How to create bandwidth congestion during live video streaming for testing 30 January 2025, 10:57

We are conducting some tests where we need to create a real-world scenario of bandwidth congestion during live video streaming. The test setup is to stream using FFmpeg, receive on a VLC player, in a laptop itself.

May I know which product of yours supports this functionality?

If the sender (FFmpeg) and receiver (VLC) are on the same computer, you cannot simulate network congestion because no actual network traffic is used in such setup.

To create a realistic test scenario, you should use two separate computers and the SoftPerfect Connection Emulator tool for limiting the bandwidth, adding latency, and introducing packet loss.

Thanks for the information. A few more questions:
1. Can we use the tool at the sender or at the receiver? Or do we need 3 PCs?
2. Can we have it on a Virtual Machine, e.g. Virtual Box?

1. It can be either at the sender or at the receiver. Two PCs will be sufficient.
2. Yes, it can be in a VM. In this case there will be two systems running on a single PC: one on the hardware and one in the VM. The Connection Emulator can be installed in either system.
