Thanks to this feature, it offloads the resource-eating task from the CPU to a specific part of the GPU.  Also, it is good to know that many live streaming and recording programs, for instance, vMix, Wirecast, Open Broadcaster, and Bandicam support the encoder. Moreover, the NVIDIA Encoder enables you to capture your games and share them. This is included in NVIDIA’s GeForce Experience software. In this article, we explain how you can solve all the OBS Studio NVENC errors you might run into when you are using OBS.

How do I enable hardware encoding (NVENC) in OBS?

If you’re asking what is NVENC codec, it is a tool for hardware encoding available in both Mac and Windows versions of OBS. But for the best result, it is recommended by the developers to use encoding on computers running Windows. Also, it is best used with NVIDIA GPUs. Hardware encoding has been available on NVIDIA cards since early 2012.

How can I fix OBS NVENC errors?

1. Fix the OBS Studio NVENC error unsupported device

2. Fix the OBS NVENC error: Too many concurrent sessions

OBS NVENC error that says you have too many concurrent sessions means that you have more concurrent encoding sessions than your GPU supports. Up-to-date GPU drivers can support up to three sessions, while the older drivers cap at two sessions. If you think you do not have this many concurrent sessions, reboot your computer.

3. Fix the OBS NVENC error failed: 8

The complete error message for this issue is accompanied by the NV_ENC_ERR_INVALID_PARAM specification. The reason for this error is that NVENC does not support resolutions that are higher than 4096 on their largest side and it fails to capture or show anything. You should set your output resolution to be lower than 4096 on its largest side. Base (canvas) resolution can be the larger one rather than the output (scaled) one if you need it to.

4. Fix the OBS NVENC error init encoder

To fix the Init encoder error, you need to update your NVIDIA driver to its latest version. SPONSORED If the solution above wasn’t enough, visit the NVIDIA driver download section and get the latest driver from their website. Make sure to get the corresponding version for your hardware. Otherwise, you risk getting other graphical errors and system problems like BSoDs. To avoid that, use a tool like DriverFix that detects the hardware you run and automatically downloads corresponding drivers. Also, replacing the nvEncodeAPI.dll located in the following directory with previous versions of this DLL file can help fix OBS Studio NVENC errors: C:\Windows\SysWow64 You need to boot into Safe Mode to be able to do this. Previous versions of nvEncodeAPI.dll can be found in the following location: C:\Windows\System32\DriverStore\FileRepository\nv_disp.inf_amd64_neutral_

5. Fix the OBS NVENC error invalid param

The maximum resolution you can aim for in an NVENC h.264 is 4096×4096. However, NVENC h.265 supports resolutions of up to 8192×8192 pixels. The point is that h.265 is not supported by streaming services. You can only use it with the FFmpeg output of the OBS. So, you are going to go for the 4096 one mostly.

6. Fix the OBS NVENC codec: Function not implemented

How can I fix the OBS NVENC Encoding Overload?

One solution that can fix this OBS NVENC error is to reduce the frame rate. If you’re capturing at a high frame rate (48 to 60), you may experience lags. This can happen for a number of reasons. However, the main reason is that your GPU cannot render the game itself as well as the video you’re streaming. If you haven’t updated your drivers on OBS NVENC after you open NVIDIA GEFORCE EXPERIENCE, click on the drivers and update them. Make sure to reboot your computer afterward. You can also use ICQ as the rate control and set the ICQ quality value between 20 (better quality, larger files) and 23 (diminished quality, smaller files). Remember that OBS uses a fabulous open-source video encoding library – x264. You can set your x264 encoder preset to ultrafast to reduce CPU usage.
