Linux/DRA72XEVM: NullSrc + Decode + Mosaic + Display support

Hi Rajesh,

You can refer to usecase: PROCESSOR_SDK_VISION_03_05_00_00\vision_sdk\apps\src\rtos\usecases\lvds_vip_multi_cam_view.

Hi Rishabh,

Thanks for your quick reply.

In this usecase, instead of use capture src Can I use NullSource (A15) -> Decode -> VPE -> Dup -> Sync -> Alg_VpeSwMs -> Display.

It should work ?

Kindly suggest me !

Hi Rishabh,

Thanks for your reply.

I didn't start same topic twice. You sent URL is wrong.

For linux configuration, UC_lvds_vip_multi_cam_view_sgx_display usecase there is no Mosaic view support.

UseCase: chains_lvdsVipMultiCam_SgxDisplay^M
^M
Capture -> Sync (A15) -> SgxFrmcpy (A15)

// display on m4
Sync -> SgxFrmcpy

//
SgxFrmcpy -> Display_M4 (IPU1_0)
//
// Graphics overlay display
//
GrpxSrc -> Display_Grpx


Kindly suggest !!!

Hi Rajesh,

The URL is correct. "." got appended to the link.

Hi Rishabh,

Thanks for your reply.

Without generating the usecase using the tool, Can I modify the existing usecase source (adding NULLSRC and removing capture params etc..,) it should work ???

Kindly suggest me !!!

Regards,

Rajesh Kannan S

Hi Rajesh,

Modification will be prone to errors.
I would suggest you to generate a new use case rather than modifying one.

Rishabh

Hi Rishabh,

Thanks for your reply.

I could n't able to create new usecase by using vsdk_linux.out

Binary file I have taken from this location :- vision_sdk/apps/tools/vision_sdk_usecase_gen/bin
./vsdk_linux.out: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./vsdk_linux.out)

Could you guide to solve this issue !!!

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

Hi Rishabh,

Thanks for your reply.

I was on vacation. Back to work mode.

I could n't able to create usecase file.
./vsdk_linux.out: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by ./vsdk_linux.out)

I'm debugging this issue !!!

Hi Rajesh,

As I stated previously you should install the dependencies. You can refer to Linux user guide.

Regards,
Rishabh

Hi Rishabh,

Thanks for your reply.
I know that, as per your guidance I'm following the Linuxuserguide.
For Ubuntu14.04 (64 bit) I have tried to install, but I got this errors !!!

E: Unable to locate package uname
E: Unable to locate package mkimage

Debugging this issue !!!

Hi Rishabh,

As per Linux Userguide 2.2 I have installed all the packages individually. All are up to date it's updated.

Till I'm facing the issue `GLIBCXX_3.4.20' not found. What could be the issue ?

Is it required to export PATH ?

Kindly suggest me to solve this issue !!!

Regards,

Rajesh Kannan S

Hi Rajesh,

Can you try exporting PATH and see if it works?

Regards,
Rishabh

Hi Rishabh,

Thanks for your reply.

I have generated vsdk_linux.out from Makefile. Now I couldn't able to see GLIBC error !!!

My usecase is :-
NullSource (A15) -> Decode -> VPE -> Dup -> Merge -> Sync -> Alg_DmaSwMs -> Display.

Link Id's :-
pObj->NullSourceLinkID = A15_0_LINK (SYSTEM_LINK_ID_NULL_SRC_0);
pObj->IPCOut_A15_0_IPU1_0_0LinkID = A15_0_LINK (SYSTEM_LINK_ID_IPC_OUT_0);
pObj->IPCIn_IPU1_0_A15_0_0LinkID = IPU1_0_LINK (SYSTEM_LINK_ID_IPC_IN_0);
pObj->DecodeLinkID = SYSTEM_LINK_ID_VDEC_0;
pObj->VPELinkID = SYSTEM_LINK_ID_VPE_0;
pObj->DupLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_DUP_0);
pObj->MergeLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_MERGE_0);
pObj->SyncLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_SYNC_0);
pObj->Alg_DmaSwMsLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_ALG_0);
pObj->DisplayLinkID = SYSTEM_LINK_ID_DISPLAY_0;


While creating SwMS algId I got assertion Error !!!

Hi Rajesh,

The error message says that you are allocating size 0. Can you check the same.

Rishabh

Hi Rishabh,

I checked the source code, while creating AlgPlugin_create is getting Failed !!!
status = (*(gAlgorithmLinkFuncTable[algId].AlgorithmLink_AlgPluginCreate))
(pObj, pCreateParams);
In Usecase it's created for Mosaic Link Id :-
pObj->Alg_DmaSwMsLinkID = IPU1_0_LINK (SYSTEM_LINK_ID_ALG_0);

In which scenario is getting FAILED !!!

Kindly suggest me to solve this issue !!

Regards,

Rajesh Kannan S

Hi,

can you please step in inside the below function and check where line is exactly causing the issue.
There are few function which will be called from create function , please check inside those also.

AlgorithmLink_dmaSwMsCreate()

Anuj

Hi Rajesh,

You should use CCS, single step the code and see where exactly issue is occurring.
Maybe there is some NULL pointer that you are trying to access.

Regards,
Rishabh

Hi Rishabh,

Thanks for your reply.

Could you guide me how to use CCS ?

While creating Mosaic link what should be the width & height ? From NullSrc (1920*1080) it's configured.
4 * 4 output I supposed to see in Display (HDMI).

Usecase :-
NullSource (A15) -> Decode -> VPE -> Dup -> Merge -> Sync -> Alg_DmaSwMs -> Display

Kindly suggest !!!
