Question / Help File Recording with stream suddenly halt randomly

Hi,

In the past week, my live streams has been interrupted several times with this issue, what happens is that I would notice my stream was interrupted and offline while OBS did not sense that nor did it crash. However, when I click on stop stream (which is already stopped anyway) and file recording just gets stuck at "Stopping Recording..." and never finishes. Recorded file is locked still by the obs64 process, exiting OBS does not terminate the process and file would remain locked and unwatchable.

If I force terminate the obs64 process, then the file lock would be released and recorded file would be still watchable, however, often loses a good portion of recording, sometimes gameplay recordings that I do not wish to lose but lost due to the issue anyway.

I cannot say nothing has changed to my system, however the only notable change is using a new USB sound card (creative sound blaster 5.1 omni) since the sound chip on my MB (also creative) started causing issues that sometimes Windows was unable to detect it.

I am using NVENC (surprisingly only this allows me to have no frame drops with live streaming due to my internet's unstable and low throughput).

Basically the symptom seems like the local recording hangs causing the stream to stop as well

Any ideas what could be causing the problem?

Why are you streaming with nvenc at all?
Click to expand...

I have tried many times to use either QuickSync or x264, neither will give me a stable stream, both ended up with consistent dropped frames due to internet we have here in AU is notoriously poor...like worse than 3rd world, rank 60+ in the world, no sight of unlimited quota connections beyond ADSL 1mbps upload until at least 2020 provided the so called NBN doesn't delay again (not counting on it).

QuickSync somehow gives me lots of artifacts for scenes with fast changes...tried different settings and gave up. x264 dropping frames regardless encoding profiles...it's likely the internet just doesn't agree with it. So if I wanted a stream that does not split my sessions into many sub 2~3 min due to the drop outs or super stuttering...like 30~50% dropped frames when streaming, I can only see NVENC works for me now...it had worked even only with YouTube, but that's good enough, zip, zilch frame drops, and recorded video and streamed content only happen to have a difference of 5s every 30min...I was happy after trying to find the right setting between x264, QSync and NVENC and the former 2 never worked out, not even with OBClassic, same deal with artifacts, dropped frames...etc.

FYI my problem doesn't start until last weekend...so OBS had worked almost flawlessly for me...I will try to use the 32 bit version and test for the next few streams to see if that happens as well or it might fixes it.

PC setup provided below might help:
i7-4770k
GTX 760 main adapter (driving 2 monitors, used to drive all 3 monitors)
GTX 680 OBS, physics, extended desktop exclusive (driving 1 monitor, used to drive no monitor...however when driving 0 monitors I always get encoding overload message)
24GB RAM
SSD read caching via PrimoCache, no SSD for direct storage at all, drive recording to is a 2.5" 5400rpm drive WD7500BPVX to be exact

ok, I'll report back later with more tests, but update for now is that:

By letting my main card (GTX 760) driving all 3 displays again, I was able to stream for an hour without issue this time.

Is it possible that your windows updated to version 1607 this week about the same time as your obs studio issues? Just a thought. You have 10 days to roll it back from the anniversary edition. I'd give that a try. I think one of your drivers is not liking the update.

It's possible, however I've been running 1607 for more than that time now, except of course, it pushes out cumulative updates every so often and maybe one of them caused issue, as for drivers, (yes 1607 definitely stuffed up my sound blaster drivers about 2 weeks ago) I have been using driverpacks updates from SDI - Snappy Driver Installer. Not guaranteeing that it didn't cause any issues, but I did that in attempt to resolve lots of driver issues with my older devices without updated Win10 support. On one of my tablet running Insider Fast Ring, the last build 14905 almost rendered it useless, until I installed 14915 less than 24 hours ago.

I'll keep reporting on how this thing goes, had another 25min stream without issues, but that was a short session anyway.

Cheers,
