Ошибки с кодеками OBS: Failed to open NVENC codec: function not implemented – решение сбоев вывода

Сегодня расскажем что предпринять если у вас появился сбой вывода в программе OBS. NVEC или AMD. Ошибка может звучать в английском варианте «Failed to open NVENC codec: Function Not Implemented» или Generic error in an external library. Симптомы у них похожи. Либо просто выскакивает окошко с уведомлением как на скриншоте ниже: «Сбой вывода. Подробности отражены в журнале. Примечание: Если вы используете кодировщики NVEC или AMD, убедитесь что у вас установлена последняя версия видеодрайвера.»

Сбой вывода. Не удалось начать запись в OBS

Причины ошибки вывода потока в OBS

Поскольку запись или трансляция стримов потребляют большие ресурсы видеопамяти все ошибки нужно начинать с проверки видеокарты и ее работы. Естественно, первым делом стоит убедиться, что вы загрузили последнюю версию драйверов на официальном сайте и обновили. Для видеокарт от NVIDIA после запуска любой игры или приложения в трее есть иконка, которая позволяет увидеть какая видеокарта задействована в данный момент. При работе с графикой и записи видео или стримов разумеется должна отображаться внешняя видеокарта.

Второе – часто программа конфликтует с продуктами от Adobe запущенными на компьютере в данный момент(Photoshop, InDesign, Premiere Pro, Illustrator или Adobe XD). Сохраните всё, что делали, выключите программу и попробуйте снова запустить запись. Эта ошибка вызвана тем, что графические редакторы задействуют ресурсы видеокарт по максимуму, а если карточка не последних поколений, выделить дополнительную память на стрим или запись она просто не сможет.

Как исправить ошибку вывода?

Если обновление драйверов не помогло, посмотрим что пишут в логах. Закройте все лишние работающие программы. Далее в запущенной программе OBS:

1. Переходим в пункт меню «Справка», «Log файлы», «Посмотреть текущий журнал».

Справка, Log файлы, посмотреть текущий журнал

Stream output type «rtmp_output» failed to start!

Файл, настройки, вывод в программе OBS

Устанавливаем значение 0 в настройках GPU

Переключаем кодек с с NVENC H.264 на любой другой

Дополнительно можно обновить саму библиотеку кодеков, если вы до сих пор сидите на Windows XP или 7. Скачать можно с любого сайта. Яндекс предлагает https://softportal.pro/codecs/. Обновляем кодеки Video Codec x264, которые как раз подходят для стрима и записи в OBS. Заодно можно установить Windows 10 Codec Pack.

Обновляем кодеки Video Codec x264 и Windows 10 Codec Pack

Выводы

Самые распространенные ошибки при работе с OBS связанные со сбоем вывода или ошибкой открытия кодеков «Failed to open NVENC codec» появляются из-за конфликтов при запущенных программах Adobe(поскольку они потребляют ресурсы видеопамяти). Либо проблемой с кодеками. Проверьте в настройках какая видеокарта выставлена. Затем обновите кодеки и если не помогло переключайте текущий кодировщик. Если что-то осталось непонятно задавайте вопросы в комментариях под этой странице и обязательно напишите какой из способов помог вам решить проблему.

NVIDIA NvEnc Guide

ABOUT THIS GUIDE
The objective of this guide is to help you understand how to use the NVIDIA encoder, NvEnc, in OBS. We have simplified some of the concepts to make this accessible to a wider audience. If you think we can improve any part of this guide or find any issues or mistakes, please post below and we will be happy to update it.

BITRATE, RESOLUTION AND FRAMERATE
Encoding is all about compressing images. The smaller the size of the image, the less we must compress it and the more quality it keeps. While the same applies for framerate, a viewer can really notice a drop in FPS but not so much in resolution, so we will always try to stream at 60 FPS.

First, run a speed test to determine your upload speed (e.g. Speed Test). We want to use around 75% of your upload speed, as the game and other programs such as Discord will also fight for bandwidth.

Then, we will determine the resolution and FPS that we can use for such bitrate. Most streaming sites have recommendations (Twitch, Mixer, Youtube) on what to use. These are ours:

* Important Note for High Motion Content. If you are going to stream high motion scenes (i.e. Racing games, some Battle Royale games, etc.) we highly recommend reducing your resolution. High motion content cannot be compressed as much, and suffers from more artifacting (encoding errors). If you reduce the resolution, you reduce the data that has to be encoded, and the resulting viewer quality is higher. For example, for Fortnite, many streamers decide to stream at 1600×900 60 FPS.

Note for New and Upcoming Streamers to Twitch. Transcoding allows a viewer to view your video on a different resolution, thus requiring a lower bandwidth. Twitch only offers guaranteed transcoding to Partners; non-partners may receive transcoding, but it is not guaranteed. This is important if your viewers are on mobile phones or their internet speed is not as fast. You may want to consider streaming at a lower bitrate and resolution to lower the bandwidth required to see your channel.

Note for Streamers to Mixer. Mixer allows you to stream through the standard protocol (RTMP) or an improved one called Faster Than Light (FTL). FTL provides very low latency. However, when you use it Mixer recommends to limit your bitrate to 7 Mbps and not use B-Frames. You select this in the OBS settings > Stream, under service.

• If you want to get the most quality, use RTMP with up to 10 Mbps and B-Frames.
• If you want the lowest possible latency, use FTL.

RECOMMENDED SETTINGS
These are our recommended settings for OBS Studio 23.0 and up. You’ll want to test and adjust these settings using a private account where you can verify you’re happy with the results.

VIDEO TAB SETTINGS

• Base (Canvas) Resolution: Set the resolution you normally play at. That is, your desktop resolution (if you play in borderless mode), or the game resolution you normally enter (if you play in full screen).
• Output (Scaled) Resolution: Enter the resolution appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.
• Downscale Filter: This allows you to select a downscale filter that will provide a small image sharpness enhancement, at the cost of some encoder workload. NvEnc is very efficient and typically runs at low utilization, so we recommend using this with the Lanczos, 32 samples option for the best quality.
• FPS: Enter the FPS appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.

OUTPUT TAB SETTINGS

And there you have it! We hope this helps you improve your stream quality and reach your goals. Leave us a comment if this worked for you or if you’d like us to update the guide with other info. Happy streaming!

ADVANCED SETTINGS
If you want to mess around with all settings, here are our in-depth recommendations.

• Output Mode: Advanced. This gives you access to all the settings. Let’s start!
• Encoder: Select NVIDIA NVENC H.264 (new).
• Enforce Streaming Service Encoder Settings: Leave this checked, this will ensure that if you enter a wrong value by mistake it gets corrected.
• Rate Control: Select CBR. This determines the rate at which frames are going to be encoded.
• Bitrate: Enter the bitrate appropriate for your Upload Speed, as we discussed in the previous section. Keep in mind that some platforms have a maximum bitrate (i.e. for Twitch it’s currently 6000 Kbps, for Mixer it’s 10,000 Kbps).
• Keyframe Interval: Set to 2. Streaming platforms may limit what you can select here, and most require a setting of 2.
• Preset: Select Max Quality. This determines how much load we put on the encoder to get more quality. NvEnc is incredibly efficient, so most users can select the maximum setting. If you get encoder overload issues, change this back to Quality. Max Quality and Quality differ in that Max Quality uses 2-pass encoding.
• Profile: Set to High. Profile determines a group of settings in the H.264 Codec. It doesn’t impact performance and gives access to a set of features that are key to streaming, so this should always be set to High.
• Look-ahead: Unchecked for most content, checked for low motion games. This allows the encoder to dynamically select the number of B-Frames, between 0 and the number of B-Frames you specify. B-frames are great because they increase image quality, but they consume a lot of your available bitrate, so they reduce quality on high motion content. Look-ahead enables the best of both worlds, but struggles with high motion content as it needs to change too often. This feature is CUDA accelerated; toggle this off if your GPU utilization is high to ensure a smooth stream.
• Psycho Visual Tuning: Checked. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement.
• GPU: 0. If you have 2 GPUs in your system, you can select which one is used to encode. This is not recommended, as NvEnc is already very efficient and the little gain you can get from using a second card is lost by having to copy the frame to the second GPU.
• Max B-Frames: Set to 2. For low motion content (i.e. adventure games such as Tomb Raider) you can increase this to 4. B-Frames increase image quality but consume bitrate, which decreases image quality on movement. If you see pixelation or artifacting on your stream you may want to reduce this.
  • Note: If you stream to Mixer using FTL, it is recommended to turn B-Frames off. Mixer relies on WebRTC to playback FTL streams; most web clients cannot handle B-Frames, so Mixer recommends using 0 B-Frames with FTL.

Recording Settings

• Type: Standard.
• Recording Path: This is the directory where the videos will be saved. Make sure the hard drive you select has enough space!
• Recording Format: FLV; or MKV if you use multiple audio tracks.
• Audio Track: Leave it at 1 for default; you can add more audio tracks if you are using more sources.
• Encoder: NVIDIA NVENC H.264 (new).
• Rate Control: We recommend CQ, although VBR with high bitrates will also produce good results but with larger file sizes.
• CQ Level (CQ): 15 for CQ (or less if you want higher quality).
• Bitrate and Max Bitrate (VBR): 40,000 Bitrate; 60,000 Max bitrate. You can increase these to 100,000 and 200,000 (respectively) for higher quality.
• Keyframe Interval: 0 or 2.
• Preset: Select Max Quality. If you get encoder overload issues, change this back to Quality.
• Profile: Set to High.
• Look-ahead: Checked.
• Psycho Visual Tuning: Checked.
• GPU: 0. If you have 2 GPUs in your system, you can select which one is used to encode.
• Max B-Frames: Set to 2. For low motion content (i.e. adventure games like Assassin’s Creed) you can increase this to 4.

ABOUT NVENC
NvEnc is NVIDIA’s encoder. It’s a physical section of our GPUs that is dedicated to encoding only. This means that your GPU can operate normally regardless of whether you use this region to stream or record. Other encoders, such as x264, use your CPU to encode, which takes resources away from other programs such as your game. That’s why using NvEnc allows you to play games at a higher framerate and avoid stuttering, giving you and your viewers a better experience.

In the last two GPU generations we have made great improvements to NvEnc, helping deliver best-in-class output quality. NvEnc in the GTX 10-series GPUs provides superior quality than x264 Very Fast, the most commonly used x264 preset. And in the new RTX 20-series, NvEnc performs better than x264 Fast and on par with x264 Medium, a preset that requires an expensive dual PC setup.

One thing that is great about NvEnc on the RTX 20-series is that all GPUs have the same NvEnc with the same performance and quality, from the RTX 2060 to the RTX 2080 Ti. NvEnc also benefits from our own NVIDIA Video Codec SDK, an advanced set of tools that help improve the encoded quality and that we constantly update to help you get the best out of your NVIDIA card.

Finally, if you are using an NVIDIA GPU you have access to GeForce Experience’s Game Filters, which allow you to further improve the image quality of your viewers via software by enhancing color, adding sharpness, or introducing cool effects.

ABOUT THE GEFORCE-OPTIMIZED NEW VERSION OF OBS STUDIO
We have collaborated with OBS to improve support for NVIDIA GeForce GPUs. The new OBS Studio, version 23.0, will leverage the NVIDIA Video Codec SDK, which will greatly improve performance and reduce the FPS impact of streaming and recording. We have also tweaked some of the background settings of NvEnc to improve quality, especially for the RTX 20-Series GPUs.

HOW TO DEBUG PROBLEMS
Streaming can be very complicated, but it’s particularly hard to debug. There are many things at play when you stream, so we are going to try to provide you some help on how to identify what is going wrong and how to fix it.

Components

• Streaming uses the following components:
• Your PC: This includes hardware and software.
• Local Internet: WiFi or cabled internet + your Router.
• Your connection: To your service provider.
• The platform: Twitch, Mixer, Youtube, etc.
• Viewer’s Internet: Typically Wi-Fi, but can also be 3G/4G.
• Viewer’s device: keep in mind 35% of Twitch viewers are on mobile.

If something is failing, we want to first identify what component may be failing, so we don’t go crazy trying to fix something that was never broken in the first place. Typically, this means that the first test you should do is a Speed Test to make sure that you don’t have internet problems in your local internet or your connection. Second, make sure the platform hasn’t issued an alert that they are down or are experiencing problems. Then based on what error you get, you start looking at one thing or another in your PC.

How to check what’s happening to the encode
OBS Studio includes a very useful tool: the Stats Window. To bring it up, click on View > Stats. This window will show you Lagged and Skipped frames, Dropped frames, and Encode FPS.

This window will show you:

• FPS at which you are encoding.
• Latency to encode each frame.
• Missed Frames — problems with GPU.
• Skipped Frames — problems with CPU.
• Dropped Frames — problems with network.

Common Error Types

Stream is missing FPS. The stats window will show missed frames. While streaming and missing frames, pull up the Task Manager > Performance, Click on GPU and check the 3D load and Encoder load.
