New To OBS Getting Error

[RevDia]

I am getting a "Starting the output failed. Please check the log for details."

I have updated my NVIDIA GeForce driver. I am attaching the log.

I am worried that the machine is missing something that would allow it to run properly but I don't know what that is.

According to this, looks like trying to use Intel QSV encoding
14:10:03.404: [qsv encoder: 'simple_video_recording'] debug info:
14:10:03.419: [qsv encoder: 'msdk_impl'] Specified object/item/sync point not found. (MFX_ERR_NOT_FOUND)
14:10:03.419: [qsv encoder: 'simple_video_recording'] qsv failed to load

The listed Available Video Encoders don't show NVENC... have you checked to see if the NVIDIA GeForce 940MX supports NVENC ?

I'd recommend submitting your log to the auto analyzer (see my .sig) for anything else... but the above is where you need to start
*IF* your 940MX does NOT support NVENC, then you need to make sure you have right drivers {and OBS Studio config} for Intel QSV encoding

GeForce 940MX supports NVENC

Googling that exact phrase (select and right-click for me) has this as the first hit:

NVENC encoding on 940MX

Hi guys, I have succesful experience with using NVENC h.264 video encoding on 760 and 960M GPU. But whan I try to use NVENC h.264 video encoding on 940MX Premiere Pro CS6 writes me that “selected GPU does not have NVENC H264 hardware-capability”. I can not believe that NVIDIA puts away NVENC...

Looks like there are two versions of that card with the same name. The only difference to a customer is the fine print. One version does, the other does not. Grrr.

I was taking the teach to fish vs handing over a fish approach ... I figured it was easy to find out... but in a rush for time, simply pointed OP in the right direction.. and the MX was a laptop model, so really an OEM selection/choice... back when NVENC support/usage (streaming in general) was much less than today... so save a few pennies, lower W usage of GPU to extend battery life by excluding that chip/support?

for those that came across this later, from the above nVidia community post
Nov 01 '20 940MX uses GM107 (nvenc supported) or GM108 (nvenc unsupported). Please check your card PCIID and search PCIID repository.
