Question

Hi, I'm testing MediaMTX, and I came across this error.
Has anyone else experienced this?

What are you streaming protocol are you using? Also are you using TCP or UDP?

[steinhorstbr]

rtsp, tcp.

this is impossible to replicate if you do not provide MediaMTX version, configuration, logs and a file that allows to replicate the issue. Open a bug report and provide such data.
