OBS 30.1.1 not showing frames missed or skipped due to rendering or encoding lag in Stats.

[Worsel]

I have noticed since I have upgraded to OBS 30.1.1 that the Stats are not showing when there are any frames missed or skipped due to rendering or encoding lag. My stream will suddenly turn into a slideshow for a brief moment but the Stats continue to show zero out of however many frames have been pumped out to that point in my stream.

I have checked the log file for my last stream I just wrapped up with the Analyzer, and it says that I had a 1.4% CPU Encoder Overload (I use x264). I rely upon being able to see when this happens so I can work on tweaking my stream setup to ensure it stays smooth the entire time, so this makes it a little tricky to see what I should adjust. I am sure this is also not the place to make this suggestion, and maybe something like this already exists and I just don't know about it, but having an alert or pop-up saying frames are being skipped or missed would be useful too since I currently have to have my phone open to my Twitch account so I can try to spot when the unreported drops happen.

This is my first time posting to this forum for assistance so please let me know if I have forgotten to include any required information that is needed, and I thank everyone for what they do.

Have a look at t he output from the OBS Log Analyzer..

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

See if you can address the issues raised and try again.

Not to be rude, but I most likely am going to be anyway, but how am I to "See if you can address the issues raised and try again" when the issue is that OBS itself is not showing any missed or skipped frames in the Stats section when I am streaming? Did you read what my issue was at all, because I seriously doubt you did.

Unless you can tell me why OBS is refusing to tell me there is a problem in Stats when I am live or point me to where there is an official bug reporting location as I suspect that this issue is, then I don't see how your comment would be of use.

Is there a problem with the stream if it will occasionally miss or skip frames? Sure, I know that, I saw it happen. Tell me why OBS is not reporting it in Stats and then I will listen to you.

Please, add info from what version you have upgraded. And what status window you are using: standalone (has minimize, maximize, close buttons) or dock-pane(only close button).

According to the profiler info at the end of your log, the encoder is running well below the maximum allowed time (usually up to 5 ms, allowed is up to 16.6 ms per frame), but it also spikes up to 576 ms, which is probably the reason for your 1.4% dropped frames. Since you're using x264, it's the CPU that is not able to encode a few times. Such spikes may be caused by overheating and the CPU is throttling. Or you have something on your laptop running that uses up all CPU resources for a very short time.

My Windows 11 has been de-bloated and anything that was not necessary for WIndows to run has been disabled or uninstalled. I pause my Windows Updates before I start streaming, as I did find that it would check every 20 minutes in the background and it would sap CPU power; once I am done streaming I make sure to unpause it so critical updates can be patched in. Any time an update is done I also make sure to check again that no extra programs are creeping in or running in the background that will cause any spikes.

For everyone who can't seem to understand the issue let me try this again: OBS 30.1.1 not showing frames missed or skipped due to rendering or encoding lag in Stats.

I don't care if I dropped frames or had an overload, I know I did and I saw it happen. I am also testing out different settings to try and refine quality settings more to my liking. The issue is that OBS IS NOT TELLING ME that frames were missed or skipped, it just shows zero frames missed the entire time.

Please, add info from what version you have upgraded. And what status window you are using: standalone (has minimize, maximize, close buttons) or dock-pane(only close button).

I had gone from the 30.1 Beta 3 build to the current 30.1.1. The Stats window is docked into my OBS along with my Twitch Stats and Twitch Activity Feed.

@Worsel Hi, i just created an account after using OBS for so many years. I had the same issue as you just after updating my OBS yesterday. Now i have found that i can turn this issue on and off by simply enabling/disabling any up or down scale filter. For me it was under Streaming Encoder settings the rescale output setting, if i turn it on to ANY value it will stop showing the frame numbers as described in your issue, turning that setting to off will show them again, no restart needed.

I checked your log and saw that you have rescales enabled in multiple places, could you test if that fixes your issue (even if it overloads your CPU with rendering in 4K XD)

Edit: Retested the Settings->Video->Rescale setting and that works while still showing the frame numbers

Edit 2: https://obsproject.com/logs/nRRRBOYYN0byXOkf Ignore the warning, i just added stuff for testing
This log contains multiple runs, the ones without rescale at the encoder setting all worked fine, the ones where a rescale was set at the encoder had the described issue

Looking through the logs i also notice that the logs DO NOT show when someoneset the downscale filter in the encoder setting only the one that is set under Settings->Video. You see that i changed the output resolution multiple times through out my testing, but you dont see which filter i used, only the resolution

Logging back into this site after figuring out the same thing you discovered as well. I have since had some major "breakthroughs" on x264 encoding and getting the best picture for my Twitch stream, and that pretty much involves turning off all rescalers. It's SUPER easy to accidentally turn on more than one if you're not careful and OBS does not warn you about it at all.

Now I am off to figure out if anyone knows how to get OBS to play nice with Elgato 4K X capture cards because Corsair is pretty much forcing the audio to 44khz and OBS HATES it so you get a LOT of pops and clicks from the mismatch. Setting OBS to 44khz and every single audio source you can think of in Windows 10/11 to the same and it STILL pops and clicks. Gotta love it.
