Hello Sir,

How to use VIP1 PortA and PortB in the MCFW ?

SDK Version: DVRRDK 3.0.0.0

Expansion I/O : REV C

message:

[m3vpss ] 84071: Assertion @ Line: 894 in links_m3vpss/capture/captureLink_drv.c: pInst->captureVipHandle != NULL : failed !!!

I found HDVPSS source code.

in the, vps/drivers/src/fvid2_drvMgr.c

[m3vpss ] FVID2_create:FVID2_create:617: GT_0trace 1 Driver create failed!!

I don't know why not use VIP1 portA or portB.

Dose it support VIP1 portA or PortB capturing in the DVRRDK 3.0.0.0 ?

Is your requirement to have only VIP PORT A and not both VIP PORT A & VIP PORT B ?

Can you please provide the changes done to Capture Link Create Params in your usecase file.

Yes, I was trying VIP1 PortA or PortB of 8/16bits, but it wasn't okay.

pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP1_PORTA;

So, I don't know why use VIP1 with PORTA giving me some error messages, but I am use a SYSTEM_CAPTURE_INST_VIP0_PORTA of 8/16/24 bits, and it is okay.

I found some pin mux of VIP1, but it was not setting other function.

I look up a file (platforms/ti814x/src/vps_platformTI814x.c), and it is not setting DVO1 mode, so I think a support VIP1 capturing of 8/16 bits.

Please see the attached file.

Please see the attached file, it is my MCFW capture layout.

Hi Badri,

I am trying to do a 8-bit bt.656 embedded sync stream capture on VIP2 PORTB using OMX application . I am using EZSDK 5.04 .

The OMX app is not capturing frames on VIP2 PORTB ,But I can capture bt.656 stream on VIP1 PORTA using the same OMX app . Can you comment about bt.656 capture on PORTB using OMX app?

Hi Yeh and Sivaramkrishna,

Have you guys been able make the VIP1 PortB work after all?

I'm in a similar situation right now.
I have a custom DM8148 board with 4 tvp5150s, connected to VIP0-PortA, VIP0-PortB, VIP1-PortA and VIP1-PortB. I can capture video from all ports except for VIP1-PortB. I would like to know if it is possible to capture from VIP1-PortB before spending too much time on hacking the driver.

I use EZSDK 5_05_02_00, with modified capture driver. Tvp5150s are configured to output BT656 format.

Thanks,
tamo2
