CCS/AM5728: Dual camera encode

Tool/software: Code Composer Studio

Hello,

I want to use two camera to encode the source which  the dual camera capture on my own AM5728.

However, in the gstreamer tutorials there is no example of running multiple pipelines in an application.

And I have tested the camera whether it have a problem or not. The camera worked well.

And I checked the website: 

https://e2e.ti.com/support/arm/sitara_arm/f/791/t/587937?tisearch=e2e-sitesearch&keymatch=dual%20camera%20encode

but I didn't find anything useful to help to solve my problem.

So could help me and give me some advice to help me.

Thanks&regards!
