How to reduce the latency of video streams when the internet speed is slow?

Hello everyone, I am using ambmini and custom AI tracking models for specific object recognition and position tracking. I have found that when I use VLC media player to view video streams, there is a delay of nearly 5S or more. Can I configure some items to achieve higher real-time performance? Although my wireless network speed is relatively poor, I hope to ensure real-time tracking as much as possible, even if there is local cache or TF card before slowly uploading to devices such as computers. I wonder if there is a way to optimize the delay during live streaming

You can update the VLC “Caching time” to be “1000ms” to reduce some delay. Other than that, improve the internet is the best way. I suggest using your cellphone as hotspot.

I have set VLC to 1000ms by default. I will try using my phone’s hotspot as a network connection. Thank you for your reply

I have the same setting as you, 1000ms and phone hotspot. the latency is very small.
So, I don’t think it is an internet issue.
Could you try a default AI example to compare?
