RTSP stream frequently interrupted causing recording gaps (AVERROR_EXIT)

[rivandraa]

Description :

I’m experiencing frequent RTSP interruptions when recording a stream via go2rtc. This causes the MP4 recorder to stop and restart repeatedly, resulting in recording gaps.

can you check the quality of your network connection. network problems: WLAN camera?, could be switch-drops or paket loss. This is the key indicator. AVERROR_EXIT in FFmpeg/libavformat does not mean a network timeout in the classical sense, but rather that the RTSP read operation was interrupted from the outside.

My setup uses a Wi-Fi connection, so RTSP stability shouldn't be an issue. I'm running this on an HG680P. Does LightNVR require higher specs or specific tuning compared to motionEye? I had no issues with packet loss or drops when using motionEye on this exact same hardware.

I've already tested a direct LAN cable connection to the LightNVR server, but the result is the same.

@rivandraa one thought is to try disabling audio on that problematic stream and see if it improves.

I've already tried all the configurations—disabling the audio, lowering the resolution, and reducing the FPS on the CCTV—but the result is still the same.

Do you by any chance use Dahua camera's?
I had the same experience using this brand. Did not find the time to do further investigation.
