin.c.
(line 421: pStereoPostProcessObj->handle = AlgIvision_create(&STEREOVISION_TI_VISION_FXNS, (IALG_Params *)(pAlgCreateParams));)

It looks like the structure does not be allocated but I think that I set the parameters related to "StereoPostProcessing".

Thanks

Hi Brijesh,

I debugged the code.
when "AlgIvision_create" is called, the malloc is run.
This malloc function returns address and the fxns->ialg.algAlloc is run.
But, the status value is -1023 after fxns->ialg.algAlloc is run.
(AlgIvision_create_useLinkMem())

What is problem?

Rgds,
