Recordings stopping after couple of seconds.

[Pietjuhbel]

First of all, thanks for your massive afford building this fantastic application.
However, I am experiencing issues recording, the recordings stop every half a minute with the following error.
RTSP read interrupted (AVERROR_EXIT) for /var/lib/lightnvr/data/recordings/mp4//recording.mp4

Using other recording tools I can record without any halting.
Do you have any suggestions to troubleshoot this issue?

Is it a wifi cam or hardwired? Initial reaction is that the network cannot pull the stream resolution you are requesting at the rate it needs to record a valid file.

Thanks for your quick response.
The stream is FHD @ 10FPS over 2.5GBE I tried 3 different camera types however all being Dahua, they all produce the same effect.
Assuming lightNVR uses ffmpeg under the hood I tried running ffmpeg from the commandline and got this error every couple of seconds:
[null @ 0x60b7e69497c0] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 150 >= 150

This would certainly upset lightNVR, however it seems other applications appear to be less picky and just ignore the mismatched packets.
I tried the same stream in VLC and it just keeps playing without any errors at all, before I used Synology surveillance station with these same cameras and it never complained.
Do you perhaps see a way to tweak ffmpeg to ignore invalid packets in the stream?

I am doing some clang tidy code cleanup and related work right now, I will run this through my agent to see if it has any additional ideas when it frees up. Expect a 0.28.0 release later today/tonight either way.

Please recheck now 0.28.0
