[TDA4x] How to compose tiovx graph for using 2 cameras

Hi,

Not readily available in the SDK, but you could construct two graphs, each for different sensor input and different nodes.

This is possible. Please make sure to run two graphs in different two tasks on Linux.

Hi, Brijesh,

I would like to know how to configure different capture nodes. Specifically, the setting value for the capture parameter.

For example, if one capture node uses channel 0 and the other capture node uses channel 1, how do I set the capture parameters?

Which part of the code block below should be modified for parameter setting of each capture node?

Hi Hyun,

It really depends on how your input cameras are connected. So could you help us understand the input connection? 

Are both the camera connected to same CSI port? or different CSI port?

If they are on different port, then change port id changes. You could create two capture nodes, each with the different port id and channel id could be same for both the camera.

Hi, Brijesh,

We'd like to connect the two camera to same CSI port.

Is it possible to use different types of cameras in the same CSI port? If yes, which part of the code above should be modified?

Thanks & BR,

Hi Hyun,

It should be possible from CSIRX point of view, but let me double confirm the same. 

Any specific reason for not using separate CSI instance? If you are planning to use only two camera, better to use separate ports.

Hi, Brijesh,

Thanks for reply.

For now, it doesn't matter to use the different CSI port.
We need to check possibility of usecase using different cameras and to confirm whether the performance requirement is satisfied in advance.

Thanks & BR,

Hi Byungjo Hyun,

Any further question on this thread?
