Python deepstream-test2 substitue from file to H264 RTP source - Perofrmance low

I’m just found the demo doesn’t work. Luckly, I have got it working.

But I don’t have time to find the rootcause, and it needs to test those combinations and more expertise is needed here.

As you said, I think dig deep might be know what’ going on with the demo code. Hope to know more.

Right now, I have to be focused on How to configure RTP source in deepstream-app 7.1?.
