TDA4VM: TDA4 create 8 capture node

Part Number: TDA4VM

We use TDA4 EVM.

We want to create 8 capture node for 8 different camera.

When we create 2 capture node , capture node can dequeue successfully and receive data from sensor.

But when we create 3 capture node, capture node can not dequeue successfully.

How can we create 8 capture node for 8 different camera?

Hi,

1. May I know which SDK version are you working on?

2. Could you share the details on how you are configuring 8 capture nodes?

Regards,
Nikhil

1. We use SDK7.3

Hi,

Are you using difference camera for all 8 input cameras? If not, you could just use single capture node instance and capture from all 8 cameras using single instance.. Any specific reason for creating multiple capture node instances?

Regards,

Brijesh

Hi Brijesh,

In our project, we may combine defferent camera types. Please help to let us know how to setup more capture node to meet this request. Thanks!

Hi Mike,

On which target are you running all of these nodes? If not tried already, can you run them on separate targets? Capture node supports some 8 targets..

Hi Brijesh:

TDA4 connect 8 sensor with YUV422 output format

These 8 sensor resolution is all different.

How can I set these 8 capture node?

Hi,

You would be calling tivxCaptureNode() 8 times I believe.
Please do the below to set node on the target.

status = vxSetNodeTarget(capture_node1, VX_TARGET_STRING, TIVX_TARGET_CAPTURE1); // for the first node
status = vxSetNodeTarget(capture_node2, VX_TARGET_STRING, TIVX_TARGET_CAPTURE2); // for the second node
.
.
status = vxSetNodeTarget(capture_node8, VX_TARGET_STRING, TIVX_TARGET_CAPTURE8); // for the eighth node

This way you could run 8 capture nodes on 8 different targets TIVX_TARGET_CAPTURE1..8.

Regards,
Nikhil
