Hi ,

There are some modules disabled in kernel and built for certain usecases .
AVB is one of them

3.1 The usecase chain will have capture / null src as input source for the stream .
Hence the steps to be followed to build application for all capture usecase ,

3,2 The usecase uses AVB (network) as capture source, Here Networking is disabled from kernel and handled at ipu .
Hence changes to be done to disable ethernet from kernel.

Yes you need to use null src as input ,
3.1 is the build you need to use.
