The method or source code for the support multichannel RTSP in the DeepStream2.0

1、I must support multichannel RTSP in the field of security monitoring
2、My model is tensorflow model.
3、The GPU is Tesla P4
So I want to support support multichannel RTSP source.
The deepstream-test1 in the DeepStream_Release/sources/apps only support single RTSP source.
Can you tell me the method or source code for the support multichannel RTSP source interface。

Please not make multi threads for same issue.

deepstream_app, only work with files, can’t work with multi rtsp…
