Hi,

My requirement is 1920*1080P、30fps、3ch(VIP2 S2 A、VIP3 S1 A、VIP3 S2 A)

SDK : PROCESSOR_SDK_VISION_03_05_00_00

usecase : Chains_lvdsVipMultiCam_Display

decoder : techpoint TP2824 * 2

Q1:

How to set in the orange box in the second picture below
For example, if I use 25fps, do I need to modify the fps parameter?

Q2:

I have seen channel 2(vout 6) but other channels only have black screens

First, I modified the PINMUX and Capture parameters as shown below:

C:\PROCESSOR_SDK_VISION_03_05_00_00\ti_components\drivers\pdk_01_10_01_06\packages\ti\drv\vps\src\boards\src\bsp_boardTda2xx.c

And then i modify the VidSensor_CreateParams below:

C:\PROCESSOR_SDK_VISION_03_05_00_00\vision_sdk\apps\src\rtos\video_sensor\src\vid_sensor.c

vcaptureSrc = CHAINS_CAPTURE_SRC_OV10635

vChainsCommon_MultiCam_StartCaptureDevice

v=>

vChainsCommon_SetVidSensorPrms

v=>

vChainsCommon_SetVidSensorMultiOV10635Prms

C:\PROCESSOR_SDK_VISION_03_05_00_00\vision_sdk\apps\src\rtos\usecases\common\chains_common_vision.c

8 bits changed to 16 bits have an impact

Result

Capture link can capture 30 frame

Hi YiTing,

From the capture links stats, three channels are already being captured at 30fps rate. Which means, capture is working fine. You need to check your rest of the data flow and see where other 2 channels are dropped.

Hi Brijesh,

Thanks for your reply.

To ensure the chain simple that I only use capture link to display link.

I use funtion"chains_lvdsVipMultiCam_Display_SwitchDisplayChannel" to check that the rest of the data flow is all black screens.

In multi-channel capture, if I can capture one channel, other channels are also set correctly?

I just want to confirm whether bt1120 is set correctly.

YiTing

Hi YiTing,

Atleast from the stats, it looks like all channels are getting captured at 30fps. Can you try saving a frame from each channel and analyze it offline?

Also Can you please check VIP size register to see if VIP detects correct size for each channel?

Hi Brijesh,

I don’t understand what the analysis frame means
Do you need me to analyze the pixels in the display link frame?

I will check VIP size register within two days

Hi YiTing,

I wanted you to save a captured frame and view it offline to see if the captured frame is correct and is not black..

Hi Brijesh,

How to save frame in the CAPTURELINK, do I need to add Link like null link ?

Hi YiTing,

One way is,

you could put break-point on CaptureLink_drvProcessData API and then run the code upto line 758. Once you get pFrame (Fvid2_Frame), you could get the buffer address from pFrame->addr[0][0] and from that address, you could dump the memory from CCS memory window.
