Bug Report OBS Crashes - libx264-142.dll - obs.exe - obsapi.dll

[Makkusu]

I have been trying to stream and/or record using for the past couple of months and sometimes when I am trying to do this I get crashes. Weird thing is that sometimes my game crash and sometimes OBS crashes. I've tried to TS my machine and check my raid and sdds and my ram but all tests came out with no erros, ended up running memtest for about 12hrs.

my specs are 8gb 2133mhz cas 9, 240 neutron gtx ssds in raid 0 and an external 1TB seagate USB external (this is where my files are saved) STBX1000201, 3770K @ 4.5 (OC tested 24hrs), GTX 780.


This was my latest error

I first thought it was my ram and I ran memtest for about 12hrs with no error. I have not tried to uninstall since I read a couple of bug reports and answers that libx264-142.dll be buggy, i made sure that CFR was checked like it was advised. Most of the errors I have are from libx264-142.dll. As soon as OBS crashes or my game crashes I stop using OBS or I just simply close it because I want to game lol.

I had the error today and I decided to restart OBS and try to record anyways. I recorded for 28 mins without issues. I have also recorded for hours without issues. But I get discouraged and most of the time when I get a crash whether it is OBS or my game while ruining OBS I simply stop streaming and/or recording.

What I find curios is that sometimes my game crashes too. But I have game for hours without streaming or recording and I never have my games crash. The only link for my crashes is when OBS is running. I am not a software guy, I don't know if there is a correlation between the crashes.

I will upload a file with the dumps and with the log of my successful recording without any crashes on a zip file. I will take any advice and I will answer any question you might have.

These are definitely stability related crashes. You likely have bad RAM or an overheating / overclocked CPU or weak power supply. It may only exhibit problems under heavy load. Try with this program to verify your system is stable:

Those were my thoughts exactly. I don't know if you read my post completely, I did mention I ran memtest recently for 12hrs or close to that, do not remember correctly. My cpu is overclocked also, also mentioned in the post BUT I only testes stability when I overclocked, that was close to a year ago. I will use prime95 for 24hrs. I monitor my temps closely and they don't go above 65ishC (stress testing around 80/85 that i remember), my cooler is an aio h2o unit from corsair, h100i with a pair of nf-f12s. I will use linX and follow the rest of the guide. Any instability for minimal it might be I want it gone.
I forgot to mention I did use OBS previously without incidents. They started recently after and update. That is why my first thought was to test my ram. I will find sometime to run it for at least 24hrs.
I didn't mention my PSU since I can also monitor it because it digital and I am really positive it is good. It is a corsair ax860i. I have an outlet meter and also software to check the readings since the psu allows it.
Thanks for the advice. I will post the results.

 

[Makkusu]

I ran one test without errors following the guide for my CPU type. All 8 cores, all ram, 10 minutes. I also monitored my temps, my hottest core got to 87c.

And I have to apologize for the wrong into. I ran memtest for 9hrs43mins for 8 passes / 0 errors. This was about 3 weeks ago.

Where do we go from here ?

 

[Makkusu]

I ran a second test with a couple more monitoring software available. I tried to find the peak temp of 87 and snap a screenshot. Happened about the 5 minute mark as you can see and also a screen shot with the test results, no errors again. When my 780 is working it draws about 240-250w, that will put my power consumption around the 500w range give or take, this is the only thing not visible since the gpu is not being tested in any way.

 

[R1CH]

Does the 32 bit OBS also exhibit the same problems?

 

[Makkusu]

Does the 32 bit OBS also exhibit the same problems?

Tbh I have not tried obs 32bit at all. I can if you need me to. Any specific settings you want me to try? Also I forgot to mention (but is in the OS version section in the log) I am running Win8.1 Pro 64bit. Other than that my 'specs' are the same from the first post.

 

[R1CH]

Just try the same thing in the 32 but OBS. The 64 bit version gives no real benefits.

 

[Makkusu]

I crashed both times I tried to run, crashes happened really quickly. But there was no window telling me OBS crashed and there was no crash report. This is for the 32bit client. Game was fine tho, no low fps or anything that would indicate that I was having an issue in game and temps were under 75c. Both times OBS crashed and my game was good before and after.
The 32bit OBS seemed to crash faster than the 64bit. I did notice something in the regular logs of the 32bit version. At the end I had this lines

2 of the logs had that stalled line. I was trying to stream and record at the time. I checked both the file in my hard drive and the file saved in my computer and also what was the last thing I saw in OBS. The moment OBS crashed was after the file and the stream file ended. They both ended at around 1minute 6 seconds but the last thing I saw in OBS was after that. I did not see any dropped frames in the OBS screen. Like the log says, there were around 26 seconds that were not 'written'.

 

[Makkusu]

let me know if there is anything u want me to try

 

[Makkusu]

I decided to make sure I uninstalled and re installed OBS and check windows for error. Uninstalled OBS, removed the folders from program files (both 32bit and 64bit folders) and my appdata/roaming/obs folders completely, used ccleaner to remove and clear my registry from anything (just in case). I also did a system file check, i found errors that were not fixed by it, checked the logs and found the a couple of lines with the error pointing to the file prncacla.inf and had to use dism to fix the issue, also uninstalled my asus xonar drivers for the latest uni xonar driver since their new release supports win 8.1. I also checked the rest of my drivers to make sure they were up to date but I had to make no more changes.

Then I decided to give it another try. It seems to be working, I streamed and recorded today for a couple of hours without crashes from OBS or LoL (the game I was streaming) and with my settings (all of them mostly default) my CPU was around 65% load, it never reached 100%, closest was around 85%. Temps were really good, around the 60c.

I don't know what fixed the issue (or at least it seems to be fixed) for me since I took so many steps at the same time. Here is my latest log. I streamed and recorded for over 1hr. I did notice some problems with the client for lol but I already posted my experience in another post.

Thanks for your time, if there is more data I can give you let me know. Great piece of software you guys have.

 

[Makkusu]

Nvm... I got crashes today. both 32bit and 64 bit. The 32bit client just crashed with no prompt. I was able to get a screen shot a few secs after it happened with my task manager up on the performance tab, you can see my cpu utilization is around 50%ish. I really want to stream and record and I like OBS, it didn't used to give me this issues until recently.

 

[R1CH]

Try running LinX for several hours, I still think this is some kind of system stability problem.

 

[Makkusu]

I set LinX to run for 500 minutes with all ram. Ran for the full amount of time with no errors. I have tested my OC with prime95 for 24hrs prior to this with no crashes but it was a long time ago.

​

This test had my cpu usage at 100% I am pretty sure 100% of the time it was running. I checked every 2hrs opening the task manager and also to check my temps. OBS + what ever I am capturing never goes above 65%ish. I don't see how a stress test can't manage to destabilize my pc in 8+ hours bout OBS can in 20 minutes. When I first started to get this crashes I also tested my ram for 9hrs and 43 mins, so I know my ram is good too.

I know most software people are bent around blaming hardware but I think at this point there must be something else that OBS doesn't like and it must be software. That being said I don't want you to think I am insulting you in any way, I am not a software expert (not much education on it, just a few college courses) and I will run any tests you want/need me to run. Are there any incompatibilities with other programs that you might now? I can give you a list of everything I have installed. I want to help in any way I can.

I could send you my specs and more info since I can make a text file with speccy but I wont post it or uploead it here since it has some delicate info, I can erase the most obvious ones but you never know, I will feel safer if I can email you that file directly.

Overclocks are easy enough to restore. Just copy down the settings from the BIOS, and restore the proper CPU ratio and clock speed. Then see, if at stock, OBS still crashes. Also, I once had that same crashing error. It was my RAM. And I had to use RAMTest for 24 hours to find the issue, as the Ram glitched at roughly 20 hours in. So, If you've got the time, Run it again, or do as I suggested. Might work out for you.

About a month ago I think it was, once I first experience the problems, I restored my bios to its default settings and OBS still crashed. Since it is the only program that seems to crash I restored my OC profile and been using my pc without issues.

I've run memtest for 24hrs, same as prime95 for 24hrs when I was setting my OC on this machine about a year or so ago. I understand from them to now hardware can break. I'll start running memtest86+ now. Ill snap a pic of my monitor in 24hrs.

After your test. Just for fun, Try removing one RAM stick from OBS, and see if it crashes. If it does, swap it out, and have the other one in by itself to see if it does the same thing.

I am sure you meant remove one stick of Ram from my mobo, not from obs, that is only... logical.

Ill do that for both even if with one obs manages not to crash for the sake of TSing.

 

[Makkusu]

Pass 18, errors 0, 24hrs.

Ill do the individual ram stick test on my 'mobo' later on during the day and I will post my results.

I noticed it was almost done with the last pass so I let it finish, pass 19, errors 0, 24 hrs. And below is so you guys can see that all my info matches.
