Hi, everybody

I'm using RDK 4.0, LINK API, and in my usecase there are 3 Swms LINKs,

2 for HD( SYSTEM_LINK_ID_SW_MS_MULTI_INST_0, SYSTEM_LINK_ID_SW_MS_MULTI_INST_1 ),

1 for SD( SYSTEM_LINK_ID_SW_MS_MULTI_INST_2 ),

the arrangement of sc instances is shown below:

SwmsID SC Instance ID start win

===========================================================================================

SYSTEM_LINK_ID_SW_MS_MULTI_INST_0 SYSTEM_SW_MS_SC_INST_DEIHQ_SC_NO_DEI 0

SYSTEM_SW_MS_SC_INST_DEI_SC_NO_DEI 3

----------------------------------------------------------------------------------------------------------------------------------------------------------------

SYSTEM_LINK_ID_SW_MS_MULTI_INST_1 SYSTEM_SW_MS_SC_INST_DEIHQ_SC_NO_DEI 0

SYSTEM_SW_MS_SC_INST_DEI_SC_NO_DEI 3

----------------------------------------------------------------------------------------------------------------------------------------------------------------

SYSTEM_LINK_ID_SW_MS_MULTI_INST_2 SYSTEM_SW_MS_SC_INST_DEIHQ_SC_NO_DEI 0

There occured one run-time error, message is below:

[m3vpss ] 39642: Assertion @ Line: 2414 in links_m3vpss/swMs/swMsLink_drv.c: pDrvObj->fvidHandle != NULL : failed !!!

I want to know how should I arrange these sc instance?

Appreciate for any reply!

How many input channels to each SwMs are present in your usecase. Share the console logs from start of application.It looks like the maximum number of channels for a scaler is exceeded.

There are 6 input channels to Swms0 and Swms1, 1 to Swms2, and there is one Scalar LINK (SC5) in my usecase, pls ref. to http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/273589/1023204.aspx#1023204 for complete decription.

What is the maximum number of windows displayed in SwMs in your usecase. If it is not more than 6 windows pls change

/dvr_rdk/mcfw/interfaces/link_api/swMsLink.h

#define SYSTEM_SW_MS_MAX_WIN (8)

#define SYSTEM_SW_MS_MAX_WIN_PER_SC (8)

I have not modified the file "/dvr_rdk/mcfw/interface/link_api/swMsLink.h"

#define SYSTEM_SW_MS_MAX_WIN (36)

#define SYSTEM_SW_MS_MAX_WIN_PER_SC (18)

#define SYSTEM_SW_MS_MAX_WIN (36)

#define SYSTEM_SW_MS_MAX_WIN_PER_SC (18)

this is the original definition.

What else reason will probably cause this error?

I mean try changing and check if issue still exists. The issue is because the maximum number of channels for a Scaler istance is exceeded.
