Tool/software:

Hello I am using tda4vh sdk 9.2 version.

I want to apply two different ldc to the same camera in multicam codec

I'm just saving it after encoding without decoding.

so I want to make one more viss, aewb, and ldc node by referring to the example in multicam app

I have a question about it.

1. Is there a related patch file

2. Is it right to add viss, aewb, and ldc to the init, create graph like multicam

3. In the original code, the output of ldc is put into the corresponding array obj->enc_pool.arr[0], but can I put the output of the newly created ldc1 into obj->enc_pool.arr[1] ?

Thank you

Hi,

In order to use two LDC nodes with different parameters, you would need to add second LDC node, and then connect the output of this second LDC node to encoder node.

There is no example of this application, but you can easily add it by referring to existing example.

I'm trying to create two nodes and put each result in en_pool.arr[0],

is there a way to access a specific index of en_pool.arr to put output_arr as a result of ldc2?

Also, In multicam codecI registered ldcobj.node as a graph parameter by referring to en_pool.arr[0] with the current function 'add_graph_parameter_by_node_index', do I need to add the same if I make ldcobj2?

Hi Kim,

Well, yes, you can get the parent object array in the LDC node and then from the object array, you could get the specific instance..
