🌐 Network testing tool for SRT protocol

SRT Probe is a network testing and performance measurement tool for connections using the SRT (Secure Reliable Transport) protocol.

It visualizes real-time statistics such as RTT, throughput, and packet loss, supporting network quality evaluation.

Designed for connection testing only, it does not handle video/audio input/output.

✨ Key Features

📊 Real-time Statistics: Instantly displays RTT, throughput, and packet loss
📈 Performance Charts: Dynamic graph visualization
🔄 6 Sender/Receiver Modes: Caller, Listener, and Rendezvous combinations for both sender and receiver workflows
🔐 SRT Encryption Settings: Configure a passphrase and AES key length for encrypted SRT tests
🎯 Target Throughput Control: Set the target throughput from 1 to 100 Mbps and adjust it while a test is running
🧪 Connection Diagnostics: Check settings, local encryption settings, local network information, executable status, routing hints, Windows Firewall state, and recent logs
📋 Copyable Diagnostic Reports: Copy diagnostic results as text for issue reports and support requests, or hide them when you do not need the panel
🧭 Connection Mode Guide Logs: Show the next peer-side startup action when you select a test mode
🧾 Test Summary Logs: Output start time, stop time, duration, mode, throughput, RTT, packet loss, and result when stopping a test
🧾 Automatic Log Saving: Save statistics logs and regular logs automatically as per-instance local files
📂 Log Folder Buttons: Open the shared log save folder directly from Statistics Log and Log Output
📐 Resizable Log Areas: Adjust the statistics log and regular log display heights and keep the layout for the next launch
