Live image isn't live

When I launch OBS it displays the 'live' video from my camera, but then when I stream it the audio immediately begins to drift out of sync with the video. I have discovered that what seems to be happening is that the live image isn't live at all. Its being buffered somewhere and is then being played back to me at a slower speed. The audio, however, remains live and so this is why it goes out of sync.

If you look at this picture here you can see my system time vs the time of the video. I started OBS last night before I went to bed and both the times were in sync. I left it overnight and now its about 13 hours later and the 'live' video is now 33 minutes behind!

How can I stop it from doing this? I want to have a 24/7 steam but it makes it impossible because after a few days its out by hours. I want it to be showing literally the live image.

Here is my log:

Possible issues

That is an older CPU for the computationally demanding task of real-time video encoding. Optimizing both Operating System and OBS for an under-powered system may be needed. I can't say for sure without OS performance metrics, and this OBS log does not show a completed recording/streaming session, so important info not present (which may or may not assist in troubleshooting)

Then, is that a low-end security camera you are connecting to? if yes, it may not have consistent video processing latency (as not really required of a security camera). Is the audio coming from that same camera? I don't see another audio source configured in the log

Realize that OBS is working hard once you have a video source enabled in a Scene (Recording/Streaming will impact Encoding workload, but the Rendering workload starts with simply running OBS). Audio takes a lot less CPU to process

In general, I recommend monitoring hardware resource (CPU, GPU, RAM, Disk I/O, etc) utilization [for ex. using Task manager’s Performance tab and/or Resource Monitor] to see if your system is being maxed out with your settings https://obsproject.com/wiki/General-Performance-and-Encoding-Issues and https://obsproject.com/wiki/GPU-overload-issues
