Other Parts Discussed in Thread: TVP7002

My software version is ：ipnc 3.8

My demo is ：multich_capturedisplay.c

In the process of data collection and processing can call a function VpsUtils_queGet () to collect data,

Below is the function body：

do{

if（handle->count>=minCount）

{

..........

}

I want to know where the count value is assigned，not found in the code.

Hi，Gajanan：
Thank you for your reply!
I know that count is Incremented in VpsUtils_quePut,But I don't understand what conditions make VpsUtils_queGet able to get a frame data.
I use the capturelink , I think External input a frame data, the program will generate an interrupt, but I didn't find the interrupt the callback function.

Hi,

Below is the flow for putting data to FullQue.

File: vpsdrv_captureList.c

Vps_captTskListUpdate -> Vps_captTskUpdateList -> Vps_CaptTskPutCaptFrm/ Vps_CaptTskPutCaptField -> VpsUtils_quePut(fullQue)

Hi，Darshan ：
My software version is ：ipnc 3.8
My demo is ：tvp7002 input data-->capturelink--->displaylink--->hdmi out data
The phenomenon is can display static image only.
Print out debug message, indicating "pFrame->channelNum==VPS_CAPT_DROP_FRAME_CH_ID" ,so the function " VpsUtils_quePut(fullQue)" is never called.
I don't why?

It means you are enqueueing any frames to the capture driver, so it is dropping all the frames..
You need to enqueue few frames to get captured frame back in the application.

Can you give me some advice to debug?

Hi,

By default IPNC RDK is supposed to capture from Camera Sensor. Did you modify multich_capturedisplay.c File to capture from TVP7002 ?

Thanks,

Darshan
